Cats from the same litter can breed, but it is not recommended for cats from the same litter to breed. Otherwise, hereditary diseases will occur, which will be detrimental to the health of the kittens born. If the owner has a male and a female cat in the same litter, he must do a good job of isolating them when they are in heat to prevent them from breeding. If the owner really does not have the energy to take care of them, he can put one of them away. A cat was taken to a pet hospital for sterilization surgery.

Characteristics before and after cat reproduction:

Sexual maturity of male and female cats is generally 7 to 8 months old, that is, at this time, the male cat’s gonads begin to mature, and the testicles Can produce sperm; female cats produce follicles on their ovaries, show signs of estrus, and have the ability to reproduce offspring. This only indicates that the cat has reached sexual maturity, but it has not reached physical maturity. The cat's bones, muscles, internal organs, etc. are still growing and developing. Generally, male cats need to be 12 months old and weigh more than 3 kilograms, and female cats need to be 10 to 12 months old and weigh 2 to 2.5 kilograms to basically reach physical maturity before they can be bred and reproduce. If the cat is bred immediately after the first estrus, on the one hand, it will affect the physical growth of the cat. On the other hand, the offspring will have slow growth and development, many weak and minor diseases, and the excellent characteristics of the breed may be degraded. Therefore, breeding cats must be physically mature before they can be bred, that is, they can only be bred when they are in heat for the second or third time.
