My dog is pretty picky as far as where she drinks and out of what so I was a little apprehensive about buying this fountain but I am so very very happy that I did. She drinks out of it with no hesitation and I've noticed even drinks more than she did previously. The fountain is also pretty quiet and has a very very light subtle fountain sound if you listen very intently, but otherwise you don't hear it at all. This was a great purchase.

I bought this fountain for my Persian cats. They need lots of water and no matter what I do, I couldn’t convince them to drink water! I bought this water fountain with no great expectations ; but I was so wrong! My cats love this fountain and are constantly drinking water. It makes virtually No sound. I would highly recommend this fountain!

This water fountain from my dog who weighs 110 pounds is absolutely wonderful and has met my expectations at first. My dog was afraid to near it. I pulled off the fountain Spicket and just let it bubble up through the hole. I had to entice him to use it byplacing pieces of cheese in the water, and he could not resist stretching himself out as far as he could to get the cheese. Eventually, he got over his fear and started drinking it, and this is the only bowl that I use for his water I have recently the fountain Spicket back into the hole and it is so quiet you can’t even tell it’s running. I love this and so does my petdozer.

The fact that the water is filtered makes me feel better as a critter parent. My water has been slightly discolored for months...the whole county has. I won't drink it so why should my babies. Took a little bit to get used to but now no problems.

The fact that it works just like it says it would

The water is continuously moving so bacteria doesn’t have a chance to grow and the light up window makes it easy to see when I need to add more water
