He will figure out what he needs as long as you offer him the opportunity. Pretty much all my snakes prefer their cool sides of 80 over their hot sides. Tonight is the first time in about a week I caught my Colombian BCI girl under her RHP coiled up and she ate a rabbit 3 days ago. My sunglow girl went under her CHE for about 10 mins after eating a rat and that was the first time in about 2 weeks. And my BP, well she has been on a hunger strike for about 3-4 months so she pretty much lives in her cool hide during the day and comes out at night to destroy as much as she can before 7am hits when she goes back into her cool hide lol.
