I laughed, because I so know that moment, when they suddenly go "on point" and you know they've finally seen the prey. I've also used cats as bug-disposal mechanisms. The only problem is that they don't always like to *eat* them, so I often end up with bug disposal duty anyway, only now it's been dismembered. Yech.

Actually, one time a cat chasing a moth really discovered mid-snatch that the screen was open, and bolted out the window. She didn't quite "fly," but it was rather a role reversal. (The moth, meanwhile, fled deeper into the house.)
