I just ordered 2 of these from QVC. They are spill-proof "neater feeders"! They have a filter on top and any water filters to the bottom tray that is hidden - so if you have a messy dog like I do, the water will drip into the bottom instead of all over the floor. Can't wait until they come in! I bought both in size Small, and one in brown (for Sammy) and one in Cranberry (for Alexis). Will let you know how they work after they have tried them!
Oh, and if you're interested in checking them out yourself and checking out the on-air video, here is a link. They have them in 3 sizes - Large and Small for dogs, and a cat size which has wider bowls to allow for the cat's whiskers.
