PETGUGU is a newer name in pet hydration, but the PF1 fountain targets a specific gap: data. Most fountains just circulate water. This one tracks exactly how much your cat drinks, down to the gram. It logs daily, weekly, monthly, and yearly totals through a companion app. You can share that account with a partner or vet. If your cat’s intake drops or spikes, you’ll know immediately. That’s useful for early detection of kidney or urinary issues. Just note it only works on 2.4GHz WiFi.

The filtration system is thorough for a unit this size. It uses eight layers, including activated carbon for odor, ion exchange resin for heavy metals, and mineral ceramics to add beneficial trace elements. The 2-liter capacity is fine for one or two cats. It cycles water reliably, and the pump runs quietly enough to keep in a bedroom. The fountain itself measures 9 by 7 by 7 inches, so it fits on most kitchen counters or corners without dominating the space.

The app is functional but not flashy. It gives you clear charts and alerts without unnecessary gamification. Setup takes a few minutes. The main limitation is the WiFi restriction—if you have a mesh system that forces 5GHz, you may need to enable a separate 2.4GHz band. Otherwise, it’s a practical tool for owners who want more than guesswork when monitoring their cat’s health.
