  • This is usually one of the first questions people ask themselves after diagnosis. 

  • This page attempts to help you understand a bit more about what the test results mean, and why they do not tell the whole story.

  • It also explains why it is not as bad as it sounds when your vet says your cat has lost a certain percentage of his/her kidney function.

How Bad Are My Cat's Results?


There are a number of ways in which the vet can determine how advanced your cat's case is. Most vets will start with bloodwork, and many will also analyse your cat's urine (urinalysis).


Many vets now take the test results and categorise them according to the system proposed by the International Renal Interest Society. This divides CKD into four stages based on blood and urine test results; so if your vet tells you, for example, that your cat is in Stage 2, s/he is probably referring to the IRIS staging system. There is more information on this below.


Remember, your cat's test results are only part of the story. There are other factors at play, including how your cat is acting, how proactive your vet is, whether there is an infection etc. For this reason, we have a mantra on Tanya's CKD Support Group: treat the cat, not the numbers.


Bloodwork tells vets quite a lot about how a cat's kidneys are functioning. BUN (urea) and creatinine are the two main measures of kidney function in bloodwork. Here is the IRIS staging system, with my estimate of the likely percentage of function lost:


Stage of Disease

Blood Values:

US Measurements (mg/dl)

Blood Values:

International Measurements (µmol/L)

Approx. Level of Kidney Function Lost

Stage 1

Creatinine below 1.6

Creatinine below 140

 0 - 65%

Stage 2

Creatinine between

1.6 and 2.8

Creatinine between

140 and 249


66 - 75%

Stage 3

Creatinine between

2.9 and 5.0

Creatinine between

250 and 439


76 - 90%

Stage 4

Creatinine over 5.0

Creatinine over 440

Over 90%

*It is normal not to be able to detect CKD until at least 66% of function has been lost, because before that there are usually no symptoms, see below. Therefore for cats in Stage 1, bloodwork values are usually within the normal range, and kidney problems would only be suspected if an anatomical or functional abnormality had been detected.


In all cases, two readings in a stable cat (who is not dehydrated - this can make the numbers look a lot higher than they really are), ideally after fasting (though that is not always the best choice for a CKD cat), are required before making a firm diagnosis of CKD. In practice, most vets will make the diagnosis based on bloodwork taken once during your initial visit.


Urine Specific Gravity (USG)

Because of their desert heritage, healthy cats have concentrated urine. The normal range is 1.008 to 1.060 but a cat with a more dilute USG, below 1.040, is generally considered to have a problem of some kind. A CKD cat will probably have a USG between 1.008 and 1.012. 


Other possible causes of dilute urine include liver disease, diabetes, hyperthyroidism or use of corticosteroids. Cats with pyelonephritis (kidney infection) may have low USG.


Once a cat is receiving regular fluid therapy, this test can be rather unreliable; but it may be helpful when blood tests first indicate a possible problem, particularly if your cat appears to be in early stage.


There is more information about USG on the Urinalysis page.


The International Renal Interest Society has information on the significance of USG in cats.



The International Renal Interest Society (pages 3 and 4 for cats) also mentions the importance of proteinuria when deciding how advanced a cat's CKD is.


Healthy cats only have tiny amounts of protein in their urine because their kidneys do not allow the protein to leak through. In CKD cats, this mechanism can be faulty and excess levels of protein in the urine, known as proteinuria but sometimes referred to as microalbuminuria, may occur.


The usual way to determine if a cat has proteinuria is via the urine protein:creatinine ratio (UPC):


Urine Protein: Creatinine Ratio

Proteinuria Status

Below 0.2

Non Proteinuric (NP)

Between 0.2 and 0.4

Borderline Proteinuric (BP)

Over 0.4

Proteinuric (P)


There is a correlation between the severity of the proteinuria and the prognosis. However, don't panic if your cat's level is over 0.4 because the UPC ratio is not always accurate - for example, blood in the urine, infection or inflammation may give a false positive result. Hypertension may worsen proteinuria, so getting blood pressure under control may lead to an improvement in the UPC ratio. Even if your cat's UPC ratio is indeed high, it may gradually reduce with treatment.


Relation of survival time and urinary protein excretion on cats with renal failure and/or hypertension (2004) Syme HM, found that cats with a urine protein:creatinine ratio below 0.5 survived almost three times as long as cats with a urine protein:creatinine ratio of over 0.5.

Survival of cats with naturally occurring chronic renal failure is related to severity of proteinuria (2006) Syme HM, Markwell PJ, Pfeiffer D & Elliott J Journal of Veterinary Internal Medicine 20 pp528–535 confirmed the results of the earlier study above.

Idexx Laboratories is now offering a new test in a number of different countries which can calculate the protein:creatinine ratio.

How to integrate UPC ratios into your practice and uncover early renal disease is a video presentation about the new Idexx test (this lasts an hour).


Percentage of Function Lost                                                                             Back to Page Index


You may well panic if your vet tells you that your cat has lost two thirds or more of his/her kidney function. I regularly hear from people who say things like "my vet told me my cat has lost 75% of kidney function and it's looking really bad".


Take a deep breath. It is probably not as awful as you fear because it is actually normal for CKD not to be diagnosed until a cat has lost at least 66% of kidney function. The What Happens in CKD? page has more information on why this is the case.


What you need to focus on is the fact that cats with CKD can often manage quite well on limited kidney function - for some cats, things only become critical when they have lost as much as 90% of function, and there are  some cats who cope astonishingly well with even less function. So the goal is, not to worry about the function that has already been lost, but to try to help your cat manage with whatever function remains for as long as possible.


Chronic Kidney Disease versus Chronic Kidney Failure                            Back to Page Index


You may also be frightened because your vet says your cat's kidneys have failed. Fortunately, this may not be as bad as it sounds.


There are a number of different expressions used to describe chronic kidney disease. It used to be widely known as chronic renal failure (CRF), and for many years this website was known as Tanya's Comprehensive Guide to Feline Chronic Renal Failure.


I decided to changed the name in 2011 and use the expression Chronic Kidney Disease (CKD) instead. This was for two reasons. Firstly, it is the term most commonly used in the academic literature. Secondly, I think it more accurately reflects the nature of the disease, and focuses on the important word, "chronic" rather than on that awful word, "failure", which tends to scare people, making them feel the end is nigh.


Chronic means that CKD is an ongoing disease. This is good news, because it means that in many cases it can be managed. For this reason, some vets prefer to use the word "insufficiency" for early stage cases instead.


Whatever expression your vet uses, try to focus on the chronic aspect of CKD.


End Stage Renal Disease (ESRD)                                                                     Back to Page Index


This expression literally means that the cat's kidneys are at the point of failure and there is no longer anything that can be done. Some vets use it in this sense, referring to a cat who is rapidly becoming unable to deal with the CKD, ceasing to respond to treatments and likely to die very soon. However, other vets use it to mean any cat with numbers in the range of Stage 2 or 3 (see above), when in fact many cats in these stages can live for a long time.


Try to clarify what your vet means by ESRD, and if he/she merely means that your cat has high numbers, consider treating the cat; the numbers may come down with treatment, and even if they don't, your cat might be able to handle high numbers as Thomas did. Even if your vet thinks death is imminent, it may be worth treating your cat regardless to see how he or she responds; cats are real fighters and can often pull through.


Obviously though, you don't want your cat to be in pain when it is a hopeless situation. It is not always easy to tell when a CKD cat has come to the end of the road - The Final Hours contains details of the symptoms you are likely to see towards the end, and discusses making the painful decision to let go.


If Your Vet Has Recommended Euthanasia


When vets tell people there is no hope for their cat, it is usually based on test results as outlined above, particularly blood tests which show high kidney values. However, I have heard of vets who tell people their cat should be put to sleep without doing any tests at all, based purely on the cat acting sick. I don't think this is appropriate. Your vet may be right, there may be no hope for your cat, but if you're thinking of making the irrevocable decision to put your cat to sleep, you need proper, accurate information on which to base your decision.


Even if you do have some blood test results, the numbers only tell part of the story. In Renal disease (2006), Dr D Polzin states "Severity of renal dysfunction as determined by serum creatinine concentration or measurement of GFR provides a less accurate means of assessing short-term prognosis than does the clinical condition of the patient. The relationship between magnitude of renal dysfunction and clinical signs of uremia is often unpredictable. Therefore, short-term prognosis should not be established on the basis of a single measurement of the severity of renal function. In addition, a single determination of renal function is unreliable as an index of the potential for improvement in renal function." In The laboratory diagnosis of feline kidney disease (2008) Heine R Veterinary Focus 18(2) pp16-22, Dr Heine states "cats can sometimes, especially in cases of acute kidney injury secondary to obstructive FLUTD, develop creatinine values of 1600-1800 μmol/L (20.98-23.6 mg/dL) and yet recover."


I don't know why some vets don't try to fight CKD. Perhaps they think it's not worth trying because CKD is incurable. Yes, CKD is incurable, but it can often be managed so your cat feels better. As one member of Tanya's CKD Support Group said, "vets are about the cure, we are about the care."


So try not to worry too much about which stage your cat is in, especially since numbers can be artificially inflated at diagnosis. The stages are supposed to help the vet roughly work out which treatments are likely to be needed, not to encourage them to write off cats in the higher categories. Yes, your cat's chances may be worse if your cat is - and remains - a high numbers cat; but some cats do well despite high numbers, so try treating the cat, not the numbers and see what happens.


Therefore, if your vet has told you there is no hope for your cat, and has recommended euthanasia, I urge you to:

  1. read this page, and also the Is There Any Hope? page to explore the various scenarios you may be facing;

  2. check out the Index of Symptoms and Treatments page to see which symptoms your cat has; and

  3. ask your vet about trying some of the Treatments that are appropriate for any of the symptoms you are seeing and any imbalances indicated by your cat's test results;

before making the irrevocable decision to put your cat to sleep. 

What Does All This Mean in Practical Terms?                                               Back to Page Index


You probably now know into which stage your cat falls, but that doesn't really tell you much about what you are facing on a practical level.


If your cat appears to be in Stage 4, don't despair. You may not be seeing the true situation. Bloodwork can look high for the following reasons:

  • the cat is severely dehydrated

  • the cat has an untreated urinary tract infection or a kidney infection

  • the cat has untreated hypertension (high blood pressure)

  • the cat has kidney stones

The most important thing for cats in all stages is to get food into them! See the Diet and Nutrition chapter for tips and hints.


In addition, you should monitor for:

so you can nip these problems in the bud if they are present.


In virtually all cases it is worth trying treatments for at least two weeks. The International Renal Interest Society has some suggestions on what to watch for and be prepared to treat at each stage, including what to do if proteinuria or hypertension are present.


Whatever stage your cat is at, most people find the treatments only take about 20 minutes out of their day, including the time needed to give sub-cutaneous fluids.

Here are some tips on what you may be facing:

Cat in IRIS Stage 1, Stage 2 or the Lower End of Stage 3

  • If your cat seems to fall into IRIS Stage 1, 2 or the lower end of Stage 3, it is early stage and with proper care and a little luck on your side, your cat could live for years.

  • Most cats in these Stages (creatinine below 3.5-4.0 mg/dl US or 300-350 µmol/L international) will not need subcutaneous fluids and can easily be managed with just a few treatments tailored to the individual cat's needs, e.g. treatment for stomach acid to prevent vomiting, constipation remedies and/or control of elevated phosphorus levels.

  • In all cases, it is essential that your cat eats!

Cat in Stage 4 or the Upper End of Stage 3

  • If your cat seems to fall into Stage 4 or the top end of Stage 3, don't despair. You may not be seeing the true situation. Bloodwork can appear high for the following reasons:


    • the cat is severely dehydrated
    • the cat has an untreated urinary tract infection or a kidney infection
    • the cat has untreated hypertension (high blood pressure)
    • the cat has kidney stones

    In such cases, the numbers you are seeing won't be an accurate representation of true kidney function. You need to treat your cat, particularly any dehydration, before you can know the true status of the kidneys.

  • Even if your cat proves to be at the top of Stage 3 or in Stage 4 following stabilisation, don't give up hope: some cats do seem to manage very well on very little kidney function, and it is possible that your cat might be one such cat. You will probably need to be more proactive and your cat will usually need more treatments than cats with lower bloodwork values, but it is certainly worth trying to help.

  • These cats will usually need the same treatments as cats in lower stages for whatever problems may be present, e.g. for stomach acid, high phosphorus levels, constipation etc. In addition, they will usually need regular fluid therapy in the form of sub-cutaneous fluids in order to avoid dehydration.

  • Cats in IRIS Stage 4 will often have anaemia, and will need treatment for that - untreated severe anaemia can be very dangerous and can kill a CKD cat before the CKD does. Fortunately, many effective treatments for anaemia are available, meaning no CKD cat need die of anaemia. See the Anaemia page for more information.

  • Cats in IRIS Stage 4 may have metabolic acidosis, so ensure your vet checks for that and treats it if it is present.

Please see the Is There Any Hope? page for more information.

Links on this page last checked: 03 December 2011


The group is hosted on yahoo!groups, part of yahoo. It has its own address separate from Tanya's website. You can either click here or copy and paste this link into your browser:




If you are already familiar with yahoo!groups, just click on the link and apply to join (and don't forget to complete the short questionnaire you'll be sent), but if you'd like to know more about how the group works, read on.


I own and run the group, but I am ably assisted by two moderators, Anne V and Anne A. They help with membership queries, approve messages, and do lots of boring admin stuff behind the scenes to help the group run smoothly for the members.


The group has various sections, including a photos section and a realtime chat function but for most people the most important part of the group is its message section. Basically, a member who wants support, vet recommendations, or to hear how others are coping with a particular problem, sends a message to the rest of the group. Other members then respond if they can. All messages sent to the group are stored in a message archive which members can search if they wish.


The group is private, i.e. messages sent to it are only visible to members, so people are not posting to the internet at large. The names of group members are also private, so nobody will know you are a member unless you choose to send messages to the group.


Joining the Group                                                                                                                        Back to Page Index


There are two ways to join the group, via the group's website or via e-mail:


How to Join the Group via E-mail

Just send an e-mail to


You should then receive an e-mail in response asking you to confirm that you definitely want to join the group. Just click Reply and send.


If you join the group via e-mail, you will be able to send and receive e-mails to the group, but you will not be able to access the group website and read the message archives or look at the photos. If you wish to do that, you will need to set up a yahoo! ID by visiting the group website.


How to Join the Group via the Web

You can visit the group's homepage and follow the instructions. If you do this, yahoo!groups will help you set up your yahoo! ID, which gives you access to the group message archive etc. A yahoo! ID is not the same thing as an e-mail address.


Here are the steps to follow. Don't worry, this all sounds far worse than it is! You should find that in practice it all works more smoothly than it sounds when you're trying to explain it in writing:


Existing yahoo! ID

  1. Go to the group website: http://pets.groups.yahoo.com/group/tanyas-ckd-support/

  2. Click on the Join this Group button and you'll be taken to a Sign In to Yahoo! page.

  3. Sign in and link Tanya's Support Group to your existing account.

  4. Choose the e-mail address you wish to use for the group (see below).

  5. There is a little box for you to tell me why you would like to join the group. You don't need to be inventive or fancy, it's not a competition, it's just an extra check by yahoo!groups to keep spammers out.

  6. Choose your message delivery options (see below).

  7. Scroll down and click on the blue Join button at the bottom right of the page.

New yahoo! ID

  1. Go to the group website: http://pets.groups.yahoo.com/group/tanyas-ckd-support/

  2. Click on the Join this Group button and you'll be taken to a Sign In to Yahoo! page.

  3. Scroll down a little and click on the Create New Account button.

  4. On the next page you can create your new account. Some people are somewhat inventive in their responses, but in such cases it is important to remember what responses have been given in case the information is needed later to access the account. I can't see any of this stuff, it's entirely private between you and yahoo!groups, so I cannot help in case of later queries. 

  5. Once the account is successfully set up, you'll be taken to a Congratulations! page.

  6. Before you click on the Continue button on the Congratulations! page, untick the box that makes yahoo! your homepage (unless that is what you want).

  7. Also click on the Edit Marketing Preferences link below the Continue button. This takes you to another page where they helpfully opt you in to everything, so go through and set it as you wish.

  8. Then on the same separate page click on Account Info at the top of the page. You will be asked for your password again and taken to the Account Info page. Click on Profile and opt out of the various choices as you wish. The key thing is, you do have choices here, you can make things as public or private as you wish.

  9. Now click on the Continue button on the original page. You will be taken back to the group page to choose your membership settings.

  10. Choose the e-mail address you wish to use for the group (see below).

  11. There is a little box for you to tell me why you would like to join the group. You don't need to be inventive or fancy, it's not a competition, it's just an extra check by yahoo!groups to keep spammers out.

  12. Choose your message delivery options (see below).

  13. Scroll down and click on the blue Join button at the bottom right of the page.

Membership Settings                                                                                          Back to Page Index


There are various choices you need to make regarding your membership of the group. The most important are which e-mail address to use, and which way you read messages sent to the group by group members.


Membership Settings: Your E-mail Address

You need to decide which e-mail address you wish to use for the group. If you have created a yahoo! ID, yahoo!groups will normally have also set up a free yahoo! e-mail account for you based on your new yahoo ID. You can use this e-mail address to access the group if you wish, but it's not essential, you can use any e-mail address you wish. Since yahoo! is now scanning messages for advertising purposes (similar to gmail), I would recommend not using yahoo! e-mail if possible (though it would probably be better than using your work address for private stuff).


If you do not want to use your free yahoo! e-mail address, click on Add e-mail address to add a different one. Be aware, if you don't add a new address here, yahoo! will use the yahoo! e-mail address as a default address. So if you don't receive the membership questionnaire, it may well be because it's gone to your new yahoo! e-mail address.


If you ever wish to change the e-mail address you are using for the group, you can do that here:



Membership Settings: Message Delivery

This sets up how you will access messages that are sent to the group.


This is a pretty active group. If you're looking after your CKD cat, you want support but you probably don't want a full inbox all the time. To help you manage this issue, you have three options for messages, and you can switch between them all as you wish:

  1. Individual E-mails

  2. Daily Digest

  3. Web Only (No e-mail)

Individual E-mails

This is the default setting. If you apply to join the group via e-mail, you will end up with this setting. If you apply to join the group via the group's webpage, if you don't choose one of the other settings, this is the one you will end up with.


This setting means that as soon as somebody sends a message to the group, it is sent directly to your inbox. It's a good choice if you might want to know immediately if somebody has responded to you, or if you would like to store some of the group messages for your reference. It's also good for being able to quickly delete messages which don't interest you.


The downside is that this is a busy group, averaging 50-100 group messages each day, so your inbox can quickly get full. One solution is to create a folder to use for group messages. All messages sent to the group have a tag in the subject line [tanya-crf] so you can filter all messages from the group to a new folder using this tag if you wish.


With both individual e-mail and message digest options, you can also choose the format of messages sent to you (Display Format), either Fully Featured (html, pretty colours etc.) or Traditional (plain text).


Message Digest

This means that you receive e-mails from the group, but yahoo!groups waits until there are about 25 messages available and sends them to you all in one go. With this option, you would therefore only receive 2-4 e-mails a day from the group, but it means you have to wait for responses (though you can still check on the group website for messages) and it can be more difficult to find what you are looking for within each digest.


With both individual e-mail and message digest options, you can also choose the format of messages sent to you (Display Format), either Fully Featured (html, pretty colours etc.) or Traditional (plain text).


Web Only (No Mail)

This means that you receive no messages at all from the group. This is a wise choice if you are using a work e-mail address, or if you cannot cope with the group's message volume. With this system you simply go to the group's website and read the messages that interest you there. Even if this is not your usual choice, it can be helpful to use this option if you are going on holiday.


So make your choices, then click the Join button at the bottom right of the page.


Important: Membership Questionnaire                                                           Back to Page Index

OK, so you've successfully applied to join the group. However, there is one more thing you need to do in order to join. I want to protect the group members from spammers, so whichever way you apply to join the group, you will receive a short questionnaire asking:

  1. Your first name

  2. The country where you live

  3. Your CKD cat's name and age

You need to respond to this before your membership will be approved.


Please don't worry about saying "the right thing." This is not a test to see if you are "good enough" for the group, everybody is welcome here, whoever they are or wherever they come from, as long as they want to help their cat. This questionnaire is basically just to reassure us that you are a real person applying to join rather than somebody trying to sell stuff and spam the group, but it also enables us to tailor our responses to your group messages e.g. if we moderators know where you live, we will not suggest treatments not available there.


Please note, only the two Annes and I can see your responses to these questions. The group will not know anything about you unless you choose to introduce yourself.


Once you respond to the questionnaire, your membership application should be approved very quickly (most people are approved within two hours or less).


Occasionally the questionnaire goes missing. You think we haven't sent it, and we think you haven't responded! If we haven't heard from you five days after you apply to join, we will send you a reminder. Unfortunately, we can only use the address you've used to sign up for the group, so if you've accidentally used your new yahoo e-mail address without realising it (see above), you won't see either the questionnaire or our reminder. If you don't hear from us, please simply write to us at tanyas-ckd-support-owner@yahoogroups.com and let us know. Please respond to the three questions in your response and we will either approve you (if your membership is pending) or send you a personal invitation to join the group (if your membership application has disappeared into a black hole).


Messages                                                                                                                                          Back to Page Index


Message Options: Sending Messages

You don't have to post, you can just lurk if you prefer.


If you wish to change the name that appears on messages you send to the group, Yahoo! explains how you can do that.


Starting a Thread

  1. You can simply send an e-mail to ask your question by sending it to tanyas-ckd-support@yahoogroups.com.

  2. You can go to the group website, click on Post Message in the sidebar on the left, and then write your message there.

Replying to an Existing Message

Messages sent in response to another message on the group also go directly to the group, not to the individual to whom you are replying. Therefore if you wish to respond to a message somebody else has sent, you can simply click reply on your e-mail programme. If you reply via the group website, you can click on the message in the group archives, then click reply which is top left above the message.


If you're changing the subject, or replying to a Digest (which have the subject line of Digest No. xxx), please change the subject line appropriately to something more meaningful. And please remove everything except that to which you are replying.


If you wish to reply privately to somebody, you will need to press reply, then delete the group e-mail address and paste their personal e-mail address into the To: line if you are using e-mail. If you are replying via the group website, you will see a little envelope over on the right under the person's name. If you click on that, your message will go to that person.


Message Content

You are welcome to discuss anything relating to care of your CKD cat. We do have a few guidelines we ask people to follow though:

  1. Please do not refer to vets or vet clinics by name for legal reasons. Just say "my vet" or "Dr J".

  2. Please do not ask for money or other donations.

  3. Since this is a very busy group, we ask that condolences are sent privately to the bereaved group member. Certain other messages should also be sent privately e.g. short "me too" messages, off topic posts etc.

  4. Please trim your posts.

Moderation of Messages

When you first join the group, your messages will be moderated for a short while. This means that they will not reach the group immediately, but will first be read and approved by one of the moderators. We do this to ensure that:

  1. you are not a spammer;

  2. you are keeping to other group guidelines (e.g. not naming your vet publicly);

  3. you are trimming your messages appropriately.

If you comply with the group guidelines sent to you when you join the group, you will be taken off moderation quickly. The main reason people stay on moderation is because they do not trim their posts. So please read up on this in the group guidelines. If you get stuck, just ask for help.


Leaving the Group                                                                                                Back to Page Index


Some people decide to leave the group. Their cat may have died, or they may find the message volume is too much, or they simply decide it's not the place for them. Leaving is fine, but if you're thinking of leaving simply because you cannot cope with message volume, please consider changing your message options first, such as by going no mail. This means your inbox will not be full, but you can still reach out for support quickly when you need it.


If you are leaving because your cat has died, please consider joining our sister group, Tanya's Feline Loss Support:

I do hope you've decided to join Tanya's CKD Support Group! It can give you support, it can give you hope. It can make you smile too - where else would people share your thrill at hearing that your constipated cat has pooped? (Believe me, when you've been dealing with CKD for a while, things like this are real triumphs which can absolutely make your day).


I personally read every message sent to the group. I don't respond to every post (my priority is running this website) but I do keep an eye on things and post occasionally if I can add to what has already been said.
