Why does my kitten bite my face and how can I prevent this behavior?

Kittens may bite your face as a form of play or to show affection, but it can also be a sign of teething or overstimulation. To prevent this behavior, redirect your kitten's attention to appropriate toys, provide plenty of playtime and mental stimulation, and avoid rough play that may encourage biting. Consistently reinforce positive behaviors with rewards and avoid punishing your kitten for biting. If the behavior persists or becomes aggressive, consult a veterinarian or animal behaviorist for further guidance.
