Speaking of the declawing issue. I have a cat and she never clawed furniture, well we got new couches and in anticipation of her wanting to mark the new stuff, I got her a new sratching post, but I also got these two sided sticky things that you put on your couch in the places they like to sratch (usually the corners) The residue doesn't harm the furniture and the cat's don't like to touch sticky stuff. They worked great, just a little FYI
If you get a bengal you will have to post some pictures they are really neat.
