Comparable to king snakes, most milk snakes are tricolored (red, black, and yellow); but due to captive breeding they are now available in many color morphs. These snakes tend to be a more nervous type and, if startled, can possibly bite, or may urinate or defecate. With a lot of patient, gentle handling these tendencies will decrease. Milk snakes tend to be escape artists, so choose a secure cage.
A Milk Snake's life span is approximately 10 to 12 years. To help them live long lives in captivity, it is very important to provide these animals with a day/night photo period; 12 hours on and 12 hours off usually works best. The proper temperature for these snakes ranges from 84° to 92°F. These conditions can be best met by using a combination of fluorescent lights, incandescent lights, heat emitters, and under-the-tank heaters. Many of these come in a variety of wattages to accommodate different size cages.
