Blackmoor Vituperative

If you have a cat fountain, please keep it clean. You must disassemble and clean the fountain, including the pump, every time you refill it with water. Every. Time. That means taking the little magnet impeller out and cleaning that (including the hollow center of it — use a pipe cleaner or a very thin brush), and the hole where the impeller goes in the pump. Clean EVERYTHING, EVERY TIME. If you don’t, slime and junk will build up, which is bad for the cat, but will also prevent the pump impeller from spinning. I really can’t stress this enough: disassemble and clean EVERYTHING, EVERY TIME you refill it.

I also fill the fountain with a diluted bleach solution and let that soak, every month or two, just to thoroughly disinfect the thing (and then rinse it a dozen times before setting back out for the cats). Some people use vinegar; I prefer to use bleach for that.
