Hmmm, the guy at the reptile store told me boas aren't like ball pythons and have no problem being in big enclosures. To answer your questions, the boa is a little over 2 feet long and I've had her for almost 5 months. I feed it fresh killed pinky rats. The only other time I've had a problem with feeding was the last time she shed, so I'm assuming that's why she refused the last one.
