Kitty Litter Technology - Who Knew?

This last week in Juneau my hosts have been out of town and I'm house and cat sitting. I like cats including this one. My son's allergic to cats, so I really have been out of touch with the cat world.




So among my chores here - besides picking up the mail and the Full Circle Farm box today - is to feed Nori in the morning and empty the litter box at night.






The feeding part is pretty easy - though it means I don't sleep too late because someone is hungry.

But what were these huge flat burger like things in the litter box? And so many? I've taken care of my son's dog and know she doesn't poop that much or nearly that big. What gives?

Consider what a good cat litter should do: It should suppress odors, absorb, be biodegradable, nontoxic, and inexpensive. If you have more than one cat, both should be willing to use it. It shouldn't stick to paws, or between claws; yet it should clump enough to localize waste. And it's nice if it's flushable. But none of these features matters if your cat doesn't want to use it.

Now writer Curt Wohleber traces the design evolution of the stuff. Litter boxes existed before 1947. Owners had simply lined them with sand, sawdust, or torn-up newspapers. Then one of those moments -- like Newton's Apple or Goodyear's spilled chemicals:

Edward Lowe, back from the army was working in his father's supply store when a next door neighbor asked him if he had any sawdust for her litter box. [You can read the rest of this history at  John H. Lienhard's Engines of Our Ingenuity Episode 2103 or you can get the audio here.]

It took me a while to figure out that modern science now gives us kitty litter that soaks up the urine into these patties.

While I've been watching electronic technology, kitty litter technology took off.
