Behavior
The eastern rat snake is primarily active at night during the summer, and diurnal in the spring and fall. It is a terrestrial burrower and an excellent climber, and it may enter water. Eastern rat snakes brumate in colder months. Brumation is similar to hibernation — it allows the snake to be mostly asleep, but still wake up for occasional activities, such as drinking water. Rat snakes emit a foul-smelling odor when they feel threatened by a predator. This musk imitates what a poison would taste like. Eastern rat snakes are constrictor snakes and will use their body to suffocate their prey.
