U Scram Cat & Chipmunk Deterrent
For the most unique idea in a cat repellent, look no further than U Scram Cat & Chipmunk Deterrent. This system puts up an invisible fence around an area that you want protected, and allows you to target specific places, like gardens or sandboxes, using only scent as a deterrent. U Scram employs essential oils that cats hate, placed on little triangular cork trees that press into the ground around an area you want protected. One whiff and the cat will take off running. The oils will not wash off and they can be easily re-soaked with essential oils when their effectiveness wanes. Organic, non-toxic and biodegradable, it will keep cats from entering any area where the cork trees have been deployed.
