Saying they are ALL WC is a little over the top. I have seen some reputable breeders with CBB Savannah monitors. People in the US do breed them but the majority of them are WC unfortunantly.
Who breeds them?
I know people who claimed to breed them......but almost all of them are full of crap.
Sooooo, if there is a reliable source of captive bred savs in the U.S., please share with us the name(s).
