This may not be just a joke. I had a cat who would not leave houseplants alone. She batted them, dug their dirt, chewed them, and knocked them over. I tried spraying her with water in a spray bottle, and for a while that worked. But eventually it seemed as if she was getting used to it and even enjoying it. Maybe it was refreshing on a hot day?
My previous post seems to have lost its image. I'll try to restore it but I don't know if this will work.
ETA: I wasn't able to restore it. Maybe a moderator will delete that thread?
