I forgot about this little fellow, sitting in my camera ever since Gus-Gus caught him in my office. I was able to get him away from her (her protest registered by a deep-in-the-throat growl) and into this oregano jar I'd been using as a guitar slide. The mouse seemed fine, scampering off into the night when I released him outside.
Look closely to see his little Spock-at-the-end-of-Star-Trek-II impression: one paw is pressed up against the glass.
