Niblet and Ralph may look a lot alike, but they are very different. Niblet loves noshing on crunchy corn chips. Ralph loves jamming to his favorite records. But both cats have one thing in common: they love being friends. But when Niblet and Ralph accidentally get trapped in each other's apartments, their owners think that Niblet is Ralph and Ralph is Niblet! Will the feline friends get back to their proper homes, or will Niblet get stuck listening to music (ugh) and Ralph have to eat chips forever (gross)? Better still, will they be able to bring their loving human families together?
