My cats are very finicky with new items (cats are finicky, shocking!). However, they really seem to like this water fountain. It was a slight pain to put together, as there are a lot of parts, but it is worth it. Surprisingly, it holds a lot of water, but doesn't take up too much space. For reference, I've included a photo of my 8-lb cat drinking from it. Unlike the other water fountain I owe, this one is VERY quiet--I can't hear it even when standing next to it. If you are in the market for a water fountain for your beloved pet, I would highly recommend this one.
