Our cat just liked the smell of the grease (soaked bag), she'd nibble on a french fry and spit it out. But the bag they came in, especially something like 5 guys? She'd sit in that bag for a week straight purring away. Pizza boxes were a similar favorite of hers, she liked the cheese and meat toppings but wouldn't touch the rest. But she's sit on or in a box like it was the best cushion.
