It is best to change the litter after a month after the cat has given birth to kittens, or not. Generally, after the kittens are gone, the mother cat will take the kittens out for a walk, and they will choose a comfortable place to sleep, so There is no need to specially change the kitten's litter. Moreover, it is best for family members not to touch kittens frequently, otherwise the mother cat will feel unsafe if she smells other strange smells, and then take the kittens to other places and hide them, so there is no need to take care of the kittens. Take good care of the mother cat. That's it.
