I had a plastic bag on top of the fridge like one of the small ones for sandwiches and my cat ate 1/3 of the bag. She's a big cat like a little overweight so should it just pass through her or are we going to have to take her to the vet? She's not acting weird or anything she's sleeping but she always does that lol. I woke her up to check on her and see if she's ok and she's acting normal.
