Why does a cat bite the scruff of another cat's neck? - in detail

A cat biting the scruff of another cat's neck is a behavior deeply rooted in feline instincts and social dynamics. This action is most commonly observed in mother cats, who use it as a method to carry or control their kittens. The scruff of the neck is a loose area of skin that, when gently gripped, triggers a reflex in kittens causing them to become still and compliant. This allows the mother to move her offspring safely or discipline them when necessary. In adult cats, this behavior can also occur during mating, where the male may bite the female’s scruff to immobilize her, ensuring successful copulation. Additionally, biting the scruff can be a display of dominance or a way to establish hierarchy within a group of cats. In social interactions, a dominant cat may use this action to assert control over a subordinate, particularly in multi-cat households or feral colonies. While this behavior can appear aggressive, it is often a natural and non-harmful part of feline communication. However, it is important to monitor such interactions, as excessive or forceful biting can lead to stress or injury, especially if the cats involved are not familiar with each other or if the behavior is misinterpreted. Understanding this instinctual act helps in interpreting feline behavior and ensuring harmonious relationships between cats.
