I bought these chameleons at Petco. They where about an inch big when i bought them, which i personally feel that is wayyyy too small and young to be sold at. My boy, Charlie is about 4-5 ish months old and so is the girl, Peaches. but when i first bought them, Charlie was a beautiful pastel green and blue, and Peaches was black. Peaches is a lighter color after we bought her, but shes just very off balance. she loves being held. every time i open the cage she runs to my hands. but when im holding her, she falls alot. she also tries to reach behind her as if shes trying to stretch. she doesnt eat as much as the other. she has just started to become off balance. Is she sick?
