I have just been approved to adopt a desert tortoise. I think he/she will be approximately 4 years old. The tortoise has spent his days outside (Thousand Oaks area) and nights indoors. I live in Agoura Hills (45 minutes NW of Los Angeles). I have built a 4'x8' predator-safe outdoor enclosure. I'm wondering if I need to transition slowly to the outdoors overnight or can I immediately let the tortoise stay outside? I have build him a dirt/rock burrow (which I'm sure he will alter) and provided a little wood structure/burrow. I'm also wondering if there will be any issues of him being alone? He is currently with 5 of his clutch mates, and has been with them his whole life. Oh, and he has hibernated safely every year of his life. Help for this newbie, please! Thank you.
