Chessie or other wise known as the Cheshire Cat in most Alice in Wonderland related media.
Alice Adventures in WonderlandEdit
During Alice's first visit to Wonderland, he was the pet cat of the Duchess and was very fat. He later followed Alice, asking where the Duchess' baby had gone. Alice told the Cat that the baby had turned into a pig and ran away. The Cheshire Cat disappeared briefly before coming back to double-check her answer, as he thought Alice had said "fig" instead of "pig." He also told Alice about the Mad Hatter and the March Hare, and pointed where they lived.
Alice, who was not at ease by the Cheshire Cat's sudden disappearances, asked if he could do it slower. The Cat did as he was asked, disappearing bit-by-bit until all that was left was his smile. Alice responded to this by remarking "I've seen a cat without a grin, but never a grin without a cat!" before the smile disappeared. His head later appeared during the Queen of Hearts' croquet game to cheer up Alice.
The Queen ordered the Cat to be the decapitated, but the Executioner argued that he could not because the Cat lacked a body to decapitate. This led to an argument between the Queen, the King and the Executioner about whether or not a disembodied head could be decapitated. The Queen ordered that the Duchess should deal with the Cat, as it was her pet, and let her out of jail. After the Duchess took Alice to see Gryphon and Mock Turtle, the Cheshire Cat was not seen again during Alice's first trip and never made an appearance during her second trip. However, it was believed that the Cheshire Cat made other appearances in unrecorded trips to Wonderland.
