The Western Rat Snake, also known as Elaphe obsoleta, is a non-venomous snake found primarily in the central and eastern United States. It typically grows to lengths of 3 to 6 feet and is known for its distinctive coloration, which can range from black to gray or brown, often with lighter patterns. This snake is an excellent climber and is commonly found in forests, fields, and near human habitats. Western Rat Snakes are constrictors, meaning they subdue their prey by wrapping around it and squeezing. Their diet mainly consists of small mammals, birds, and eggs. These snakes play a vital role in controlling rodent populations, making them beneficial for the ecosystem.
