This toy has potential, but hasn't scored with my cats. It was a little tricky to figure out how to open it. The instructions were stored inside. This is no reflection on the product, but my food-loving cat is also lazy. She likes the food on the floor, but doesn't seem inclined to bat this ball around for more to come out. I haven't given up, but did put it away until another day. We all know cats are flaky with their toys!
