hi this is my first post. recently (the past month or so) my greek tortoise borris is trying to get out of his cage, and 5 times he succeeded. i just want him to be happy in his habitat! a few times a week i take him outside, and then hes happy and roaming everywhere. if hes been outside for like 1-2 hours, he just sleeps in his habitat. but if i bring him for less than that, he tries escaping. his habitat is a 4 ft by 2 ft under-bed storage container, with about 7 inch walls. i was thinking of maybe making a second container, then have a ramp for him to go to the other habitat. any help will be much appreciated!
