How do you explain the musical CATS without sounding odd?

Lol I was just in this show! Well say there was this one cat who left the tribe of cats and no one likes her. So one day she shows up during their yearly gathering. Every cat wants to got o the heaveyside layer but only one cat can be chosen to recive their extra lives from heaven because all the main characters are all on their last lives and cats have 9 lives. So each cat is presented through a song ( Example: Skimbleshanks :The railway cat is a song all about Skimbleshanks. Jellicle songs fpr Jellicle cats is about how great they all are because they Jellicle cats!) It's almost like american idol for cats! So anyways Grizabella the glamour cat ( who no one likes cause she left them one day to go see the world. She found out how bad it really was so she is trying to come back to her old life) So she sings Memory and then she is accepeted. But in order to do soshe has to go to the heavyside layer.( Cat heaven) And in the end she goes to the heavyside layer! Yes i do agree this musical is really good!
