virtually no one sells CB savannahs. there's too much imported babies to even make it worth your while at all. i know of 1 or 2 private keepers that do it, i dont know there names or anything though.
WC means wild caught. It means your monitor could be infected with all these parasites, and it means it probably isn't healthy. Go for a CB Ackie or Blackthroat monitor if you want a happy healthy monitor.
