So I thought the cat tree might help with Puff finding a safe spot and stop the attacks on Kota. However he did it again today. I really think he's playing but it's not an acceptable play. So I thought about the nail caps so if he swats Kota it's at least not going to scratch her eye or something. Anyone tried them? How do they work? How long do they stay on? Can they get them off? I don't want them to pose a chocking hazard.
