Paper towels, easy to clean, holds moisture, and makes feeding a breeze. But what about burrowing? I would switch to coconut fiber but my frog is doing so well on paper towels, eating 4-5 medium/large crickets per day and he's just a little bigger than a quarter. What are your thoughts?

Also, he's in a plastic tub with a pothos vine cutting for added security. I replace the paper towels daily or when I see that they have been soiled.

What is the purpose of burrowing behaviors? Thermoregulation? Sleeping?
