RE: What interesting things has your cat destroyed
Let's see!
My cat has destroyed more iPhone cords than I care to count. For some reason, those skinny white cords are his favorite thing to chew. He likes other cords too, but the iPhone chargers are his favorite by far. He's also chewed books, mail, and he is fascinated by anything plastic. We actually have to be quite careful, because if we leave any plastic bags around, or plastic packaging material (bubble wrap for instance) he will chew it up, swallow it, and make himself sick.
We're super cautious of this and hide away all our plastic bags for that very reason.
