I was looking on this site for something to lock our bi-fold doors with (to keep Spooky out since he knows how to open them). I found something that is supposed to keep pets from unrolling the paper! One of the reviews said it helped with the scratching/shredding problem too, but I have never tried it so I don't know. We don't have this problem around here anymore, but I thought I'd share if you do!

I have to be careful of bringing in new toilet paper in. If we set it down (to go bring other stuff inside) he will eye it up and try to get into it to shred them.

). Then we can't close the door because we'd be locking them IN! CATS! Can't live with 'em, can't live without em
