What can I do or buy to stop my cat from digging in my house plants?

We have 4 cats and only 1 is digging in my houseplants, is there anything we can do or buy something to make him stop? I thought there was a product that I could spray in my plants that wouldnt hurt them, tho stop my cats from digging, but cant think of it, can you?

Reply:Sticky paws is a good answer. :)



Also, consider getting that cat his own plant.



(I'm serious.)



You can buy cat "grass" seeds or catnip seeds. The cat will know this is his to chew on, and the others will probably join him in nibbling on the greens. Cats need some green/wild outdoors flavoring from time to time, and the grass or catnip makes them very content (and ...well... the catnip makes them strange for about a half an hour...) :)
Reply:You can try putting toothpicks in the dirt so it isn't fun to dig in. also, you could buy decorative rocks to cover the dirt. Again, not fun to dig in.
