Been explained time and time again. Those are their natural instincts. They don't like standing still water: potentially infected (reasonable in the nature), so they go for whatever is running, e.g. shower/tap as if it was a spring. They won't drink any water placed next to their food for the same reason -- in the nature it would've definitely be contaminated. You don't drink from a puddle next to your decomposing yesterday's pray.

So, a water fountain placed in a different room will solve all your issues.

I dunno about that guy posting about his cat ignoring the fountains and drinking from a puddle. The cat has an exquisite taste, what can I say.
