Fleabag vs. Mutt is an artillery Flash game by Gametuner. You play as either a cat or dog (only dog in single player), both feuding and throwing stuff at each other during a windy day for reasons better left unknown. Players start off with four powerups that can be used in each round, but it's advised not to spend too long deciding or slacking off or you'll lose your turn.
r3gamerz here plays the game at its hardest difficulty and bone bonks the opposing cat into calling a truce in record time.
