The Squirrel Coffee Cup is clearly not made for humans. Although the reasoning behind such a creation may not come easily to some, Archie McPhee, the online store carrying the mini mug, writes, "As you sit down for your morning coffee, have you ever considered sharing with the squirrels? Just pour a little hazelnut coffee into [the] Squirrel Coffee Cup, set it down on your window ledge, and wait for a squirrel to come and enjoy it with you." This is definitely one way to see such a critter up close and personal.
Made out of porcelain, the Squirrel Coffee Cup is also being touted as the world's smallest coffee cup. Considering that it is made with squirrels in mind, that only seems natural.
