Yeah, creatures trapped in a metal box gets ugly, fast. I once worked for a grocery store cheap and poorly-run enough to use live-catch mousetraps (because they could be reused and were more effective than kill-traps, which often just result in your store being full of lame or tail-less mice that eat pretty much as well as healthy ones).

The contents of one of those live traps after having been left for too long with multiple mice inside was... horrific, to say the least. Something like Stewart Little’s Chainsaw Massacre. I dropped the thing to the floor in shock and told them they could fire me on the spot but I was never touching that thing again, not even to pick it up from where I’d dropped it. Surprisingly, they didn’t insist, and went to disposable glue traps thereafter.

The funny story about that is when a live one dragged one of the glue traps into the middle of the floor one night as I was mopping up. I took him out back and pried him off the glue with a pencil... but he stuck to the parking lot asphalt after I got him loose. Poor guy. Eventually he got enough of a coating of dirt and loose grime & gravel to not stick to everything he touched, but I bet he probably didn’t make it anyway with all of that crap glued to him.
