I don't keep any sulcatas or leopards, but I have been pretty fascinated them. In Canada the climate is very "tortoise un-friendly", but if you try to replicate their natural enviroment as much as possible when they're indoors, will they still breed? To give you an idea of what I'm talking about, let's say say we keep some Geochelone pardalis babcocki in a 3m x 3m indoor pen, with a 3m x 3m indoor grazing area, and a 7m x 4m outdoor pen (when the weather allows). They're mainly indoors, but their pens are carefully landscaped to match their natural habitat as much as possbile. Would it be possible to breed them under indoor conditions? I've been pondering this for a bit.
