My russian has been fairly active since I got him, he would walk around then head to the corner of the room to sleep, then I would put him back in his habitat, just this morning, after he woke up he wouldn't stop moving, and it's not just cruising, he would sprint non stop. It' been 10 hours and he won't stop. I understand that they are active and I want him to be active and healthy, but this is such a dramatic change that I'm concerned that something is wrong, or that I did something wrong.
