wow, its hard to believe that animal is a year old!! it still has its baby colors. Good thing you brought him/her home. Hopefully you can get some weight on it. If it hasnt been fed on a regular basis i would be careful not to feed it too much, you might shock his system. I would offer a couple crickets per day, or every other day until you can get some meat on his body.. i certainly wouldnt offer mealworms yet. Be sure and offer a small dish of calcium powder, perhaps it will eat some for you, and dont forget a little water bowl too. I would also remove any substrate and keep him/her on paper towels or tile, something he/she cant ingest. Again im very surprised that animal is a year old, holy moly! If nothing else at least the owner had some sense to get rid of it before it dies! good luck with it.. seems to have some really nice coloration
