How I Keep My Cats From Destroying My Furniture

Cat love to use their claws. It is how they play. I have heard stories of cats destroying curtains, shower curtains, and furniture. I have four cats that live inside my home and they do not claw up my furniture because I give them things to claw. Since they love cardboard so much I decided to make them a special playhouse. I made them their own IKEA cubical. Don't paint it or cover it with paper. Just give them the raw cardboard. They love it!
