How It Works
Cats mature rapidly in their first two years—a 1-year-old cat is roughly 15 in human years, and a 2-year-old is about 24. After that, each cat year equals approximately 4 human years.
Frequently Asked Questions
How long do cats live?
Indoor cats typically live 12-18 years, with many reaching their 20s. Outdoor cats average 5-10 years due to risks from traffic, predators, and disease. The oldest recorded cat lived to 38 years.
When is a cat considered senior?
Cats are generally considered senior at 11 years old (about 60 in human years). They may benefit from senior-specific food, more frequent vet visits, and accommodations like lower litter box sides.
Do indoor cats age differently than outdoor cats?
Indoor cats tend to live longer and healthier lives due to reduced exposure to diseases, predators, and accidents. However, they age at the same biological rate—they just have more years to enjoy.
