A four-year-old cat is equivalent to a 32-year-old human. A one-year-old cat is equivalent to a 15-year-old human, and a two-year-old cat is equivalent to a 24-year-old human. The rate of aging accelerates after the first two years. After that, a cat grows about four years' worth of age each year. Cats enter their senior years after seven years old, during which time regular checkups are necessary.

Domestic cats generally have a better living environment than wild cats, so they typically live longer and are in better physical condition. To ensure your cat grows up healthy, if there is no intention to breed it, it is recommended to have it spayed/neutered as soon as it reaches adulthood.
A cat's nutritional needs vary at different stages of life, so feeding should be adjusted according to its age. Feeding should be done at regular times and in measured amounts to establish a consistent eating habit. The primary diet should consist of cat food, supplemented with small amounts of cooked meat, vegetables, and fruits to achieve a balanced diet.
