There are several theories as to the origin of the phrase "grinning like a Cheshire Cat" made popular by Lewis Carroll when he authored Alice's Adventures in Wonderland (published 1865), but no one knows for sure. One conjecture is that because Cheshire was a dairy community, there was an abundance of milk and cream to keep all of the cats in town fat and very happy! But I disagree! After seeing Cheshire Cat from Just Inklined, my personal opinion, which I am certain you want to know, is that the cat had strutted his fat self within inches of a dog secured by a chain and then thumbed his nose! The Cheshire Cat is just very proud of himself for tormenting a dog!
