Understanding Cat Aging
Cats age much faster than humans, but not in a perfectly linear way. The common "1 cat year = 7 human years" myth is actually inaccurate.
The Formula Explained
- Year 1: Rapid maturity. A 1-year-old cat is basically a teenager, equivalent to a 15-year-old human.
- Year 2: They reach full adulthood, equivalent to a 24-year-old human (+9 years).
- Year 3+: Aging steadies out to about 4 human years for every cat year.
Life Stages
Kitten (0-6 mo)
High energy, rapid learning.
Adult (3-6 yrs)
Prime health and activity.
Mature (7-10 yrs)
Activity may decrease slightly.
Senior (11+ yrs)
Requires more frequent health checks.
