Cats are so different. Our current ones bring in so many little critters and let them go in the house, still alive, we had to close the cat door so we can check them before they come in. A past cat used to bring us paper and paper-like items, from food wrappers to people's junk mail, and one time the next door kid's report card. My wife's theory was that that cat thought paper things would please us because she saw us doing a lot of things with paper - we used to do a lot of printing. But I think the cat just didn't really get the whole hunting concept.
