Smaller tortoises can be kept in 8ft X 4ft (244cm X 122cm) enclosures. Permanent enclosure sides should be at least 12 inches (30 cm) higher than your tortoise while standing on his hind legs. For tortoises that are expected to get large as adults, they need more space and higher walls.
Tortoises do not smell bad and they don’t have much of a natural odour. At most, they may smell musty or just have an outdoorsy, musky smell. However, their enclosures can sometimes become breeding grounds for bacteria and other odor-causing organisms if you don’t clean them well enough. A stinky tortoise could be a sign of infection or illness.
