I'm not saying no, but when you start talking pets, you start talking policies. For office pets, there's what to do when somebody's allergic (which will happen day n where n is small). If it's really the "office's" cat, instead of, say, "your" cat, there's who changes the cat box, manages trips to the vet, keeps the cat over the weekend; the list is not endless but if you don't get down to "who cleans up cat piss in the server room" your list is too short.<p>Full disclosure: I am technical co-founder of a small lifestyle business, and my dog has been coming to the office with me since day 1, for 10 years. We allow anybody else's dogs to come in, also. Our rules are: Dogs only, on the "dog-side" of the office. Dog-side has a door that keeps dog-side dog-side. Dogs have to get along with each other. Dog messes are the responsibility of the dog owner. You can leave your dog unattended for a couple of hours if you get somebody to be responsible for walks & stuff.<p>A couple of folkways have arisen. No chicken bones in any dog-side garbage can is an example. If you get the dogs barking by kicking a tennis ball around, you have to calm them back down.
