The average lifespan of a cat is 12-15 years. However, depending on the cat's breed, living habits and living environment, the individual lifespan of a cat will vary greatly. Normally, the average lifespan of domestic cats is about 2-5 years longer than the average lifespan of stray cats, but for some specific breeds of cats, even domesticated cats may have a shortened lifespan due to congenital inherited diseases, such as Cats carrying the fold-ear gene, Mankikang, etc.

In addition, an unhealthy and irregular diet can shorten a cat's lifespan. Most people feed cats with cat food for a long time, even bad cat food. These cats may die around age 10. Bad cat food contains too much starch, which produces energy but not protein, shortening the cat's lifespan.
