Rhino,

I would never suggest declawing, so no worries there. I would strongly
suggest putting a scratching post near the areas they scratch, so they
scratch the post and not your bed/mattress.

Our youngest cat was scratching the boxspring near the front of our
bed, and I used Sticky Paws on that (the double sided tape sold for
deterring cat scratching). I'm not sure where the areas are, but you
could try using Sticky Paws over the area.
