Keep Kitty Out of Houseplants

Our new kitten, Bill, has taken to using my houseplants as his litter box. I’ve taken various bits of advice: cover them with aluminum foil (waste of foil…and none too effective), add in some hot sauce around the edge where he stands (nope, has just decided he’s a spicy kinda kitty).
But…eureka! The answer was lying in a nearby woods.
Pinecones are the perfect deterrent. Uncomfortable to walk on, eco-friendly and aesthetically pleasing.
Thanks again Mother Nature!
