Niblet and Ralph may look a lot alike, but they are very different. Niblet loves noshing on crunchy potato chips. Ralph loves putting on headphones and jamming to his favorite records. But both cats have one thing in common- They love being friends and waving to each other from their windows across the courtyard of the apartment building they live in. One day, Niblet and Ralph decide it's time to meet in person (or in cat?). But when they mistakenly end up at each other's apartments, their owners think that Niblet is Ralph, and Ralph is Niblet! Will Niblet and Ralph be able to switch back to their proper homes, or will they be stuck listening to music (ugh) and eating chips (gross) forever? Better still, will they be able to bring their lovable (if not very observant) human families together?
