Biting is the act of using the teeth to grip or cut into something. It can occur in various contexts, such as eating food, where it helps break down items for easier digestion. Biting can also be a natural behavior in animals, including pets like dogs and cats, as they use their teeth for grooming, playing, and defending themselves. In humans, biting can sometimes be a response to stress or frustration, especially in young children who may bite as a way to express emotions. Additionally, biting can lead to injuries or infections if not done carefully, making it important to understand the appropriate contexts for this action.
