Why it matters

This fountain separates clean and used water into independent tanks, so cats always drink fresh water and there are no filters to replace. That removes the main running cost of a fountain.

A 2,000 mAh USB-C battery runs it for up to six months per charge, per FEELNEEDY. The drinking surface is 304 stainless steel; the tanks are plastic. It holds 3.5 L and runs at about 30 dB.

Who it's for, and who should skip it

Good fit if

  • Owners avoiding filter costs
  • Spots without an outlet
  • Single or two cats

Look elsewhere if

  • Owners who won't recharge
  • Very heavy drinkers
  • Cats that drink without triggering a sensor

Pros and cons

Pros

  • No filters
  • Up to 180 days per charge
  • Fresh-water separation

Cons

  • Empty the used-water tank
  • Plastic tanks
  • Larger footprint

Limitations to weigh

  • Take the fountain apart and clean the pump at least weekly; slime builds fastest in warm rooms and with wet-food eaters.
  • Empty and rinse the used-water tank whenever you refill the clean tank.
