hey hc.......jim k here....jason is right.........get a book that covers these guys. i have used the audubon field guide for reptiles and amphibians for years. they have a great section on whiptails. mine were the giant, marbled and checkered whiptails and were trained very easily. its been many years since i had those. would like to get some more one day but you don't find those around st. louis, missouri.............
good luck
