I like my WC snakes. I wouldn't worry too much, they are pretty tough little critters. The scars on a couple of mine are pretty good indication of that. I think the advice to keep the WC and CB snakes isolated is very good. I may be wrong (it has been known to happen), but I think the WC snakes would be much more tolerant of parasites, and also more adaptive to their environment with temperature control being much less critical than for CB (maybe just a basking light). I would think that if they will eat well and tolerate handling they should make a great pet. They can be released back in the wild. I have one gravid female (eastern) that I am planning to release after she has the babies (most of the babies too). Just keep looking and you should be able to find one. Good luck!
