I got this fountain about 2 weeks ago and at first my little dog and both cats were a little bewildered by it...that is, until they figured out that it was for them.  I find that my pets are drinking more, which I am sure, is better for them.  The fountain was super easy to put together and runs so quiet that we don't even hear it.  I like that it can be taken apart effortlessly, washed in the dishwasher and the filter can be changed also.  This makes a nice gift for any pet lover.
