Good! it sounds like you are making some progress! I wouldn't worry about the pooping thing. One of mine (Melony) goes to the bathroom immediately after coming out of her viv almost every time. Shes a lazy one though, and even at night only makes 1 or two laps around the viv before going back to bed. I think that when she comes out she starts moving around more than usual and that kind of "loosens her up," so to speak. Anyway, we just usually make sure we have a paper towel handy to catch her little mess as soon as she starts making the motions to "go." We're hoping she'll outgrow this, lol.
I'm glad things are starting to work out for you, Ocelot. Just keep working at it, I'm sure you and your little snake will be buddies in no time!
