A 7-year-old cat is roughly equivalent to a 45-year-old human, and the average lifespan of a cat is 18-20 years. While a human is in their adolescence at 18, a cat is already considered old at 18.
After a cat reaches 8 or 9 years old, it officially enters its senior years, and its physical condition gradually declines. Pet owners need to take more careful care of their cats, paying attention to indoor hygiene and providing them with a quiet, comfortable, clean, and tidy living environment.
