Understanding Cat Aging
Cats do not age linearly in human terms. Their rapid development during their first two years means they reach maturity much faster than humans.
The Veterinary Formula
- Year 1: 15 human years
- Year 2: +9 human years (Total 24)
- Every year after: +4 human years
| Cat Age | Human Years | Life Stage |
|---|---|---|
| 1 | 15 | Kitten |
| 2 | 24 | Young Adult |
| 5 | 36 | Adult |
| 10 | 56 | Mature |
| 15 | 76 | Senior |
