Once upon a time, or perhaps not so long ago… beyond the mountains, beyond the forests, or perhaps somewhere nearby… in the well-known city of Krakow, dogs, cats, mice, and even humans live in great friendship. Until one day, thanks to the dog Thug and the cat Gryzelda, an unwritten law is broken, concerning who gets what if they fall from a stall onto the ground. And so a code is written, intended to apply to everyone. However, everyone soon interprets the code to their own advantage, until everyone ends up arguing with everyone else… a story about how breaking the law for personal gain always leads to chaos and deep divisions, and how the old saying "living together like cats and dogs" didn't just come from nowhere…
