Years ago I got a kitten who had kennel cough, so she had to be "quarantined" because I had another cat. Since I lived in a small apartment at the time, this involved putting the kitten in my bedroom with her food, water and litter box. She took a dump one night that was so fragrant it woke me up. The thing was, though, it must have been a really deep sleep because I woke up thinking my roommate had just made one of his awesome pork roasts. I woke my boyfriend up mumbling, "Wake up, man...Brad just made us some dinner - smells great!" Once I became fully awake I realized that I was not smelling my roommate's tasty pork roast but my kitten's stinky shit instead. That and it was like 3 in the morning and there was no reason for anyone to be making a pork roast. So, yeah. I totally feel you on the whole cat-shit-while-sleeping thing. It sucks.
