When I bought that first pet fountain back in the winter (on sale of course) I thought it was just me wanting fancy things for my cats. You know how that goes, you spend a bunch of money on a fancy toy and they play with the box right? So I wasn't sure how well the fountain would go over. However after a few days they LOVED it and didn't really want the regular bowl. The problem is now that it's been so hot out here, they keep draining the fountain too fast. I decided I should upgrade to the biggest size one they had. lol

I figure if my 7 (8 when I got the fountain) cats loved it that much despite having different preferences with most anything else, then it must be a good thing.

If you get one, stick with the Petmate one. There is a cheaper version out there (can't remember the name brand) but insead of a gentle slide for the water to go down, it just sorta drops off the end. I'd imagine that kind would be noisier and possibly splash water out of the bowl, although I don't know that for a fact though. This Petmate one is quiet and doesn't splash.
