Their moving and they are taking the cat.

Just when I finely get a photo of the cat on the roof, I notice a lot of movement in the apartment across the street. They were moving out. I watched the cat, watch them. That’s probably why I was able to take photos of the cat walking on the roof. The cat was too interested in what they were doing in the apartment.
With the cat gone, what on earth will I watch out the window?
