Stellar

I love this device, but I need for Maya to love it, just as much as I do. Ever since I adopted Maya 2 years ago, I’ve noticed how she doesn’t drink as much water as she should. Now we’re being faced with possible kidney issues as her ph levels are high. So I was trying to think of ways to get her excited about water and a friend suggested a water fountain. This product was easy to assemble and I love that it is wireless and has the auto sensor option. Maya still doesn’t use this without a treat being placed, but I’m hoping in time her feelings towards this device, will change.

Close to what I was expecting and my cats like it

I was expecting the whole thing to be stainless steel but the filter tray is plastic. However it's still better than my old water fountain that was half plastic

I was expecting the whole thing to be stainless steel but the filter tray is plastic. However it's still better than my old water fountain that was half plastic. Unfortunately even tho it's stainless steel, the manual says to not put any of it in the dishwasher even though I kinda remember the listing saying it could be washed in the dishwasher. I like that it has a seethrough part to tell where the water level is and my cats seem to like it. Though they were scared of the spout so I just put the rubber thing in there without the spout and they seem to like that much better. Overall it's an improvement compared to my last water fountain but not perfect.

I just received the Casfuy SY-WO8L smart water fountain. It is the second fountain I have had in a year. With that being said the first was a different brand . This time I considered the fountain more on how it worked and not on the way it looked. I really liked the way the battery worked on the Casfuy and the spout . My babies have always tried to drink from the faucet in my sink so I do believe they are going to absolutely love the Casfuy. So far everything has gone great today and in about 6mos. I plan to return and give another review. Thank You so much, Shontelle , Alex & the kitty’s

Toki took to this fountain immediately! The setup was quick and easy, and I love that it’s cordless, no messy wires and easy to place anywhere. The stainless steel feels sturdy and clean, and it’s very quiet when running. The 3 water modes are a great feature, and the large capacity means I don’t have to refill it constantly. Most importantly, Toki is definitely drinking more water than before, which makes me feel great as a cat parent. Overall, a solid, well-designed fountain and totally worth it!

Seems to be well made and operates as advertised. One cat loves it, the other is working through her expected uncertainness about this new contraption but will be fine with it in a few days. It is silent and motion activated which will help battery last longer. It charged fully within about 1 hour after unpacking it. I'm sure that depends on the output of your charger (not included but plugs into any standard USB charger used for phones or laptops).

My cat is obsessed with fresh water so we looked at a LOT of fountains for her before we finally got this one. Setup was easy and the automatic mode is great. Once we got it set up, which was super easy, she was interested immediately and drank almost right away. I've never seen her drink for 6 minutes straight before. We've had it for a while now, works great and is easy to clean. Filters are easy to change too.

EASY TO ASSEMBLE AND OPERATE, AND OUR CAT LIKES IT

Our cat, who will be 21 in April, has some kidney issues, and we thought he would drink more water from a flowing fountain than from a static water dish, so we bought this fountain. It was easy to assemble, and it runs silently (except for the sound of the water). Over the course of a couple of days, our cat went from frightened to wary to curious to all in. We’re very pleased with the purchase.

Product came as advertised, and I love the motion detected water activation. The stainless steel design and look is nice and easy to clean. Only comes with one filter, so you need to buy more and they are a little pricey compared to other filters. But overall, it was a good purchase. My cats are still getting used to it because it is a new item to their eating and drinking area. They are proceeding with caution, I am sure in the next few weeks they will be just fine.

I love everything about this water fountain! It's so cool how it illuminates the blue indicator light whenever it is activated by me or my fur babies. They took to it right away. I think my cat loves it a little bit more than my dog. She seems fascinated by it turning on like it does (set on auto) and she will sit across the room and stalk it as if she's in awe. I'm hoping that this will help her get the adequate water she needs for a 16 year old cat with early kidney disease. Hopefully, this will encourage them both to drink what they need, and find joy in doing it with this neat gadget. Get your babies one. I'm sure they'll love it.

I love this water bowl. It helps Keep the water clean, especially because I have a Shih Tzu and her face gets dirty. When she drinks out of water. This always makes sure that the rest of the pets don’t have to drink her dirty water. I haven’t cleaned it yet but so far so good easy to put together. I don’t imagine it being difficult to up keep.
