The cat fountain works great, I really like the automatic on and off feature so it is not constantly running I haven't had to recharge the battery yet which I think is fantastic. And my cat loves drinking from it that is definitely getting more water this way.

Must Have Filters to Keep Water Clean and Fresh

These Casfuy replacement filters and prefilter sponges work perfectly with my cat fountain and help keep the water clean and fresh. I appreciate that each filter and sponge is individually wrapped, making it easy to store and replace them as needed. The multilayer filtration system effectively removes debris, hair, and impurities while keeping the water tasting clean. I’ve noticed a real difference in how long the water stays clear and odor free. Installation is simple and the fit is spot on. Replacing the filters on a regular schedule keeps the fountain running smoothly with great water flow. I highly recommend these to anyone already using the fountain as they are a must have for keeping your pet’s water clean and healthy.

I like the fact that it has a rechargeable battery instead of plugging into a wall outlet. The battery seems to last quite awhile probably due to fact that water isn't continually running. The cats all like it. I am pleased and so are my fur babies.

i got these at the same time I bought the water fountain. These refills fit great and are filled with carbon and whatever else is in there to filter the water and keep it fresh longer. Easy to rinse off and reuse as well. They are cheap enough to change out frequently and rebuy. Many filters I have seen are expensive but these are reasonably priced which led me to want to buy the water fountain and refill kits. Water stays clean and clear for a few months before I change it out.

I actually got this for dogs to help reduce dog slobber in the bowl. It was easy to understand the instructions for set up and I’m glad the replacement filters are included. I replace my filter about every 3-4 weeks depending on use. My dogs enjoy their fresh water and the battery charge last for at least a week before needing to charged.

Came pretty quickly. It was well packed and arrived in good shape. I will have to charge the battery before use. It isn’t too big for my short dogs and cat. I’m looking forward to not having to change the water every day.

I called to find replacement filters for cat fountain. Found these but it shows for a different fountain but by same manufacturer. The CSR researched and said they would fit. They're 1" smaller than original but working. I have since found filters AND sponges but y'all are out of stock...please hurry and get them in stock as they are more affordable

It is quiet and easy to use.

Our cat is afraid of everything, but after a few days, he first played with the water and then learned how to drink from the water fountain. Now he loves it!

This fountain is superior to others we've tried. I LOVE that its cordless. No robot vac grabbing the cord anymore. Stainless steal is easier to clean. Window to show water level is helpful. Very happy with it!

She seems to like it

I was worried my cat would be startled by the water spout but she made a beeline for it and drank right away. I’m very pleased with the fountain so far!
