A water-fountain for cats (Kingsway CB4)

Bought maybe 8 years ago. Our cat was not interested, so the thing went in the garage. It should still work (it worked fine when we put it away). Needs to be plugged in to work, though, which is the other reason (besides the disinterest of the cat) why we stopped using it. You might want to change the carbon filter (it looks good to me, but it has been sitting there for ages).
