About This Tool
### How Old is Your Cat, Really?
Cats are mysterious, but their aging doesn't have to be. While the old "1 cat year = 7 human years" rule is popular, it's not accurate.
Cats mature very quickly in their first two years, then the aging process slows down.
### The Real Formula
* **Year 1**: Equals 15 human years (Teenager).
* **Year 2**: Equals +9 human years (Total 24 - Young Adult).
* **Year 3+**: Equals +4 human years for every year.

Frequently Asked Questions
How long do indoor cats live?
Indoor cats often live 12-18 years, with some reaching their early 20s. Outdoor cats have much shorter life expectancies (avg 2-5 years) due to cars, predators, and disease.
When is a cat considered a 'Senior'?
Cats are generally considered seniors around 11 years old (equivalent to ~60 human years). Geriatric care usually begins at age 15.
Do breeds age differently?
Unlike dogs, most cat breeds age at a very similar rate. However, some breeds like Siamese or Burmese are known for living longer than average.
