Cats come of age when they are six months old. Most adult cats are particularly energetic in the early morning and dusk. At this time, cats can run, jump and hunt. Puberty in cats comes quickly.
Generally, the first estrus of a female cat is from 7-8 months after birth to 1 year, which varies according to the cat species and living environment. Siamese cats are usually born at 7-8 months, and Persian cats are born at 10- 18 months. Recently, some Siamese cats began to estrus when they were five months old, which may be due to adequate nutrition raised by humans.
Male cats are in estrus at about 1 year old, 2-3 months later than female cats, and can mate to about1year old. Cats gather together to sing during mating period, which is often called "Cats call for spring" at night.
Cats develop much faster than humans, and stray cats that are not raised by humans develop the fastest. Usually, domestic cats are equivalent to 20 years old when they are one year old, 24 years old when they are two years old, and then every year they live is equivalent to four years' life. In other words, most cats can mate as long as they are one year old, and at the age of twelve, they are equivalent to 48 years old.
The average life span of cats is 18-20 years old. People are in adolescence at 18 years old, while cats are in advanced age at 18 years old. Puberty in cats is between 1-2 years old. 10-year-old cats can basically be considered to have entered the elderly society. After that, the owner needs to take care of the cat more carefully to make it live longer. See the table below for specific age stages:
1 month and a half = 4 years and 3 months = 6 years and 6 months = 10 years and 9 months = 13 years 1 year = 15 years.
2 years = 24 years 3 years = 28 years 4 years = 32 years 5 years = 36 years 6 years = 40 years old.
7 years = 44 years and 8 years = 48 years and 9 years = 52 years 10 years = 56 years 1 1 year = 60 years old.
12 = 64 13 = 68 14 = 72 15 = 76 16 = 80.
17 = 84 years old 18 = 88 years old 19 = 92 years old, 20 years old = 96 years old 2 1 year old = 100 years old.
