This pet fountain is such a neat item to have.  Our kitty doesn't drink a lot and I was constantly dumping and washing her bowl.  The Creekside Ceramic Pet Fountain eliminates the need for daily water changes.  It features filters built inside that keep Missy's water fresh.  The constant movement of the water is important too.  Our kitty was very apprehensive at first to try it.  I placed it where her other water bowl used to be,  set her dinner down next to it (usual place) and let her lick my finger from the bowl.  She was willing to try it then.  The water is a very gentle flow so I think most pets will come to like it very soon.  I love it for the convenience and the whisper quiet operation.  I think your small dogs and cats will love this and so will you!
