Unless it's my cat. Got heavily filtered water and use it to fill 3 different fountain bowls in different parts of the house (none near the food source, but I did that because if they are, she'll eat her food over them...) and the cat still demands I turn the sink on instead. Same exact water, and even though I change her water out almost every other day, the sink wins. Just glad she hasn't figured out how to turn it on yet...

Funny enough the last fountain I got looks like a faucet and she's like "nah I'm not stupid, turn the sink on."
