Summary

Good Housekeeping's top-rated fountain overall after testing 15 models — the quietest of the bunch, stainless steel bowl goes in the dishwasher, and the 3.2L capacity handles multiple pets for days. Comes with four filters included.

Our take
For pet owners who've dealt with chin acne or slimy plastic bowls, going all-stainless is a game changer. The 60-day battery life means you can put this anywhere in the house without worrying about cords.
For most dog and cat owners who don't need smart features, the Rellaty is the sweet spot: genuinely quiet, easy to clean, and built from stainless steel at a price that won't hurt. It's the 'set it and forget it' pick.
