I HATE my couches and want to get new ones but I have two cats that are not declawed. I will be sad if we spend the money on great new couches and then the cats destroy them. Is their any material that is better than another that can withstand the scratching or not make scratches so noticeable?

Cats have scent glands on their paws, so once they begin to scratch in certain places it leaves a scent marker they need to keep topped up every time it begins to fade. As your cats have been using your couch as a scratch post it has become impregnated with their claw scent. Before you get rid of the old couches, remove a section of fabric from the areas where the cats have been scratching and wrap this around a scratch post, or use it to cover a plank of wood. The scent will attract your cats to scratch these items instead of your new furniture.
