Remy sometimes gets destructive. Parts of the cat tree are missing the fabric covering because he rips it off. He chews the corners of my couch for no apparent reason. He just tried chewing my mattress. I don't know why he does it. I don't really care if he ruins my couch because it's already junk, but I want to understand why he gets like this sometimes. He has tons of toys and I play fetch with him when he wants to. It's like he sometimes has so much energy that it manifests as destruction.
