Fresh, filtered, moving water, with a pump quiet enough for the bedroom.
Made by iPettie.
Why it matters
Many cats drink more when their water is moving. WhisperFlow keeps it filtered four ways and flowing, with a pump quiet enough (under 30 dB) that it stays plugged in at night.

When the water bowl just sits there
Still water collects fur, dust and bits of food, and a lot of cats walk right past a stale bowl. Plenty of fountains fix that but hum all night, so they end up unplugged. And refilling a bowl you can't see into means guessing whether it's empty.
Moving water, filtered four ways, under 30 dB
WhisperFlow keeps water circulating through a 4-stage filtration system, so your pet always has a fresh, flowing stream to drink from. The USB pump is rated under 30 dB, quiet enough to run beside the bed overnight. A built-in LED light shows the water level at a glance, even in a dark room.
