Contech StayAway Automatic Pet Deterrent

The StayAway Automatic Pet Deterrent protects your porch, patio, potted plants and countertops. Just place it in the area you want to protect, and the StayAway does the rest. When a cat approaches the area, the StayAway responds with a warning sound and a brief spray of compressed air to warn your pet. Once your cat learns to recognize the warning sound, you can switch to the sound only mode to conserve compressed air for an even more economical solution.
