Our cat is 16 years old, somewhat arthritic, and sleeps most of the day--but she was back to her roots protecting us last night, stalking and running--apparently a mouse is in the house. We live in a wooded area, and this time of year they sneak in when they can. The cheese was removed from the trap, but it didn't spring. We're not sure who ate it--the cat or the mouse. Sort of like watching politics, isn't it?
