Calculate a cat's age in human years and cat years.
Learn how to use the Cat Age Calculator and its working principles
This calculator converts a cat's age into human equivalent years using a simplified formula where each cat year is approximately equal to 7 human years. This is a general estimation and does not account for the different life stages of cats, as cats mature faster when they are young and slower when they get older.
If your cat is 3 years old, the calculator will show that your cat is approximately 21 human years old.
