Originally, when I posted these pictures I was convinced that Dante was playing with a dead mouse. I wasn't about to take a close look, so I asked my husband to dispose of it (we didn't want it rotting on the lawn).
However, it turns out it wasn't a mouse at all, but a rock which was indeed mouse-shaped! That Dante sure is a funny boy. He was acting exactly as I've seen other kitties act after a kill.
Supermancat that Dante is, I guess just about anything (including a rock) will fire up those hunter instincts!
