A 4-year-old cat is not considered an old cat. Cats generally start to age when they are over 7 years old, so a 4-year-old cat has just entered middle age. The average life span of cats is more than ten years old. All the organs of a cat’s body around 4 years old are functioning very well, and they are relatively strong. ​​​​​​

Cats generally start their first estrus between the ages of six months and eight months, which means they have reached sexual maturity. A 1-year-old cat is equivalent to about 18 years old in humans, and a four-year-old cat is equivalent to 30 years old in humans. Around the age of 18, the body is relatively at its peak, and it is generally not easy to get sick. Even if you are sick, you will get better quickly. The functions of various organs in the four-year-old cat's body are also very good. Cats after four or five years old will slowly enter the old age stage. Most cats can live more than ten years old, and their average life span is about sixteen years old. Most four-year-old cats have shiny hair, are agile, and have a strong appetite. It is generally recommended that cats of this age undergo a physical examination once a year.

Although the overall physical condition of four-year-old cats is good, cats’ natural sensitivity has nothing to do with their age. Owners should pay attention to reducing stress when raising cats and perform regular physical examinations on cats, so as to detect physical problems of cats as early as possible and extend the life of cats.
