1 out of 3 cats
Only 1 of my 3 cats use this, but he loves it so much I have given 4 stars. He only likes to use 2 of the tumblers, he has big paws and finds 3 a bit awkward but it is good to have the option of adding/removing them. One of my other cats, with smaller paws fishes the food out of the spiky bottom piece which we fill as well. The tumblers tend to whizz the dry food all over the floor but he soon clears that up. A good buy.
