About Kitten Years

Kitten Years helps cat owners answer one simple question: how old is my cat in human years?

A simple guide for cat people

Kitten Years was built to make cat age easy to understand. The calculator gives a simple estimate, while the month and year pages explain what different ages can mean for daily routines, growth, behavior, and care.

The site was created by Don and Robin, two cat lovers who have shared their home with several beloved cats over the years, including Sneakers, Cody, Sierra, and Timmy. They also foster cats who are waiting for new homes.

The site is designed to be friendly, practical, and easy to use on a phone. It is not a veterinary clinic, and the content should not replace advice from a veterinarian who knows your cat.
