I think my cats are smarter than yours, Potawie, they only eat the plants when I'm not around.I shoot my cats with a super soaker when they get into my plants, and they learn quick
in india they rub ghost peppers on fence posts to keep elephants away
I can honestly say that since I have been using the cayenne powder on my plants my elephant problem has been resolved! Not one elephant in sight! However, the cats are a different story. Just made a cocktail of coffee/cayenne/thyme and a small dash of dish soap and misted them with it. Hope I don't do more damage than the cat does!
