Apocalypse miaow miaow

The end is nigh. Apocalypse has dawned. Everyone has gone, except for our heroes - Brownie, Apollo and their ragtag group of strays. Having raided a supermarket and defeated some very mean mutts, our heroes find themselves out of food. So when they hear a rumour of a Twonkies factory, and all the Twonkies they could ever eat, they think they've won the Twonkie jackpot. The only catch is the cat guarding the factory, and this 'cat' is MUCH bigger than any feline they've ever met. Can our heroes defeat their foe and claim the Twonkies for themselves? In graphic novel format.
