Good but not for clever food orientated cats!
Bought this to feed our cat at regular times as we work shifts. Unfortunately he can get his paw up through the entry door and pull food down so isn't very effective for giving specific amounts of food. As he's prone to weight gain I don't want him to get more than he should so will be returning this and looking at a different type of automatic feeder. However, if your pet isn't quite so persistent I can see this being great as you don't have to refill very often.
