Some cats will be born prematurely under the influence of the outside world or the body. The bodies of 55-day-old kittens will be smaller and their constitution will not be as good as that of full-term cats. Breeders should take special care. There are also cats that will give birth after the fetus in the belly has stopped showing signs of life. In this case, the breeder should pay attention to cleaning up the big cat after giving birth to avoid causing inflammation and harming the big cat's body.
