Cat Climber

In captivity, an average life expectancy for male indoor cats at birth is 12 to 14 years, with females usually living a year or two longer. However, there have been records of cats reaching into their 20s and 30s, with the oldest known cat, Creme Puff, dying at a verified age of 38. Having a cat neutered or spayed confers some health benefits, since castrated males cannot develop testicular cancer, spayed females cannot develop uterine or ovarian cancer, and both have a reduced risk of mammary cancer. The lifespan of feral cats is hard to determine accurately, although one study reported a median age of 4.7 years, with a range between 0 to 10 years.
Diseases
Cats can suffer from a wide range of health problems, including infectious diseases, parasites, injuries and chronic disease. Vaccinations are available for many of these diseases, and domestic cats are regularly given treatments to eliminate parasites such as worms and fleas.
