They say they’ve genetically modified mice to make them unafraid of cats. I’m more concerned by the apparently-genetically-modified cat they’ve got in the vid-clip, who is even less effective at dealing with a mouse than Andromache.
(She can do the stalking, the patiently-lying-in-wait, and even the pouncing. After that, however, she isn’t at all sure what to do next, and when the mouse realises that the death blow isn’t really forthcoming, it’s able to scuttle away to safety. It’s very funny to watch. She’s better with wasps and spiders.)
