The NPET fountain is made from clear, BPA-free plastic, allowing you to visually monitor the water level and water quality at all times. Its standout feature is its three flow modes: a standard waterfall, a bubbling fountain, and a three-way leaf design that produces separate streams. Owners can switch between modes based on what their cat responds to best.

The carbon filter paired with high-density cotton effectively acts as a pre-filter to catch hair and debris. Filters only need replacement every two months and are inexpensive. The fountain is easy to refill — just pop the top off and take it to the sink.
Assembly took a little longer than some others due to small, hard-to-read manual illustrations, but the fountain was up and running in just over three minutes.
