recently me and my mom went to go get some dog food at a local petsmart. I happened to look at the little area near the reptile equipment where the live reptiles are being held. generally this store takes okay care of it's animals, but this time a saw a little baby veiled chameleon for sale. He/she was so tiny (barely a couple months old) and I couldnt help but notice one of it's front legs twitching like crazy. He/she looked pretty healthy for it's age. Is this some sort of disorder?
