Dead Bat Found, No Explanation from Dog

Good ol' Saturday. One can clean, catch up on a couple chores, maybe start a project. In between laundry and dishes, I spied a small black pile of something on the first floor landing, under a plant. Upon closer inspection I see that it is a bat carcass. Husbear and I were out of the house for a long while on Thursday night, it may have happened then. If I was home while Pickles did his catch and kill number, I would know it. These remains could quite well have been there since Thursday night. Yesterday I slept late and rushed out the house for work, then came home and watched tv, certainly not looking in corners. Today I looked in corners.
