Kyoto does that with out bathroom tap. We then bought her a cat fountain. She's also the one that pesters for dreamies. Whilst the other's quite like them, they await her pestering.
She'll sit in front of us staring at us, not moving. If we ignore her, she'll start tapping our legs. If we carry on ignoring her, she'll either jump on our knees, stick claws in our leg, or come up close and tap our faces. This goes on until we get up, go over to the cupboard and get the packet out. This is where, out of thin air there are now 3 or 4 cats there sat waiting for Dreamies.
