Kits Rose
It's Catastrophe. Animal avatar actually works better though, I think...
This item could work, too:
Cheshire Kitten
And this item is cool, but it doesn't have an 'I Am' pose:
Astra: Cheshire Kitten
Though it might work if Kits could be shrouded or hidden somehow ... Seems like there used to be an item where the avi was hidden by a bush or shrub with green leaves in one of the poses?
