I have a 15 month old male flying squirrel. Lately he's begun to attack my hands and feet. He lunges at them and bites them, not in a playful way. He's broken skin barely once and has left several marks. Then he does this weird leg dance where he kinda rubs himself on me but kicks his legs around. Could this be a sign of sexual tension due to not being neutered and a lack of a mate, or is this just a sign of aggression and domination? Please help I would love to have my sweet boy back!
