# Deciphering Cat Ages & Phases

Of all of the myths involving companion animals, one which continues to persist (and nonetheless drives me batty) is the notion that cats (and canines) 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 very 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 apply. 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 potential. Let’s now think about copy. Cats and canines 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 cause that cats age sooner after they’re youthful and decelerate after they’re older.

### Learn how to examine cat years to human years

A lot 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 under consideration. (See sidebar.) In line with 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. This can be a extra logical strategy and, in my expertise, it appears fairly correct. Be aware: This chart doesn’t apply to canines. Canine have completely different age equivalents relying on their measurement (massive canines have shorter life spans than small canines, 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 principally based mostly on semantics, and whether or not you are typically 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 in all probability pleased with this six-stage model, though as a cat veterinarian, I had combined 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 wise. Nonetheless, dividing youthful grownup cats into “junior” and “prime” felt a bit contrived.

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

Kitten:  start to 1 yr

Younger grownup: 1 to six years

Mature grownup: 7 to 10 years

Senior: Older than 10 years

In case you’re a lumper, you in all probability 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 ought to be additional divided, leading to a five-stage classification that, in my view, covers all of the bases:

Kitten: start 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 believe some folks really feel that the phrase geriatric is simply too scientific, or that it carries adverse 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 marvel and makes the cat sound like a superhero, which is a fairly cool idea.

### Discovering the suitable care in your cat at every stage

The principle cause veterinarians divide a cat’s life into levels is to assist us formulate well being and wellness plans which can be applicable for that specific life stage. The diseases and behavioral adjustments we’re prone to encounter, and the diagnostic assessments which can be really useful, will differ relying on these levels. Whether or not you, as a cat father or mother, 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 private desire. 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 reside longer than ever earlier than, and that’s one thing we will all agree is great information.
