A motion sensor activates a warning sound and a brief, harmless spray of compressed air to keep your pet away. Cats hate it! But it can also be used on other small animals such as small dogs and birds. It's odorless, stainless, ozone-friendly, completely harmless.
Once your pet learns to recognize the warning sound, you can switch to "sound only" mode to conserve compressed air. The motion sensor and spray are separately adjustable so they can be positioned precisely.
Refill cans are available.
