Overview
The Brook Glass Pet Fountain holds about 90 ounces (2.7 liters) in a bowl and fountainhead made entirely from food-safe, lead-free glass, borosilicate for the fountainhead and tubes, soda-lime for the bowl. At 6 pounds, it's noticeably heavier than most plastic or steel fountains, which helps it stay put once it's filled.
It runs on a 5V pump (model SMA-800) with three flow intensity settings, low, medium, and full, plus swappable flow reducers, so you can tune the stream for a shy cat or a big dog. Filtration comes from a reusable carbon filter basket paired with a particle filter, and the whole unit is listed as dishwasher safe.
At $89.95, it costs several times more than plastic competitors in this category, which puts it firmly in the premium tier. It ships with a spare tube, cleaning brushes, and a silicone cover you can use to block the built-in light if you don't want it on.
