Hint: not from their water bowl
  1. The bathroom sink
    They'll watch impatiently while I wash my face and brush my teeth and then get their heads wet drinkiyng from the running tap
  2. The bathtub after I shower
    All that yummy soap scum
  3. My bed-side water glass
  4. A vase with flowers
    Squishing their heads down inside
  5. Puddles
  6. The dog bowl
    But rarely their own bowl
