Elvis is an adult male. Last weighed at around 12lbs. I adopted him on November 1st, 2020 and was not really prepared with my enclosure. He wasn't exactly lethargic yet, but I allowed him to soak a bit and he was able to defecate before boxing him up and putting him in a dark corner of my garage. I live just east (18 miles) Los Angeles, in the low hills of Whittier. The outside temps at night have been mid to upper forties, but my garage seems to hover between 55 and 60 degrees. Some times we will disturb Elvis when looking for tools and he'll hiss. And I have taken him out once (late January) to weigh and make sure he isn't burning to many calories because of the temp in the garage. He seems really healthy. I've read that he should only hibernate for approximately 120 days, but I'm thinking that's arbitrary. Should I bring him out 1st of March, or just wait until he gets really active and lets me know it's time? Second question, my enclosure is about 120 sq. feet. I would love to get a 2nd tortoise but I've heard that mature tortoises can be territorial when it comes to other males that they did not grow up with. Or, what about the mixing of tortoise species? Can you tell I'm new to this?
