"Or changes the dang cat litter."...Now that is a decidely unpleasant aspect. Take, instead, rabbits. Rabbit "output" is beneficial to the environment and gardeners love it.

Yeah, The rabbits recycle, too.

"Yeah, The rabbits recycle, too"

Just read an article that rabbits are born with the ambition to die, and it is the rabbit raiser's job to thwart that ambition. SO: It's a good thing they do recyle - tho' not always as easily as one would presume . . . In terms of I/O, and the usefulness of the O, they are one of the most efficiently designed biological systems I have heard of. (Provided they live, or die in a manner to be recycled).

It's a good thing Schroedinger's example was a cat. Would hate to see a cute bun-bun in a complex function of alive and dead. They would tend I guess to the dead end . . .
