I love these answers. It means I'm in good company. All these are good answers, if not hilarious, but you might also try moth balls in the litter box. They stopped my cats from getting into my house plants. Now I have one that just tries to climb the "tree". I have 2 cats and 1 dog and don't let the cats out at all and the dog is supervised. I had a cat before that got out accidently - he'd never been outside before - and an owl got him. Now, I understand the circle of life, but they can stick with the field mice and leave my kitty alone. But . . . . I still miss my buddy. Anyway, back on subject, try the mothballs. It may just help and they kill bugs that may be in the plants.
