I think everyone has been civil so far. We all love our animals, and it is obvious that the original poster loves Toby, or she wouldn't be trying to help him! Whether or not it is because he was declawed, he is, quite simply, who he is. With patience, perhaps he will learn not to bite - how old is he? And as you suspect he may have been abused, (who could abuse dat pretty cat?) I think being extra calm around him, speaking in soothing tones, and heck, pet him wearing gloves if you need to, just to get him used to the fact that you mean him no harm, and a human's touch CAN feel good!
