Unless this is an elaborate feint to get around the shield, land, and twist aside to strike or swipe at the mouse from behind, my money's on the mouse - deflect spearpoint, follow momentum to stab the cat once as it lands, then get the hell out of dodge and into an inaccessible hole while the cat bleeds out.
But then again, if the cat adapts and follows up the pounce with a sweep with the shaft, the mouse might not be able to recover to gain enough leverage to stab...
My goodness. That is awesome. I love it. Everything about it.
If this drawing was a person, I would marry it. Alas, paper doesn't make good conversation or meals.
The mouse's pride and the Cat's hat is something I particularly adore. The mouse seems over confident and the cat may be German. (German's had hat's like that during the second war, didn't they? Or was it the first? My history is rusty. It may have been the Russains. ANYWAY, it was some country's hat for sure.)
