My deceased cat would drink from a glass only, and only Evian (tap water was being ignored), and only if the glass was on the coffee table. She drank more than a glass a day but she had kidney problems.

My cats drink from the dogs bowl, so I don't really know. I only know that they spend a lot of time there sipping. In the summer they only want to drink rainwater which we collect outside in big cans for watering the garden. In those month I can't get them to drink tap water.
