The rat snake is a non-venomous snake found primarily in North America and parts of Asia. Known for its slender body and long length, it can grow up to 8 feet. Rat snakes are often recognized by their distinctive coloration, which can vary from black to yellow or green, depending on the species. They are excellent climbers and are commonly found in trees, fields, and near human habitats. These snakes primarily feed on small mammals, particularly rats, which is how they got their name. Rat snakes play a vital role in controlling rodent populations, making them beneficial for agriculture. They are generally docile and pose little threat to humans, often opting to flee when approached.
