When breeding cats, you must achieve basic maturity before they can breed and reproduce. Under normal circumstances, female cats have sexual and physical maturity earlier than male cats. According to general experience, short-haired cats are 12 months old after birth and long-haired breeds are more suitable for breeding at 18 months old after birth. There are a few cats, and they should be bred later.

Many owners are not unwilling to sterilize the cat, but choosing to let the female cat give birth to a kitten. However, the female cat has a kitten. First, they have to wait for the female cat to estrus. However, the organs in the body of the cat are not fully mature in the first estrus, which may cause difficult labor. Therefore, it is recommended that the owners allow the cat to mate when the cat is in estrus for the second time, and then get pregnant and give birth to a cat.

Kitten's estrus does not mean that it is easy to breed. This first estrus is called the initial estrus period. At this time, the reproductive organs have not yet fully developed. After a period of time, the reproductive organs of male and female cats have basically matured. The male cat's testicles can produce sperm normally, and the female cat's ovaries can discharge mature eggs and have a estrus cycle. If they are allowed to mate, they can get pregnant and give birth, which means that they have reached the stage of sexual maturity.

However, cats have just reached sexual maturity but not physical maturity, that is, cats' bones, muscles and certain organs have not yet reached full maturity. If they are bred and pregnant, it will affect the growth and development of the cat, making the individual smaller, prematurely aging, shorter lifespan, poor development of offspring, thin body, low survival rate, or many diseases, and the breed will degenerate. Therefore, it is necessary to maturate cats to achieve basic maturity before they can breed and reproduce. Under normal circumstances, female cats have sexual and physical maturity earlier than male cats. According to general experience, short-haired cats are 12 months old after birth and long-haired breeds are more suitable for breeding at 18 months old after birth. There are a few cats, and they should be bred later.

The size and weight of male and female cats cannot be too different. If the male cat is too big and the female cat is too small (for example, the male cat weighs more than twice that of the female cat), the fetus may be too big and cause difficult labor. Before bride, female cats must be healthy and weigh at least six pounds. Female and female cats who have been weak and sick since childhood are not suitable for breeding. If a weak female cat is forced to breed, the fatigue of pregnancy and childbirth may cause life danger.
