Front declawed cats can still climb trees but they do not have a major defense which is to defend themselves with their front claws. I think it best to have your cat as inside only with supervision if you want to let him out.
As far as biting, my cat will give you a warning swat with his front paws first with a warning vocal (no mistake when he does this). If you don't back down he will bite, but it is a warning bite and does not break the skin just enough to let you know "leave me alone". If you still come after him he will bite harder and it's kinda like a cobra, a real strike.
The husband use to play with him too rough and he would do this and than say, "The cat bit me!" Well, I would tell him he sure gave you enough warning. This is one
reason that the husband is now an X!
My cat dosen't bite at all now just nibbles for attention, usually my ankles when he is hungry, it doesn't hurt.
I only had potty problems when my cat was still sore from surgery but not after.
I guess all cats are individual but it also on how you treat your cat. Before the husband came in the house (I had my cat before I got married) he did not bite at all! All cats will defend themselves if needed and a declawed cat will defend himself the best way he can.
Note: My cat was declawed 13 years ago - before I knew better to not do this. Now, knowing better I would not have declawed him.
