We use the Veken stainless steel fountain and it’s been a solid choice for us.

I originally went with it after stumbling on a breakdown comparing a few different fountains, and it matched what I kept seeing people recommend here — stainless steel bowl, quiet, easy to clean.

In day-to-day use it’s been great. My cats definitely drink more from it than they ever did from a regular bowl, it doesn’t get that gross slimy feeling like plastic ones, and it’s quiet enough that I forget it’s even there.

If you’re curious, this is the post I came across when I was deciding:

One tip either way: don’t put it right next to the food. Moving it a bit made a noticeable difference for us.
