Muffin used to pout. She'd lay down somewhere in front of me or nearby, turn her rear end toward me, and put her head down on the floor. No matter what I'd say, she wouldn't budge. The minute she'd hear me get up, she'd raise her head up and look back to see if I was coming over to her!
Kacee is still being spoiled, so other than crying, she hasn't tried any other tactics!
