Cats lick their wounds for several reasons:
I. Instinctual Grooming Behavior
- Natural self - care: Cats are meticulous groomers by nature. Licking is a fundamental part of their regular grooming routine, and this instinct extends to when they have a wound. In the wild, they would use licking to keep their fur clean and free of debris, and the same behavior is applied to the area around a wound.
- Saliva properties: Their saliva contains certain enzymes that have mild antibacterial properties. In a natural setting, this could potentially help keep the wound clean and prevent some infections, so licking is an instinctual way to "treat" the wound.
II. Response to Discomfort
- Itching: As the wound begins to heal, it may become itchy. Licking provides a form of relief from this itching sensation. Just like a human might scratch an itchy area, a cat will lick its wound to soothe the itchiness.
- Pain or irritation: The presence of a wound can be painful or irritating for a cat. Licking is a way for the cat to try to comfort itself, as the repetitive motion may have a self - soothing effect similar to how a person might rub a sore spot.
