I don't have any tegus...yet. Still trying to talk the wife into another herp. I live in Southeastern Idaho. The winters are brutal with a lot of snow and they can be cold. Below zero a lot of the time. I'm assuming this is too brutal for tegus, but just thought I would ask. Also I've read a lot of authors stating that they just let their tegus free roam in their home. Is this normal? From what I've read tegus seem to act just like dogs, which would be awesome. Is this also the general consensus. Also by tegus I mean the Argentinian Black and White, which I've read is the most tame.
