When Juni seats on the window-sill with the window open (we live at the 6th floor) and she leans over the window too much, we say loud and insistently ptssssss, ptssss, until she changes her mind. And then, because the knows she did wrong, she comes to the person that ptssss her, chirping (she can't just accept it on our terms) and she kisses us, but, still chirping. And, when doing this, her wiskers shake and she is soo funny. But she still, goes there after kissing us. As Frostfrog said not so long ago, you can't command a cat.
BTW, very beautiful pictures with the suitcase. Esp, the first one.
