I'm not sure if it's common puggle trait or not, but Oates has a special talent... for catching flies. Bare mouthed! No chopsticks necessary. I've seen him do it 3 times now; his agility is superb, taking mere moments to catch his prey in mid-air.
He must like the way it feels in his mouth too because he doesn't just swallow it, he's got to play with it for awhile. Spitting it out - looking at it - tossing it back around in his mouth, and finally, he'll eat it. Maybe he learned his skills during he street days. However he learned it, it beats having to chase them around with a fly swatter, and no carcass clean up!
