I swear that isn't the same chameleon!
He looks fantastic. So much better. Colours are good. He's not skinny, body tone is good. His chin is healing up. I wouldn't change anything with his cage set-up (lights, humidifier, drippers etc.). I think his eyes and casque are still slightly sunken but now that his burns are almost healed and he's got proper living conditions (humidity and water), that should rectify itself. Still keep the handling and interactions to a minimum until he is 100% and don't rule out that wellness check at the vets at some point. It's good to find out how he's running on the inside.
Keep up the good work. Your dedication to learning about chameleons and to Fred himself is commendable. Give him an extra housefly from me.
Cheers!
