As stated I won't feed live , he hasn't been fed live before for the first six months of his life so I don't see a need for it now but thanks for the advise .
His bedding isn't dirty as he hasn't done anything since I've had him...I did leave the rat to warm up on his viv for a few hours already but he doesn't so much as poke his head out! As I've said I never see him! Next week I will leave the rat in over night, and I won't handle him or move him in the mean time and see what happens next week!
Thanks again
