First off, I don't know what you must be going through politically or militarily, but you and your fellow countrymen are in my thoughts. As for your choice to keep this animal alive, I wish the best of luck! It will not be easy, as I'm sure you know, but as you figure out what actions trigger eating and drinking responses, I hope it will get easier. If you are successful with all your efforts my advice would be to keep this little one in a smaller than normal enclosure and be very careful with basking site temps. Not sure if he will be able to self-regulate temps as well as sighted chameleons. Also, I would not make any changes to the vine placement once it is set up. This should make it somewhat easier (in theory) for him to get around.
