I think this was our messiest puzzle yet - food was flinging everywhere! But he sure loved it. Unlike my dogs he tended to use his tongue to get the food instead of his paws. Maybe because his big feet don't fit between the blades?
He loved it though we'll definitely be using this one again in the future. I love that it is dishwasher safe too. Because of that and the shape of the bottom, you can even feed wet food in this one. Just be sure to place it on an easy to clean surface if you do though.
