Comparison of Cat Ages
by Ron Kurtus (revised 18 January 2022)
Cats age more rapidly than humans. One year for a cat is equivalent to over five years of human life.
In the various phases of its life, a cat has different nutritional and health care needs. Older cats suffer from the same ailments as elderly people, such as arthritis and loss of hearing and vision. A comparison of the actual age of your cat and the corresponding age of a human can give you a good idea of how to take care of your pet and also to understand its behavior.
The same is true for dogs and other animals.
Questions you may have include:
- What are the age phases in a cat?
- What are the age phases in a dog?
- What is the life span of other animals?
This lesson will answer those questions. Animal Health Disclaimer

Most cats have a shorter life span that humans. With cats, a relationship between their age and the equivalent human age has been estimated as about five years. As they age, cats require different care, as do humans when they age.
