I used to wonder when I went by some houses why the blinds were cracked open a few inches. Then I got cats! Even now a few are cracked open also for the dogs. If someone sees in, so be it.
My RB Sassy, when she was a kitten, used to climb up in the window and jump through the top of the blinds like she was supercat! I can't believe I got a second cat after her!
It looks like your two little ones had a good time.
