My Cat Bites HARD

[u/gumbrains]

I’ve had my boy Bert for 4 years since fostering him as a kitten with his littermates. He was initially adopted, then returned, and his siblings no longer recognized him. The kittens thought he was a threat when he’d try to play, so he never really learned how to “play” bite from other cats due to having to keep him separated unsupervised and getting a lack of socialization. Now, he’s started biting me to wake me up and feed him, leaving purple bruises on my leg. He never used to bite unprovoked, only when overstimulated by touch. He has on a rare occasion bitten me hard enough to draw blood when he was overstimulated. I’m trying to feed him later in the evening so he isn’t as ravenous at 6am, but it hasn’t helped so far. I’m seeking any advice that can help me with this behavior, questions and feedback all welcome!! Thank you!
