CatStop Automatic Outdoor Cat Repellent keeps cats out of your garden, safely and efficiently, with a motion-activated burst of ultrasonic sound. Protect your garden, plants or sandbox without chemicals or fences. When cats come within range, the CatStop™ automatic outdoor cat deterrent emits a sudden burst of ultrasonic sound (that humans can’t hear) — the sound startles cats, and teaches them to stay away. Installation is easy — just place the CatStop in the garden or outdoor area that you want to protect, and it’s ready to go.
