Puppies are born with incomplete digestive systems. They aren’t able to completely digest everything that passes through their digestive tracts. Therefore they recycle, and pet owners can’t stand to watch that kind of natural recycling.
The Associated Press, Reuters, MSN and CNN and a couple of other media sources that come to mind are kinda like that, too, but they are not puppies and so far there are no products available to prevent them from recycling their own crap.
