This is a great option for people who like 2 feed the cats certain amount of portions per day and also have an option when you travel or go out for dinner. However I will say out of my two cats that one has figured out how to put his paw up the shoe and pull food down from what's been Prime for the next feeding. I think the manufacturer still has some room to improve the products design to prevent this kind of behavior for example they could limit and funnel the chute so that a paw could not go up there.
