I got two of these for my cats. I'm fairly happy with this. Other options have had reviews where people expressed concern over their cats being able to pry open the top to access the food or the pet cutting themselves on sharp edges. There are absolutely no concerns like these on this one. The only reason I didn't give it five starts is 1) because it's intended for dogs, so it's huge and takes up a lot of floor space, and 2) it takes 4 D batteries, and needs new batteries every 2 months. I sometimes worry that the batteries will die when I've left my cats alone for 24 hours, and that did happen once, but it wasn't that big of a deal.
