I guess it's officially getting cold. Spouse has the day off of work, and has escorted yet another uninvited guest a few miles away. (Again, the small trap was "tripped" but the large trap did the job.) Gotta figure out where Gandalf-mouse scratched his rune and find a way to discourage this.
This one had large eyes, was tawny-brown in color, and didn't want to leave. Other than the color, it sounds disturbingly like the "otter-like" one I released a short while ago.
