Cat water fountain

A small pump-driven bowl that keeps drinking water moving and filtered, which some cats find more appealing than a still bowl.

Also called: pet fountain, drinking fountain, circulating water bowl

A cat water fountain is a bowl or tower with a quiet pump that circulates water over a spout or ramp and through a filter. Cats are wild-descended animals that evolved from desert dwellers and may drink little, so owners try to make water more inviting. Some cats do seem to prefer running water, and fountains encourage others to drink simply because the water is fresh and aerated. Evidence that a fountain raises intake in every cat is limited, so watch what your own cat does.

Fountains must be kept clean. Wash the bowl, pump and any tubing every week or so, replace filters on schedule, and top up the water daily, since slime and mineral build-up can put cats off. Ceramic and stainless steel are easier to keep clean than plastic. Place the fountain away from the litter box and food, and tuck the cord out of reach so it cannot be chewed.

If a cat suddenly drinks much more or much less, or urinates more, ask your vet, as these can be signs of illness. Offer more than one water source around the home.
