I got this for my finicky feline.  We recently lost a pet and I noticed the current water dish gets slimy even just after a day.  I know it has to do with my environment as well.  But lets face it who would want to drink stagnant water even the same day.  This fountain came at perfect timing.  Set up was a breeze! The water movement is perfect not to my fur baby anxious or nervous.  The only downside is if your house is quiet you will hear the trickling of water until YOU get use to it.
