Great job! It is such a relief when we find a solution for a snake that was obviously uneasy or not comfortable. Seeing them get relaxed and cozy is a wonderful feeling.
Just as an FYI - I'm a big fan of multiple hides for my snakes. Full hides, cork rounds, sky hides (attached to the top of the enclosure), Magnaturals rock caves held by magnets to the sides of the enclosure - most of my snakes seem to appreciate and use all of them. I guess it boils down to them being happiest when we can offer them the most choices.
