Protect your garden, plants or sandbox without chemicals or fences. When cats come within range, the Cat Stop automatic outdoor cat deterrent emits a sudden burst of ultrasonic sound (at a frequency most humans can't hear) - the sound startles cats, and teaches them to stay away. Installation is easy - just place the Cat Stop in the garden or outdoor area that you want to protect, and it's ready to go.
