I bought this bowl (530ml size) because one of my cats often ate all the dry food and then promptly threw it up again. We use it with dry food for my 3 small korat cats. They do scoop out the kibbles and then eat them but this is still slows them down and we hardly have any 'binge eating' vomits any more. If you do have a cat that binge eats and is then sick, definitely try various designs as we also bought the Savic gobble stop bowl but it didn't work for us.
Our (smaller) medium sized cat had trouble getting his mouth to the wet food; he tended to hook out the wet food and sometimes dispersed a piece over the floor unnoticed by him, so cleaning up required by us. I didn't try dry food as I've got the Stimulo and the Northmate Catch to help slow down his eating of dry food. With brushed outer and polished inner, that cleans more easily, this is a good product though for those it will work with.
