I had purchased the Petmate Deluxe model of the 50-ounce Pet Fountain for my cats. That works exactly as described and my cats drink more than they did from bowls of water around the house. I like blue, and the basic model seemed as if it would perform the same as the deluxe model. My cats still drink from this model, but it doesn't fit together as well as the deluxe model and, as a result, it often leaks, leaving puddles around it. If I purchase another, I will only get the Deluxe model.
