Cat Age to Human Age Conversion Calculator

Determine if your cat is old or young in relation to human age. Use this app to convert cat age to human age.

This calculator uses a method developed by Monsieur LeBeau. After one year, your cat or kitten will have the equivalent age of a fifteen year old person. At two years, the pet will have an equivalent age of twenty four. Between two and fourteen calendar years, the cat will age at a rate of four human years. After fourteen calendar years, the feline will age at a rate of two human years.

The method above is more accurate than linear estimates. The commonly used linear estimate is seven cat years for each human year.

Note: This calculator give a rough estimate and may not be accurate for all breeds of cats. The life expectancy of animals is usually directly related to size. A large animal usually has a shorter life than a smaller animal. See a veterinarian for age related questions or any other health concerns for your pet.
