I have to agree with sasvermont. I knew a couple who RV'd with their cats all the time and they always had them declawed. The provided all kinds of toys and stuff and the cat was very happy. It could be that this cat was treated agressively after he was declawed and that is why he bites. There is no way of knowing, sadly.

However, I do believe that declawing is a choice. When I first got Bassett I looked into it because she travels with me a lot in the car, and I didnt' know if I would be able to train her for having her claws trimmed. I phoned around to different vets and got all sorts of opinions. We all have a right to agree or disagree with it but it's not fair to put down the people who made that choice for a valid reason.
