The Two-Tank HydroSplit™ Fountain

Fresh Water for Her. A Waste Tank for Everything Else.

HydroPurr pumps only clean water, every used drop drains into a sealed waste tank. Open it after a week and see exactly what your cat isn't drinking anymore.

Your Cat's Fountain Is a Hot Tub With No Drain, and She Drinks From It All Day.

Take the shell off any fountain in the pet aisle and you'll find the same machine: a bowl of standing water and a little motor stirring it. Nothing ever leaves. The spit, the fur, the crumbs off her chin, it just sits in the gunk, growing bacteria.

You scrub it Sunday; the film is back by Wednesday. That's because you cleaned the part you can see, the colony lives in the seams and inside the pump housing you can't open. And carbon filters pull out chlorine, not bacteria: the filter is just the subscription on top.

HydroPurr is built like plumbing instead. Clean water waits in a sealed tank her tongue never touches; the steel tray drains every used drop into a separate waste tank, one way, gone. Open the waste tank after a week and you'll see exactly what she used to be drinking.
