Chins are misterious lil creatures... they always end up squeezed in a grange part of the cage. I used to see Boing all sueezed up under his Chin Spin, silly guy!
I laughed so hard, I almost spewed my coffee, LOL! Those pics are hilarious, but if I caught one of my chins in that position for the first time, I probably would have had a heart attack!
