IBD really isn't as prevelant as you might think. If you buy from a reputable breeder, you really don't have too much to worry about. Or from a reputable store like Kindra did, that's ok too - especially if the boa is older and you can observe it for awhile before buying, you're better off. Just do a strict quarantine for new boas and you'll be fine as long as you educate yourself about the source - that's the most effective way to avoid IBD. :gj:
Feel free to PM me for more details if you're really interested in a boa. ;)
