Specific Dietary Recommendations -------------------------------- The variety of snakes kept in captivity is considerable, and their food preferences are quite variable. Following is a list of preferred prey animals for the snakes most commonly kept in captivity:** Boa constrictors, pythons, rat snakes, gopher or bull snakes: * Warm-blooded prey is preferred, such as rodents and birds. Juveniles of these species prefer the very small warm-blooded prey species. * They may also consume very small lizards and snakes. Some tree boas and pythons prefer lizards to mammals and birds. Garter snakes, ribbon snakes, water snakes, etc: * Fish, frogs, salamanders, toads, earthworms, slugs and carrion are preferred. * Many accept dead mice if they are covered with the external mucus of frogs or fish before they are offered. Indigo snakes, king snakes, and many racers: * Warm-blooded (mice, etc.) and cold-blooded prey (other snakes, lizards, etc.) are preferred. * The indigo snake prefers frogs but may eat anything when hungry, including dog or cat food. Ring-neck or brown snakes and their relatives: * Salamanders, earthworms, very small snakes and lizards are the foods of choice. Racers, vine snakes, coachwhips: * Lizards are preferred. Racers also eat mice and chicks of ground-nesting birds. * The young of these snakes eat large insects, such as crickets and grasshoppers. **Adapted from Frye, FL: Preferred foods of selected reptiles--the role of nutrition in the successful maintenance of captive reptiles. 86th Ann Sci Seminar CVMA, 1974, p. 5.
