The average lifespan of a cat is about 12 to 17 years. Many domestic cats typically live around 13 to 17 years, though some can live much longer, reaching up to 20 years or more with proper care. Indoor cats usually live longer than outdoor cats because they face fewer risks and dangers. Various factors influence a cat's lifespan, including breed, genetics, whether the cat is spayed or neutered, diet, health care, and lifestyle. Some specific details include:

• Certain breeds like Siamese, Burmese, and Persians tend to live longer (15 to 20 years).
• Mixed breed cats often live longer than purebred cats, likely due to fewer inherited diseases.
• Spaying or neutering a cat can increase its lifespan by reducing reproductive cancers and risky behaviors like roaming.
• The oldest recorded cat lived to 38 years.

Indoor cats generally live 12 to 18 years and may reach their early 20s. Outdoor cats tend to have shorter lifespans, often 2 to 5 years, due to hazards such as traffic, fights, and toxins. Overall, with good care including regular vet visits, a balanced diet, and a safe environment, cats can live comfortably into their mid to late teens or even beyond.
