Well, I've often seen a cat without a grin,' thought Alice, 'but a grin without a cat is the most curious thing!' We don't know what Lewis Carroll was drinking when he wrote Alice in Wonderland, but we're pretty sure it wasn't tea or coffee. From the Caterpillar with the hookah to the Mad Hatter, his characters were as "out there" as Carroll himself. The Cheshire Cat Mug celebrates one of our favorite Wonderland characters. Pour any hot liquid into this mug and the cat disappears, leaving only his famous grin! It's guaranteed to leave a smile on your face, too. Holds 12 oz. of coffee or tea or whatever it is you drink. Disappearing mugs are not dishwasher safe.
