Contech CatStop Automatic Outdoor Cat Deterrent

Protect your garden, plants or sandbox without chemicals or fences. When cats come within range, the Contech CatStop 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 CatStop in the garden or outdoor area that you want to protect, and it's ready to go. Monitors up to 280 square feet (26 square meters)
