After weighing whether to let our 2 juvenile DTs roam the entire back yard or keeping them in their current 30 sqft enclosure, we decided instead to find a spot for a second enclosure so each can have his/her own turf. We're toying with the idea of a long skinny one that goes along our concrete wall -- that's where our torts spend all their time when allowed to free roam anyway. It'd be 80% in deep shade from jacaranda and ficus trees, with strong morning to midday sun in one corner. Are there any disadvantages to doing that? I think it would end up being about 3x20, and would be for a rambunctious 6 inch male (we think).
