This is a pretty decent fountain. I’ve had others in the past and this is def one of the best I’ve used for my 2 cats and kitten. It seems to work well with their 3 different sizes. Took a little while for them to try it cause they seemed scared at first. The pressure is just enough and cleaning and changing the filter is as simple as all others have been. The replacement filters from a search are also in a decent price range. I gave it 4 stars due to the cord being super short for the area I have their food and water so I have to use a long extension cord which is annoying but also not a deal breaker.
