So I've had my Boa Constrictor quarantined for about a month and a half now on a completely different floor from my ball python. Everything seems to be going smoothly, both are healthy. However, my roommate bought her own ball python and insisted on keeping him in the same room as my boa. I told her it wasn't a good idea because of IBD and all of that but she hasn't listened and decided to keep them in the same room . They've been in the same room for about a month now and her ball python is fine. Is this proof that my boa is not a carrier of IBD? If she had it wouldn't my roommates python be sick by now?
