Cats are famously bad at drinking enough water, and running-water fountains are the most evidence-backed fix short of switching to a fully wet-food diet. The Catit Flower Fountain's petal stream is designed to catch light and movement in a way a still bowl can't, which is meant to trigger a cat's instinct to drink from moving sources.
We measured daily water disappearance against a control bowl for three weeks with two cats. Total consumption rose noticeably in the first week and held steady after — not a dramatic transformation, but a real, measurable increase that matters for kidney and urinary health over the long run.
Neither cat had ever shown interest in the bowl's edge. Both were drinking from the petal stream within a day.
A worthwhile investment for any cat that's historically under-hydrated or prone to urinary issues. If your cat already drinks well from a bowl, the upgrade is nice-to-have rather than necessary.
