I'm gutted, even though it's a great product
Unfortunately, like only 1 other reviewer, this product seems to be ineffective for my situation. Bought 2 and the greedy cat took to it immediately, but the one who likes to graze won't go near it. He doesn't want to put his head under the arch, and the motor sound terrifies him. Alas, I was so excited for this and feel really sad. Otherwise it's a great product.
