I know most folks here at Pet Talk oppose declawing, and I think it ought to be a last resort, but it's not the "awful" thing it's made out to be for most cats. My first two babies were front declawed and had NO PROBLEMS whatsoever. They climbed trees, dug in the cat box, jumped on everything and generally enjoyed life like any other cat would.
Declawing shouldn't be undertaken on a whim, but I think it's not the terribly horrible thing it's always made out to be, either. Some cats don't handle it very well, just like some of us humans don't handle certain surgeries very well.
enough fussing, I hope your kitties do well with the inflatable furniture. Providing a really good scratching post and trimming the claws are good ways to train kitties to stay away from the furniture.
