A certain type of cat whose fur can be used to achive a hullucinagenic state when smoked through a pipe. These cats are generally found in the greater Maine area, and are large and oderous. The discovery that these cats could actually be smoked was discovered by Sam "The Cat Smoker" Jenkins, when he mistook a calico cat for a cigarette.
While some prefer smoking cigarettes or other tabacco products, I distinctly prefer tokin' a calico.
