While my cats frequently visit my home office, and usually take up residence on top of the filing cabinet when I'm in there, I'd never take them into my actual work office. I work in a 90% female environment and it seems that all the women go absolutely wappy and turn into some sort of weird creatures the minute a small human, or something small and furry appears. They all start cooing and going "Awwwwww! Innitsweetandcuteandadorable!" The cats would love it because they'd have more fuss than they could ever wish for, but the office would simply grind to a halt and no work would ever get done.
