Buyer's guide

Why a smart pet fountain?

Running water encourages cats to drink more. The smart part adds low-water and filter alerts, and some track how often your pet drinks.

Wireless pump or wired?

Wireless pumps are powered through the base, so there's no cord in the water, which is safer and easier to clean.

How often do filters need changing?

Usually every two to four weeks, depending on how many pets drink from it. The app reminds you.
