We have been adopted by a semi feral cat. He's been at our house every night for the last 3 months. We've trapped and neutered him, and he's now gradually getting to trust us and becoming part of the family.
The only issue is he interacts with us using his claws and teeth which can get painful. He is fascinated by us, and keen to interact, but obviously doesn't understand the idea of being stroked. He will play, but not gently like a domesticated cat would. If you put a hand out towards him he'll grab it with teeth and claws. The teeth are usually gentle, the claws not so much.
Is there a way to effectively teach a cat like this to be gentle, or do we need to accept occasional injuries as the price of having him around?
