The typical lifespan of a housecat is around 12 to 15 years, although many can live well into their late teens or even early twenties with proper care. Factors such as genetics, lifestyle, diet, and healthcare can significantly impact their longevity. Indoor cats generally live longer than outdoor cats due to reduced risks from accidents, predators, and diseases. Regular veterinary check-ups, a balanced diet, and a safe, stimulating environment contribute to a cat's health and longevity. It’s essential for cat owners to be aware of their pet's needs and to provide them with a loving and safe home to maximize their lifespan.
