About the Munchkin
The Munchkin typically weighs 5–9 lbs as an adult and lives 12–15 years. Cats age uniformly across breeds, so this calculator applies the standard 15 + 9 + 4/year convention — what differs by breed is life expectancy and adult size.
Frequently asked questions
How do you calculate a Munchkin's age in human years?
Cats age at a consistent rate regardless of breed: ~15 human years in year one, 24 by age two, then about 4 human years per cat year after that. Enter your Munchkin's age above for the exact figure.

The typical Munchkin lives 12–15 years. Keeping cats indoors, maintaining a healthy weight, and twice-yearly senior vet visits push toward the top of that range.
