So it turns out Shop Cat was pregnant but not yet showing when she wandered in. Over the past couple of weeks it became very obvious and one of the office types was supposed to get her to a family member that works in a vet's office. That didn't happen in time so Monday morning we came in to find kittens! Looks like she had 4 but 2 didn't make it.
