It's so, so, so obvious what's going on here. The bottom cat is looking at the hand on the right, and receiving direction. The hand is giving the finger sign for Latin Kings, which is sometimes used for the letters L.C. "Leap on the Curtains"! So he did. The skeleton is using its hand to obscure the speaker from the bottom cat, basically signaling to the cat NOT to "Listen to Your Masters Voice", who is yelling at him to get the F off the curtains. So the cat doesn't. The top cat is looking for how the sheer curtains are connected to the curtain rod, when the rod doesn't pass through them. And people think cats are stupid! Not me.
