In the wake of the earthquakes, I can understand why some people might decide to bring pets into work. That I can forgive, though I do wish I'd been consulted so that I could suggest telecommuting or other options.
The real problem is when they're left to run free through the office. I know there's at least one animal expert on this network - can anyone tell me how to properly kennel a small fluffy... thing? It's not like any animal I've ever seen, and I need to contain it until I can find the owner or call animal control.
