Between blotch and blok

So, before it joins the list of things to Freecycle, would anyone reasonably local like our Drimkwell Mini pet fountain (comes with no pets!)? Socks took to it instantly, but once Little used it it became entirely hers and almost certainly extended her life--but the boys have rejected it since her death. I've cleaned it, so apart from the odd bit of limescale, it's neat and tidy and only requires the purchase of a new filter (I seem to have used our stock up).
