Myles is a beautiful rat specimen!!
They really do have quite the personalities don't they? He may not like you reaching in for him because that is HIS home and he is protective of it and himself in there.
I strongly suggest putting newspaper down on your bed if you want to let him run around on it.....they could care less where they...well...leave a trail
Hope you have many hours of love and fun with Myles!
