I was happy to see Ace back home when I checked the box Wednesday morning.
But when he moved away, he revealed a little surprise. (Video is less than 15 seconds, with titles, but it's just good to see the little dude again. Clicking on images also gives a slightly larger view.)
In the late afternoon, Ace was gone, and so was part of the meal.
In the evening, the meal was gone completely, and Ace got his clean-plate-club ribbon. Ace did not come back today, but he is clearly in the area. He may just be protecting his turf nearby.
