Two things:
1) fly paper is disturbingly effective. While the adult side of me is pleased that it’s helping get my fly problem under control, the side of me that likes frosting is horrified at my willingness to unleash a glue-based genocide upon my foe. Seriously, can you think of any worse way to die than rupturing your organs trying to pull yourself free from glue?
2) when your cat manages to knock an unspooled roll of flypaper — fully laden with fly carcuses (carcii?), mind you — off its hook, allowing it to become fully entwined into the cat’s fur, it is equal parts hilarious and heartwrenching. The more she tried to get it off, the more stuck she got. Scissors were eventually required. Despite having dead flies glued here and there she seems to be taking her impromptu trim rather well.
