I live in an apartment that has blinds on the windows. The blinds belong to the complex. The problem is my 6 month old kitten Gizmo has taken a fancy to playing with the blinds on the back door. It's a single door that opens onto a patio (I live on the second floor). He doesn't bother any of the blinds on the windows, but there's one on the back door he likes to jump on. I've even caught him going through them once. He's already bent some of the individual vanes. The blinds on the door are attached at the bottom and not made to be raised. I shoo him off of them when I'm there, but I know he's doing it while I'm gone too. Anything I can do to keep the little imp away from them?
