In addition, this behavior may also be a way for the mother cat to massage the kitten. In cats, this kind of massage behavior is a kind of social behavior, which can help strengthen the connection between family members and strengthen the relationship between them.
In a word, the behavior of the mother cat kicking the kitten is reasonable and natural, and there is no need for excessive worry or intervention. As long as the mother cat is healthy and behaves normally, kittens can usually cope with this behavior well. Of course, if you have any questions or concerns, please consult a veterinary professional.
