New in box with collector's card. The Calendar Cats by Harmony Kingdom are a retired series of Pot Bellys. Mixing crushed marble with resin, they have the appearance of scrimshaw. The head comes off to reveal a small opening with a tiny mouse inside. They run 1 3/4 to 2 1/2 inches tall. At retirement several years ago, August was already sold out at the factory. We have quantities of almost every other month except October (sold out), November (2 left) and December (1 left).
