I thought I QT'd Duma for three months but turns out it was two, need to pay more attention... Basically I just spend the first few months of QT watching the snakes behavior. If something seems off, they stay in QT. I like to make sure they poo, urate, and eat okay before considering putting the QT'd snake with the rest. I'm keeping cupcake QT'd for 6 months. Everyone has told me that pythons die very quickly when they get IBD, so if cupcake has it/transfers it to my collection, I'll know fairly quickly. Basically once cupcake is in with my collection, I'll get my Kahl from my aunt and keep him where Cupcake was kept. I have room to QT both of them, but I paid a lot of money for him... NO WAY IN THE WORLD I'm risking that.. Since the head wobble thing I've been very very cautious about QT. No one in my room, if I need to handle my snakes, I do it before I'm near cupcake, then I move onto cupcake. Once I'm done with her, I shower, throw my clothes in the washer and grab some new clothes, and I still don't go around my collection until the next day. It's not something casual. Whether or not anyone thinks I'm a responsible keeper, I'm not dumb enough to expose my snakes to something like a possible case of IBD.
