In herpetological terms, a pinky is a newborn, (1-7 days old) mouse, usually a staple feeder for smaller colubrids or
baby constrictors, or as an occasional treat for bulkier lizards such as blue-tongued skinks. Pinkies are
cheap, anywhere from 25 cents to a dollar, and are best fed live, for their movement attracts the
animal, and they aren't harmful yet.
