My adult cat wouldn't go near it for 5 days although always watching. Finally, on day 6 he drank so much water that I thought he was going to float away! Now he won't touch his old bowl. I had questions about delivery and other things. The seller replied to my email quickly and was very courteous. I highly recommend this water fountain/bowl and manufacturer.
Verified Purchase
Rechargeable cat water bowl.
I bought this cat watering system because it is rechargeable and can get placed any where. My cat drinks water but she was always putting her paws and emptying the bowl out. I saw people suggested these type of symptoms so I thought I would try it. She was a bit taken by it when she first saw it and didn't know what to think of it. Now she is drinking from it. It is very quiet running as well.

This fountain is perfect! Quiet operation and no splash back. It was easy to clean and assemble. I like the choice of settings for how often the water can flow from continual to motion activated, although the later is my cat's least favorite. So glad I found this!
