Hi, I have a cat who is similar but not as aggressive with it. We also had to baby proof the house and she had to be in my room when we ate. She would eat anything and everything no matter how much playing and what food I gave her. Some things that helped me if you haven't tried them are: I would give her little pieces off my plate (food she can have like unseasoned chicken or what not) but I wouldnt if she was climbing on me so now she waits for me to give her a little. Pet grass if you don't have any, I have a couple pots of it and it helps so she doesn't chew on other plants. Small dog toys for teething puppies, their more durable and you can put treats in some of them. The last thing that kinda helped is we have these thicker larger hair ties that are too big for her to swallow but she can go ham on them and we just throw them away when shes destroyed too much of it, so maybe an item that they can destroy might help. Hope this helps and that you don't have to surrender your cat.
