The feeder is serving and is no less than assumed by the two cats, but the lining slips often after barely and only sparsely, which is the less, of course, the less dry food is in the "tank". There's a star deduction, since this lack probably could be solved quite easily when the bowl would have a sloping floor. Fortunately, our cats are so resourceful and clever, and the forage fish by yourself after. But a larger Hundepfote not fit well through the feed opening.
Despite a buy recommendation from me, because as the daily filling of dried fodder will be invisible and you (just not as well as in a well), yet accessible can store it relatively odorless.
