Cat-Foiling Beverage Device

The cat likes to drink out of my water glasses. She has plenty of her own water, it's just a little thing she likes to do.  If the glass is full, she sticks her head in and sips delicately. This bothers me a little.  If the glass is too empty or too narrow for her to reach the water by sticking her head in, she dips a paw into the glass and licks the water off it.  This bothers me a lot.

So, for those times when I can't keep an eye on my water glass and repel any little furry invaders (such as when I am sleeping), I have invented the Cat Foiling Beverage Device.

Genius.  I haz it.
