The PETLIBRO Cat Water Fountain offers a number of appealing features for pet owners looking to ensure their cats have access to fresh water. One of the standout strengths is the wireless pump, which eliminates the hassle of tangled cables and makes cleaning much simpler. The pump is still wall-powered, but this design choice improves safety and convenience. The fountain's 2.5-liter capacity is adequate for maintaining hydration, particularly for households with one or two cats.

A minor drawback is that the filters need to be replaced every two weeks, which could be an added maintenance task and cost. The fountain is not dishwasher safe, which means cleaning requires a bit more effort.
