  Rowdy will do that (not the shaking part) but not wanting to sleep with us when he doesn't feel good.  At least that's what I attribute it to.  Sometimes when this happens, I will notice a loose stool or I will find some throw up, but sometimes, I don't have any visible signs of not feeling well, except for not wanting to sleep with us and sleeping more during the day.
