Hi, I am interested in owning a sulcata. I live in Indiana where it can get really hot and humid in the summer and very cold in the winter. I wondered what your advice would be for housing a sulcata? I share a house with my parents and they would not want a huge tortoise roaming in the house, nor would they want him to take over the lawn. I wondered if I could construct some kind of outdoor pen that I could fill with substrate to where it wouldn't burrow into the lawn? What kind of size of an enclosure would I need to prepare for a full grown tortoise? And since it gets very cold, I may be able to make space for him in the basement/crawspace as well, although sometimes mice and spiders can creep into there. Do you have any ideas how I might be able to make this work? Thanks!
