PETLIBRO has carved out a niche making smart pet gear that doesn’t feel like a gimmick. The Dockstream 2.5L is the rare water fountain that prioritizes data over design fluff. Its core appeal is the PawSense Health Monitoring System, which tracks exactly how much your cat drinks, how often, and at what times. That information surfaces in the app as clean, readable reports. It’s useful for spotting changes in behavior that might signal a health issue before it becomes obvious.

The fountain holds 2.5 liters, which is enough for multi-cat households or a few days away. Water flows quietly over a multi-stage filtration system that catches hair and debris. The app lets you set a hydration goal for your cat, then shows you progress toward it. At 9.1 x 7.5 x 6.3 inches, it fits on most countertops without dominating the space. The WiFi connection means you get notifications if the water level drops or the pump needs cleaning.

One honest limitation: this is a fountain that rewards attentive owners. If you’re not going to check the app or act on the data, you’re paying for features you won’t use. The plastic construction is sturdy but not premium. Still, for anyone who wants to understand their cat’s drinking habits at a glance, this is the most practical option available.
