Kat Lassie Can Haz Beverage?*:
Step 1: Lurk behind silly human, but don't look at the cup! If you look at the cup and they see you, they will think that "something is up."
Step 2: Look at person. Look at cup. Repeat. If you keep this up, they will give their tasty drinky-drank.
Step 3: If step 2 does not work, initiate the "tickle the face of the human with kitten whiskers trick." Humans love this and it will distract them from their mug of goodness.
Step 4: ATTACK! LICK UP AS MUCH LIQUID AS CATLY POSSIBLE.
*This works best when the mouth of the cup is wide enough to allow my big kitty noggin to fit completely inside.
