This water fountain is 'purrfect'. Very easy to clean, assemble/disassemble....for cleaning, the pump is especially easy to semi take apart for cleaning....important in my area where we have hard water and get scale build up. It's robust, holds lots of water, filters are easy to replace. But most importantly both my cats love it and freely drink from it. One thing though I had to remove the 'daisy top' as they wouldn't drink from it with it in...works perfectly without.
