It’s pretty horrible and should not be done. Get the cat some things to sharpen on, and give up the desire for billows of silk draperies. I don’t know if all these animal cruelty things need laws, but declawing cats is cruel. As is docking dogs’ ears, chopping tails, etc.
Who are you to say what I can and can’t do with my property? Cats are not persons. Get over it.
