Mothers may bite their kittens for grooming, discipline, stress, or other reasons.
It is not unusual for a mother cat to bite her kittens, as this behavior serves various purposes depending on the situation. One possible reason is maternal grooming, where the mother may nip or bite her kittens as part of the grooming process to clean them and stimulate their circulation. Another may be discipline or correction, as the mother teaches her kittens proper behavior and sets boundaries. She may also show aggression toward her kittens if she is stressed, anxious, or in pain. It is important to monitor the situation and consult a veterinarian or behaviorist if the biting becomes excessive or harmful to the kittens.
