I love cats, they're great; intelligent, affectionate, lovable, and this one was particularly nice, so picking it up and giving it a few slaps and a bit of a rough time was galling, even though it was unfortunately necessary. See, if you're hiding in someone's spare bedroom waiting for them to turn in for the night, the last thing you need is a cat meowing at the door trying to get in to see you because you've been stroking it all day. A bit of a shake and a growl in the cat's face and that's all that's usually needed for it to give the spare room and the horrible bastard inside a wide berth for the rest of the night.
