The weirdest part is he doesn't seem to be using his right front leg when he does move himself. His heat bulb recently went out for a day or 2 until I could get a new one and replace it. Now the middle of his cage reads 82 degrees. I was thinking this is just brumation possibly due to the few days of colder temperatures but the not moving his leg got me questioning. Let me know what you guys think thank you!
