Another Poop Post

I know I said I'd never write about dog poop again, but I have one thing that keeps nagging at the corners of mind now that summer is here. Have you ever noticed how dog poop turns white after it has baked in the sun for a few days or weeks? Isn't it strange how it's the only thing that turns white after baking. Everything else on the planet (at least, everything that I can think of) turns brown from baking (or black if it's in the oven too long). I've even seen fox poop on the sidewalk for days and days and it doesn't ever seem to turn white. But dog poop does.

I find this phenomenon very interesting and I find myself wondering if the poop would turn dark again if I rehydrated it.

Can anyone tell me? Or should I just stay out of the sun.
