Eversweet 3 Pro -UVC

The water level window is clear enough that I can check it from across the room, and the quiet pump means my cat actually drinks more now. Set-up took under two minutes and it's been running for a week without a single refill.

The UV-C light gives me peace of mind knowing the water stays cleaner between full cleanings, and the setup was incredibly straightforward right out of the box.

My cat used to ignore her old fountain, but she drinks from this one constantly. The UVC sterilization runs quietly enough that I forget it's even on, and the water stays noticeably fresher between refills.
