A dead mouse, that’s what! In fact, I found two of them. I was cleaning out the garage and returning about 20 bags of bottles and cans for a whopping $20 when the guy at return depot pointed out the mice at the bottom of bottles. I still have the bottles in the garage because they wouldn’t dispose of the bottles because of the mice. Maybe I will take a picture and post it. What we figure happened is mice went into the bottles to lick up the juice and then couldn’t climb out. Dumb asses!
