Jacky got a window sill yesterday. He was following step by step the whole process when my husband put it up. Last screw and it will be OK. Jacky was already up on it. Looking down to see, what’s still going on there I thought you were done already. Then finally, ready for him to watch birds and squirrels. Aww, he is so happy. The window is in the utility room and it’s situated higher up than the others. I just wish we had done this long ago so our other cats, before Jacky, had been able to enjoy the view too.
