What is the name of the bump on a cat? - in detail
The small, raised area on a cat’s body, often referred to as a "bump," can be identified as the "scruff" or "scruff of the neck." This area is located at the back of the neck, where the skin is looser and thicker compared to other parts of the body. The scruff is a natural feature in cats and serves multiple purposes. In kittens, the mother cat uses this area to carry her young, as the loose skin allows her to grip them gently without causing harm. The scruff is also a sensitive zone that triggers a reflex known as the "scruffing response," which causes kittens to become still and relaxed when held by this area. In adult cats, the scruff is less commonly used for handling, as their weight and size make it less effective. However, it remains a notable anatomical feature. Additionally, the scruff is sometimes used by veterinarians or caregivers to administer certain treatments, such as injections, as the skin in this area is less sensitive to pain. While the scruff is not typically referred to as a "bump" in scientific terms, its prominence and functionality make it a distinctive and important part of a cat’s anatomy.
