O.k. so, I dropped a (supposed to be hopper) It didn't hop, seemed like a regular mouse to me, in with my baby ball. So I know it was starting to get hungry, was on the prowl the last two nights. But I heard some commotion in the back of the tank (blind spot), but a few minutes later I saw the mouse again. Some more time went on, then another commotion. Waiting, looking, no sign of the mouse. It was maybe only 15 to 20 minutes since I saw it last. There is a possible mouse sized lump, but hard to tell, hes all curled back up and comfy looking again. Could he have woofed it down that fast?
