I live in central Ohio and am considering the possibility of tortoise ownership. I am willing to build an enclosure with indoor and outdoor housing and would like any advice on providing the best habitat possible. I think I would like an older sulcata, one that someone can longer afford or no longer want to take care of. Would it be possible to keep a sulcata if I build a large indoor enclosure for the winter in ohio? Do you use concrete for the floors in the indoor enclosure? My husband and I were wondering if we could use in floor water heat instead of a heat mat in the indoor enclosure? Also, any good ideas for an easy to clean water area for both indoor and outdoor enclosures would be welcomed.
