I can personally vouch for those pet fountains. We bought one about a year ago for Velvet, best purchase ever!!

Worth very penny. We even bought a spare in case the one we have stops working.
Velvet is the same way. She never drank water out of her dish, no matter how often I changed it and made sure to keep it clean. We even tried several dishes, thinking that would help, never did. She would drink water out of tub or we would have to stand with the water running out of the faucet while she drank. What a pain. :roll:
I have noticed an increase in urine output since we got the fountain, so I am happy to say she is getting enough or at least a lot more to drink now. I actually have to clean it out more often. :lol: Well worth it though.
