We have used a range of slow feeders, many more attractive than Super Feedy. But the dogs engage with it, and the space between raised sections makes it easier to put food in and to get a regular brush in for cleaning. None of our dogs have more than 3 cups of food in one go, so we wish they were smaller. However they stack easily which makes carrying a few bowls easier, and having the lick mat as a lid for packing food for trips is a great idea. We have one dog who is not interested in food and needs all night to eat a bowl. We gave him a super feedy to engage him in hunting for the food and be able to access it pretty easily, and aince then he has put on weight and his bowl is close to empty each morning.
