i have given nellie two smaller prey items in one feeding before by putting the head of the second one against the butt of the first one as it is being swallowed like blink said. it's really not difficult at all once you do it the first time. the only reason i did it though, was because i knew the prey was too small but it was all the pet store had at the time. i figured it would save her energy on striking and constricting and starting the whole swallowing thing over again if i just gave them to her head to butt. it worked well, but i probably wouldn't want to have to do it every time if i could avoid it.
