In California and now, in Arizona, there are stringent laws concerning the wild collection and the sale of captive bred kingsnakes about which many pet stores are unfamiliar. Captive breeding has produced numerous color and pattern morphs, ranging from different types of albinos to striped and mottled markings. Some of the most striking, however, are the most natural - vivid bands of colors, or the simple black and brilliant yellows of the Florida and Sonoran kings. Kings are oviparous, laying fifteen or so eggs. Hatchlings emerge from the eggs anywhere from six to ten weeks after being laid, and range in size from eight to thirteen inches long.
Adults range in size from three feet up to seven feet, depending upon the species.
With proper care, kings will live 20 or more years. What subspecies you select is a personal decision, but the criteria by which you evaluate the potential purchase remains the same. The snake should have a firm rounded body. The skin should be shiny with no sign of sores, scabs or discolored patches. There should be no swelling either above the vent or towards the tail.
