So I'm reading one of the reptiles magazine articles on housing GTP's, and it says juveniles can be started in an enclosure that's 12"x12"x12", and eventually moved to a 24"x24"x24" or 36"x24"x24". Can they really be started in a 12"? I'm obviously just beginning my research but do have a 12" cage available if that's large enough for a juvie.
