Query: does not work

I bought this product to keep cats out of the vegetable garden. If you turn it to high sensitivity then it goes off when a car goes by, a tree limb blows in the breeze, etc. If you turn it down so it doesn't go off so easily, then it will not pick up an object as small as a cat. After try high, low, and all settings in between, I stopped using this product.
