Leopard kill in a tree 

I saw with interest your picture of a leopard's kill hanging from a tree limb in the Serengeti.  Do you by any chance know how the leopard gets the prey to hang like that?  It seems draping the kill over a tree limb would seem the easiest (and preferred) way, but hanging it by the heels without having fingers or opposable thumbs is pretty impressive.  Just asking.  Thanks.
