I have a friend who found a desert tortoise that was obviously a pet roaming thru her yard trying to get in the fence and then followed her around so she kept it and obtained a permit but now she can't get a hold of anyone to answer her questions. she has a 12x12 fenced area for him and he's taken to sleeping by the house in an old dog house. he eats alfalfa and green leaf lettuce kale zucchini and sometimes green beans. is this the right diet? also dusted with reptivite or calcium without d3. should she be feeding him anything else. its already been getting pretty cold at night so he sleeps in the laundry room then goes back out during the day. what is the best way to set up his enclosure? also what exactly do you do for hibernation and when should it start? the only answer she's been getting when its extremely cold put him in a box with hay and waits til he wants to come out...... she wants better info than that. Also he's pretty big, about 10-12 lbs and 10-12in across.
