It may be that the female cat has given birth to too many kittens and has no strength and doesn't want to eat them. The mother cat can supplement the appropriate amount of nutrition by eating the placenta of the kitten. It doesn't matter if she doesn't eat it. The breeder can help the mother cat deal with it. Female cats will lose a lot of nutrients after giving birth, and breeders must supplement them to prevent female cats from becoming emaciated after giving birth.
