The Big Max pet fountain from Pioneer Pet is an attractive, easy to clean, large capacity drinking fountain that will help your cat drink more water. This is one of the largest capacity pet drinking fountains available, so your cat will always have plenty of fresh drinking water to keep her hydrated. The Big Max only has a few parts, which makes is very easy to clean.
I have the stainless steel version of the Big Max and I like it a lot. It really is easy to clean with just a few parts and it holds enough water for multiple cats. The inner parts housing the pump are still plastic and do need to be carefully cleaned, like any fountain, and if you have hard water, it will take a little extra effort to remove the mineral build-up.
Available in black or white ceramic or stainless steel from Amazon
