My wife has, on two different occasions, bought china teacups at a thrift store, and dropped them getting out of the car in the parking lot when she got home.
That’s good theory. Packaging, above almost anything else*, is the rightful property of the cat. And cats know it. And, as you must certainly understand, defend their prerogatives energetically.
The other theory is that the cat did it in pre-emptive self-defense, because Shakes is a mean drunk and the cat just doesn’t want to put up with it. But I don’t favor that theory. It assumes facts not in evidence, and the “you threw away MY package” theory is both sufficient and fully supported by the known facts. Occam’s Razor and all that.
*The only things higher in priority in the “rightfully the cat’s” list is canned seafood and catnip. And any pillow.
