What owners tell us
-
“She drinks out of it constantly, like a little kid drinking from a water fountain. Huge success!”
-
“Peace of mind that her water is always clean and plentiful. So quiet I have to check it's even on.”
-
“My cat used to ignore her bowl completely. Now she drinks way more — and it's far easier to clean than plastic.”
FAQ
Questions, answered
-
Most cats adopt within a few days. Cats are naturally drawn to moving water — it signals freshness in a way a static bowl cannot. If after 30 days she hasn't taken to it, we will refund you completely.
-
Plastic fountains develop a biofilm she can smell. Steel does not. Many cats who refused plastic fountains drink readily from Catinio because there is nothing for bacteria to live in and nothing to smell. That said, every cat is different — the 30-day Cat Acceptance Guarantee exists precisely for this reason.
-
For this specific use, yes. Plastic scratches with every clean, and those scratches are where bacterial biofilm grows. Biofilm is the thin layer your cat can smell before you can see it — and it is often why cats walk away from their bowl. Steel is non-porous, so there is nothing to scratch and nowhere for bacteria to take hold.
-
The opposite. A quick rinse every few days and a full clean once a week. The parts are few, non-porous, and dishwasher-friendly — no corners or crevices for biofilm to hide in. Most owners find it easier to clean than a standard bowl.
-
Every four to six weeks, depending on usage and water hardness. Three replacement filters are included with every order — roughly a 90-day supply. Replacements are available as a one-off or on a simple subscription you can cancel anytime.
-
Yes. The reservoir is designed with multi-cat households in mind. If you have more than three cats, we recommend checking the water level daily and replacing filters slightly more frequently.
-
It runs at under 25 dB — below most people's threshold of awareness. Quieter than a refrigerator, quieter than most heating systems. Many owners tell us they forget it is on.
