Deciphering Cat Ages & Levels

Of all of the myths involving companion animals, one which continues to persist (and nonetheless drives me batty) is the notion that cats (and canine) get older at a tempo of seven years for each human yr.

Frankly, this concept has by no means made a lot sense to me. We’ve all seen (or at the least know of) cats who’ve lived to the age of 20. The truth is, at one level I had over 30 20-year-old cats in my veterinary follow. Utilizing the 1-equals-7 rule, a 20-year-old cat can be the equal of a 140-year-old individual, which merely isn’t attainable. Let’s now think about copy. Cats and canine can get pregnant and produce offspring as early as 6 months of age. Utilizing the 1-equals-7 rule, a 6-month-old cat is equal to a 3½-year-old human. Can folks have infants at this age? After all not! The 1-equals-7 rule doesn’t work for the straightforward purpose that cats age sooner after they’re youthful and decelerate after they’re older.

The right way to examine cat years to human years

A variety of years in the past, the American Affiliation of Feline Practitioners (AAFP) and the American Animal Hospital Affiliation (AAHA) collaborated to create an age-comparison chart that takes this into consideration. (See sidebar.) Based on this chart, a 1-year-old cat is equal to a 15-year-old individual, and a 2-year-old cat is sort of a 24-year-old individual. After that, you add 4 human years for each cat yr. It is a extra logical strategy and, in my expertise, it appears fairly correct. Be aware: This chart doesn’t apply to canine. Canines have completely different age equivalents relying on their measurement (huge canine have shorter life spans than small canine, for instance). Cats are all roughly the identical measurement, so the chart is common for cats.

What number of life levels do cats have?

One other matter associated to age and longevity is cat life levels. There are a number of opinions on this topic however no consensus. The variations are largely based mostly on semantics, and whether or not you are usually a “lumper” or a “splitter.” Lumpers choose to group some levels collectively into a bigger class, whereas splitters choose to subdivide the levels. The one widespread floor amongst all of the variations is the primary life stage: kitten.

The up to date age-comparison chart talked about above additionally describes the life levels of a cat, dividing it into six distinct levels:

Kitten: 0 to six months

Junior: 7 months to 2 years

Prime: 3 to six years

Mature: 7 to 10 years

Senior: 11 to 14 years

Geriatric: 15 years and older

Splitters have been most likely pleased with this six-stage model, though as a cat veterinarian, I had blended emotions. I by no means knew precisely the place to attract the road between “grownup” and “senior.” Dividing older cats into “mature,” “senior” and “geriatric” classes based mostly on these age ranges appeared smart. Nonetheless, dividing youthful grownup cats into “junior” and “prime” felt a bit contrived.

In a lately up to date (2021) report, the AAFP/AAHA described 4 fundamental age-related feline life levels:

Kitten:  delivery to 1 yr

Younger grownup: 1 to six years

Mature grownup: 7 to 10 years

Senior: Older than 10 years

When you’re a lumper, you most likely love this streamlined model. I’m content material with the primary three classes and their related age ranges; nevertheless, I really feel that the senior stage must be additional divided, leading to a five-stage classification that, for my part, covers all of the bases:

Kitten: delivery to 1 yr

Younger grownup: 1 to six years

Mature grownup: 7 to 10 years

Senior: 11 to fifteen years

Geriatric: 16 years and older

I’ve seen variations of the variations described above, however with the time period “tremendous senior” changing the time period “geriatric.” I think some folks really feel that the phrase geriatric is just too scientific, or that it carries destructive connotations. As a veterinarian, I choose the time period geriatric, though I perceive why cat mother and father would fancy the time period tremendous senior, because it invokes awe and surprise and makes the cat sound like a superhero, which is a fairly cool idea.

The primary purpose veterinarians divide a cat’s life into levels is to assist us formulate well being and wellness plans which might be acceptable for that individual life stage. The sicknesses and behavioral adjustments we’re more likely to encounter, and the diagnostic assessments which might be beneficial, will differ relying on these levels. Whether or not you, as a cat dad or mum, choose the four-stage classification (kitten, younger grownup, mature grownup, senior), a five-stage model (kitten, younger grownup, mature grownup, senior, geriatric) or a six-stage mannequin (kitten, junior, prime, mature, senior, geriatric) is a matter of non-public choice. As a cat veterinarian who feels that every one cats die too younger, the truth that so many life stage charts acknowledge the existence of a geriatric or tremendous senior stage tells us that cats live longer than ever earlier than, and that’s one thing we are able to all agree is great information.
