Petkit filter 3.0
With the Petkit waterer my cat drinks a greater amount of water than she did from a plain bowl. And water consumption is SO important for a cat's urogenitury tract.

Super easy to use and clean. I really wish I had found this sooner. Im literally blown away by how great this is and at this price. I recommend getting the cleaning kit as its made for this and makes everything a lot easier. Again, I highly recommend.

Water fountain broke :(
I've had this product for about 6-7 months and loved it up until it broke today when I discovered that water got into the bottom battery block. Not even sure how that happened as I make sure to keep water away from the bottom of the base. Either way, it was nice for the first couple of months as it kept my cat well hydrated, but upset it didn't even make the full year mark like most of the reviews rave about.

Fresh water!
The filter worked to capture dust particles and hairs floating in the air. It's easy to rinse and even easier to replace when the time comes. My cat loves it.

Simple and effective
This does the job, filters dust/dirt/hard elements. My cat enjoys the fountain and ends up drinking more often. He likes the movement and the freshness

Fast Turnaround, Great Service
Precisely what I needed, and right on time! The old filter was kaput... but now my kitties can drink comfortably again. Love the fountain, and love all your products!

Love all of Petkit's Products
Love this water filter for my kitty! We bought stainless steel basic one and this one far surpasses our expectations! Love that it has a unique feature to turn off and run for a few minutes. Easy to clean and provides a really clean moving water!

Best purchase!
I am so glad we bought this fountain for our 14 year old cat. He has high normal kidney function and needs to drink a lot of water. He LOVES this fountain and is drinking more than ever. I love it because it is low maintenance and very easy to clean and replace the filter. And its filtered so I know its as clean as possible. Worth every penny!

Only one I trust
I looked for filters that could be cheaper but functional and the reviews said they were leeching particles into the fountain so I stayed with the real deal. It's worth it for the health of my cats. They love their uvc fountain and I have peace of mind.

Rare Review
A simply miraculous device. The design, first rate. Looks cool (to my human eyes and my cat seems to agree). The wireless power is genius. And all of this for a price that's hard to beat.
