Hi, what is wrong with a tort roaming around the house? Mine does till I take it out in the sun. There's no other choice when one lives in a flat...one can't keep the poor thing "imprisoned."You will always get some to say go,ahead and others that say don't. The thing about why it's not a good idea, is because of the dangers for your tort. If you can build her a large outside enclosure, then, yes, take her outside, which is the best place for her and let her roam. If your talking about roaming in the house, bad idea because of the risk to your torts life.
