Kitten Mittens, also spelled Kitten Mittons by Charlie due to his illiteracy, are a cloth footwear made specifically for cats. The goal is to make them quieter when they walk around. They are first mentioned in the Season 5 episode "Paddy's Pub: Home of the Original Kitten Mittens".
Kitten Mittens are "great for cats that are one legged, fat, skinny, or an in-between."
They were part of The Gang's effort to sell merchandise related to Paddy's Pub, but a contract they signed without reading it gave The Lawyer 100% of the rights to Kitten Mittens and all the other merchandise they had created.
