I have three gulf coast toads in my classroom. Now that it has gotten colder here, they spend most days hiding under their logs, burrowed into the topsoil. My school building is not heated at night. On cold mornings, before the timer lights kick on, I usually find one or two soaking in the water dish. Once the tank heats up to around 75, they climb out and go back to the log.
Is this normal behavior?
