1) I know that cages made of cedar are really bad for monitors. Can one safely build a cage out of yellow or white pine? Would the oils in either of those woods hurt the lizards?

2) These cages are for two savannah monitors of opposite sexes. How do I introduce them to one another? How big would their cage have to be for them both to be comfortable? To breed? The female is a bit larger than the male. Will that be a problem?

Thanks.
