Hey Nick,
That's really great news. For what it's worth, my daughter did a science fair exhibit last year on snake movements. She compared snake movement patterns in water, on carpet, on coarse kitty litter, and on cardboard, and she found that coarse kitty litter provided the most naturalistic movement patterns. If you were really curious about your snake's movement patterns, you could spread some in a box and watch your snake crawl around on it.
Also, it might not be a bad idea to supplement your snake's diet with reptile vitamins or 10% Pedialyte in its water dish to provide more nutrients (Calcium, Magnesium, Sodium, etc.) during recovery. You also might consider a higher protein diet during recovery, but I certainly understand sticking with what's working
. Cheers,
Rick
