Still no sign of the varmint. Mouse. Critter. The cats aren't sniffing around or freaking out, I haven't found any droppings or chewed paper or food packaging. ?? Do mice ever die of natural causes? Maybe he was just visiting and didn't like the reception he got. It's not like the cats weren't excited to see him or anything, but ... maybe he wanted a greeting that was a little more low key.
Whatever. I'm keeping my eye out but I'm hoping he took a hike.
