Cats typically live for 13-15 years, though the exact lifespan depends on their care and environment. In a home-raised household, with adequate nutrition and good veterinary care, male cats are estimated to live 13-15 years on average, while unmated female cats live 15-17 years. However, spayed/neutered male and female cats tend to live 1-2 years longer than the average lifespan. 
Generally speaking, indoor cats live longer than outdoor cats, which may be related to the more complex environment and higher risks faced by outdoor cats. It is recommended to feed cats scientifically, have them undergo regular checkups, receive regular vaccinations and deworming, spay/neuter them, provide appropriate exercise and play, a balanced diet, and a comfortable living environment to improve their quality of life and lifespan.
Ways to extend a cat's lifespan:
1. A scientific diet can not only help cats maintain a slim figure, but also make them healthier. For example, feed cats less salty food and don't let them eat table food. A healthy and scientific diet can extend a cat's lifespan.
2. A cat's lifespan is also related to its mental health. A cat that is consistently happy and content every day will naturally be healthier and live a longer life.
3. A clean and hygienic environment is crucial for a cat's health. Clean the room frequently and prevent dust and trash from accumulating.
