Last year I left on a 2 week vacation to SC and one week into it my stepmother came home and decided we didn't need the downstairs freezer to be plugged in (I have no idea why that thought came to her) but she unplugged it and went to her girlfriends house for the rest of the week until me and my father returned. We walked in and it smelled a tad funky upstairs but we couldnt pin it, I opened the basement door and got smacked in the face by the smell of death
I would need to hold my breath, run downstairs, grab one bag of rats at a time and run upstairs throw them outside then breathe. I did that about 8 times then began the week long task of detoxifying the basement with a S**t-ton of Lysol and Fabreeze. That was by far the worst experience I've had, once in a blue moon I'll forget to put the rats back in the freezer but I usually remember before it's too late! But that whole incident was blamed on me by the fact "if you didn't have those damn rats in there this wouldn't have happened!"
