When our ginger was a very tiny kitten, she would go to sleep in my grandmother's pine chest of drawers, curled up with a possum tail. She loved playing with it, then would treat it like a warm mother cat to curl up next to.
Fast forward 3 years. We gave the possum tail to our latest addition, but he wasn't terribly interested. He's never been very kittenish in that regard. But this evening he humoured me, and he "Killed" the possum many times on my sewing table. After about 5 minutes he fell asleep, all tuckered out with the effort.
