Cat Amazing built the Brook Glass 90oz Pet Water Fountain to solve a simple problem: plastic and stainless steel fountains are hard to keep clean. This is the first all-glass cat fountain on the market. The key components—the basin, pump housing, and water pathway—are made entirely from glass. That matters because glass is non-porous and resists bacterial growth better than any other material. You can see the water level and clarity instantly, without lifting a lid or peering into a dark tank.

At 90 ounces, the Brook holds enough water for a multi-cat household or a small dog for several days. Cleaning is straightforward: the glass parts are dishwasher safe, and there are no crevices or seams where grime can hide. The pump is quiet, and the gentle waterfall flow encourages pets to drink more without splashing water everywhere. The design is minimal and looks more like a piece of tableware than a pet appliance.

One honest limitation: the glass construction makes it heavier than plastic fountains, so it won’t slide around, but you’ll want to handle it carefully when washing. It also costs more than a basic plastic fountain. For owners who prioritize hygiene and durability, that trade-off makes sense. The Brook comes with a one-year warranty.
