We discovered today, on our basement end table, a substance that is almost certainly mouse shit. Now Stacy is seeing it everywhere. She's on the floor with the baby and spots a small, black speck, "OOOOO! Is that mouse poop?"
"Oh c'mon," I implore, "not every small, black speck you see is mouse shit. That is exactly what the bat shit on our porch looked like. It's important to remember that all small rodents' shit looks the same.That there could be anything."
