How Old is Your Cat in Human Years?

Cats mature very rapidly during their first two years of life. Unlike the old "multiply by 7" rule, veterinary science shows that the first year of a cat's life is roughly equal to 15 human years, and its second year brings it up to 24 human years.

Our Cat Age Calculator simplifies this conversion. After their second year, every additional cat year is generally equal to about four human years. Calculate your feline friend's age accurately using this tool!
