Feline Lifestages Information


All Lifestages


AAFP/AAHA feline life stage guidelines (2010)

Vogt AH, Rodan I, Brown M, Brown S, Buffington CAT, LaRue Forman MJ, Neilson J & Sparkes A Journal of Feline Medicine and Surgery 12 pp43-54 gives tips on which tests to run at which age, dental care, weight management and many other issues.


Senior Cat Care


The American Association of Feline Practitioners (2009)

Pittari J, Rodan I, Beekman G, Gunn-Moore D, Polzin D, Taboada J, Tuzio H & Zoran D Journal of Feline Medicine & Surgery 11 pp763-778 has guidelines on how to be proactive in caring for a senior cat. It recommends six monthly veterinary check ups.

The American Veterinary Medical Association

has some information about aging cats. I am a bit mystified that a seven year old cat is considered geriatric, yet is the equivalent of a 54 year old human. Aging in cats: common physical and functional changes (2016) Bellows J, Center S, Daristotle L, Estrada AH, Fickinger EA, Horwitz DF, Lascelles BDX, Lepine A, Perea S, Scherk M & Shoveller AK Journal of Feline Medicine and Surgery 18 pp533550 suggests:

  • 7-10           mature or middle-aged

  • 11-14         senior

  • 15+            geriatric

which makes more sense to me.


Major Feline Health Issues

Feline Lower Urinary Tract Disease (FLUTD)


This condition is very common in cats. It is usually linked to an imbalance in urine pH, and many of these cats develop struvite crystals. It is not the same thing as a urinary tract infection.


In the worst case, these cats can develop a life-threatening urinary tract blockage, so the cat becomes unable to urinate. This can be fatal, so If you suspect your cat has this problem, you need a vet, NOW! My Harpsie nearly died of this problem so it is a subject close to my heart.
