switch over to newspaper, soak him/her is some warm water for bout 15 mins, and if you got a local reptile store, you can get wats called Mite Off, My Ball Python was a Wild Caught, and she came to me with mites, was a pain but a month later, mite free. If thats your issue, but yea make sure that the temp where your BP is hiding is the temp of the reading your getting. As far as activity, mine is a bum. haha. I dont know how old yours is, mine eats two adult Mice. to get full. Might try and feed it again. The reason for the newspaper, allows you to clean the cage easy if you have mights, and allows you to see them alot better rather than them hiding in the bedding. Let me know if this helps. good luck. best wishes.
