One of my cats learned to bump the faucet lever on the kitchen sink when he wanted a drink. Fortunately the sink only overflowed twice but that was enough to make me very serious about not leaving dishes in the sink.

Ours love direct from tap,but assumes the fountain is going to kill them.

Same here, we like our own furniture and faucets.

So the cats have their own cat towers and a water fountain. The first day with the fountain, the cats were so chill. I wonder if running-water sound soothes them.
