Call the scientists, we just figured out one of life's greatest mysteries. Why do cats like boxes? Turns out, it's in their genes. Big cats of all kinds have now shown they abide by the rule, "If I fits, I sits." Granted, there is a tad more box destruction with the larger cat models, but the natural attraction is there. It turns out the easiest way to trap a feline of any size is just to set down a cardboard box and wait. Curiosity will do the rest.
