"In general, cats live longer than most dogs. An average life span might be 12 to 14 years, with some cats reaching 20 and more. A cat's longevity depends on whether or not it lives indoors or is allowed outdoors (outdoor cats live an average of eight years), genetics, feeding, enviroment, veterinary care and some other factors. The general consensus is that at about age seven a cat can be considered "middle-aged", and at age 10 and beyond - old."

"In countries with good veterinary care, the average life-span of a neutered domestic cat (barring accidents) is considered to be 14 years old although there are signs that this may be increasing. More and more cats are reaching their late teens or early twenties. Life-span is determined by several factors: good genetics, good general care, good health care, good diet and a relatively safe environment. In the wild, cats fall victim to accidents, illnesses, food shortages and predators and may live 6-8 years."

"Indoor cats have an average life span of 12 - 20 years when compared to 1 - 5 years for a cat kept outdoors. "
