To the Hawaiian fellow who was seeking to shock the cats who are spraying on his cars.
All you have to do is place some citrus peels in the area where they pee. Maybe rub or spray some OJ or lemon juice in the exact area where they pee. All animals hate citrus. And, they usually take a good sniff before they pee, so… this really works! For me, this stopped the raccoons from pooping at my outside faucet. Stopped deer from eating my freshly planted flowers. The beauty is… I only had to put the peels out once and they never came back! I got this tip from Birds N Blooms magazine, years ago. And you don’t have be the bad guy who electrocutes cats, or poisons raccoons or deer. Try it and let me know how it works!
