They Came At Night

you and your friends enter the cabin. there is an eerie atmosphere and a vile smell coming from the attic. however, it seems to have been built recently, as the wood is not rotten at all. there are a few beds here, and they are all clean, a fireplace with plenty of wood and a fridge labelled "Meat". 2 of your 4 friends want to check out the attic. what do you do?
