I really am at the end of my rope. I have been brought to the point of tears and I don't what to do. i have 10 cats. 8 have their claws, 2 do not (declawed before I actually knew what went into it, haven't done it since in 7 years). One of my cats will not stop scratching. He only scratches the carpet outside my bedroom door, and my bedroom door. There are scratches all over the door, and a 5 inch wide area where he's totally pulled off all the carpet. I have tried nail caps, double sided tape, foil, putting a scratcher on the doorknob, opening the door and squirting him with water, scat mat, the motion activated air spray stuff. NOTHING WORKS. He is not phased by any of it. And it's making me hate him. Really and truly. He's destroyed the carpet that I saved for 3 years to get. It's in turn destroyed the relationship I have with my cat. I really don't know what else to do. Help me.
