<human>: So a close friend of the family is leaving to another state for the unforseeable future, so I offered her my place, shes staying at mine and her cat in my room. The little kitty had been running around pouncing, sniffing and quizzically looking at all my crap for hours.

Fast forward to 2am. 

I wake up because the movie I had on had a louder than usual scene with awful Hayden Christensen acting so I flung up, looked around and see little kitty sleeping on my bed. I pat him, he noticingly raises his tail and boom.

Butt worms. Butt worms on my sheets, butt worms on a shirt he was half-on, butt worms on his butthole, it was like a bowl of wriggly rice bubbles. I've instantly made the guest wipe that parasite infested felines ass and put him back in his little parasite cage where he can resume his parasite infested sleep, then gone and had one of the most scalding showers of my life.

Lesson: don't be lenient with unknown cats ever again
