The grey rat snake (Pantherophis spiloides), also known as the central or midland rat snake, is a non-venomous constrictor native to the central and eastern United States. These snakes are excellent climbers and are often found in forests, farmlands, and even suburban areas, where they help control rodent populations. They have a distinctive greyish body with darker blotches running along their length, providing effective camouflage against tree bark and rocky terrain. Gray rat snakes are primarily nocturnal hunters, preying on rodents, birds, and eggs, which they subdue by constriction. Despite their large size—often reaching 4 to 6 feet in length—they are generally docile and will typically freeze or vibrate their tails when threatened rather than attack.
