There is nothing better than content kitties and yours definitely are, Debbie!!! We have strange windows in this house. It's a 70's house with huge windows that open side to side. The good thing is that the ledges on them are enormous and the cats will perch on them to look outside. Of course, mine go outdoors anyway, so they don't hold quite the fascination that yours do. I had a cat, once, named Shrimp Boat, who hated the outside, but loved lying in the window surveying everything. She was so fat that I often worried about her leaning so hard on the screen that she might bust it out and take a tumble! Never happened, thank goodness, but the screen in the kitchen window did come loose at the bottom and out she went, once! Never saw her try to lie in that window again!
