Which cat breeds live the longest?
Burmese, Siamese, and Russian Blue cats are among the longest-living breeds, often reaching 15 to 20 years. Most domestic cats live 13 to 17 years with good indoor care.
How long do Maine Coons live?
Maine Coons average about 12 to 15 years. Routine heart (HCM) and hip screening, a lean weight, and indoor living help them reach the upper end.
How long do indoor cats live?
Indoor cats commonly live 12 to 18 years, and many reach their late teens or twenties. Indoor living is the strongest predictor of a long feline life.
