The average lifespan of a cat depends on various factors such as care, nutrition, environment, breed, and genetics. The average cat lifespan is between 13-17 years, but some cats can live up to 20 years or more. The oldest cat on record, named Creme Puff, lived to be 38 years old. Indoor cats generally live longer than outdoor cats, with an average lifespan of 12-18 years, and some may live to be in their early 20s. Outdoor cats generally live shorter lives due to being more likely to be involved in traumas such as motor vehicle accidents or dog attacks, and they are more susceptible to several life-threatening viruses. The lifespan of mixed-breed cats is typically one to two years longer than purebred cats, as they are affected by hereditary illnesses less frequently. Breed-specific lifespans vary too, so purebred cat parents should take their kitty’s breed into consideration as well. For example, Maine Coon cats have an average lifespan of 10-13 years, while a Siamese can live to be 15-20. As cats age, they undergo physical and behavioral changes, and their immune system becomes less able to fend off foreign invaders. It is important to keep cats up to date on their vaccines and routine examinations, maintain a healthy weight range, provide a stress-free environment, and engage in moderate playtime to help them live happily through their golden years.
