I was a little worried that one of my dogs, who is very skittish, would be too hesitant to drink out of this fountain.  He loves it!  I honestly think he’s drinking more water (which he needs)!  I love how the fountain looks nice, stylish and isn’t plastic.  I also checked into the prices of the filter refills and was pleasantly surprised at their low cost. The whisper quiet feature is fantastic-by whisper quiet they mean practically silent!  The only complaint that I have is that a bigger size isn’t available (my dogs are big, so we have been refilling somewhat often).  Would absolutely recommend!
