Smelly Sneakers.
I had an interesting problem back in April, where for so reason my sneakers smelled like cat piss. That is what one particular inmate would say every time I walked into the small TV room. They did smell a bit but it was more mildew than anything else.
No, we do not have any cats around here. They do in some of the maxes to keep the mouse population down. Anyhow, I think the inmate that was razzing me put something in my shoes. He is now gone I have washed the sneakers out, and no more strange smells.
