Rock Stars

I was watching the reptoid featured movie "Rock Stars" this morning, looking for the shifts and such. A thought occurred to me after seeing one scene with burnt toast and coffee. Do reptoids eat and digest "human" food? I know they prefer blood and babies, but I wonder what effect meat and potatoes has on their digestive tracks. I also wonder if that has anything to do with them staying thin.
Something else I noticed when movies try to manipulate my emotions..the chills I feel start in my lower body.
