And I just bought the fountain, 9 filters and a cleaning brush for $55* on Amazon. Love that place. I live within a mile of a fulfillment center, so things arrive very quickly. They could just about step outside, yell "Catch!" and chuck it my way. Lets see what these kitties think of running water that's not in my bathtub.
*The 9 filters cost a little more than the unit itself. There was someone else selling knockoffs cheaper, but several reviews said they weren't as high a quality, shed lots of carbon dust even when pre-rinsed and generally, weren't worth it.
