By RTB, are we talking about true red tails or all BC subspecies? Does anyone know if there is a difference in the number of incidences of IBD in Hog Isles versus others? I can live without a RTB but I really would like to get a Hog at some point. BRBs and Rubber Boas are high on my wish list too but I may just stick with pythons . I find it interesting that Europe seems to have higher rates of IBD when it seems by the numbers that IBD originates in RTBs. Is this a fact or hearsay?
