One of our four cats seems to love to play with the toilet
paper. I've had this problem before but they usually grow out of it. I have been throwing away shredded toilet paper or re-rolling half of a roll more frequently lately so it was time to figure out a way to stop it.
I know that one solution is to not put the toilet paper on the dispenser. But that simply is not an option for me. I'm even compulsive about which way the roll is put on the spindle.
Just use a long rubber band
and wrap it around the ends of the holder. A few weeks of that and most cats should lose interest and move on to play with other things that they shouldn't. (Perhaps you'll need a tip on keeping your cat out of houseplant dirt
