Query: Your cat will GAIN weight.... not lose weight

DO NOT waste your money on this expensive piece of crap. My cat learned how to steal food from it within 10 minutes. I tried taping the cover down (as recommended by the manufacturer) and that doesn't work. She quickly figured out that she can still steal the food from it. It just takes her a few minutes longer. I bought this feeder to help my cat lose weight and it has done the opposite.
