I'm watching Hallie right now and she does this every morning and every night. She will bring one piece of kibble to the living room and play with it! She shakes her little butt and lunges at it, flips it in the air, growls at it and just shakes her little tail like she's doing the "kibble dance"
It is the funniest thing ever!
Oh and she never actually eats it. Simon hides around the corner and then runs really fast and scoops it up and eats it.
