Rotten Ralph was aired from 1999-2001 on CBBC.

It was a stop motion tv series based on the books by Jack Gantos about a mischievious cat named Ralph who lived with his owner Sarah and her parents.

Ralph was always playing mean practical jokes on his family and getting into trouble hence his name "Rotten Ralph".

He was always punished mostly by Dad who often seemed be on the end of Ralph's jokes.

They often had visits from Ralph's cousin, Percy who always annoyed the naughty cat by his good manners and skills on the xylophone. Ralph always tried many attempts to get rid of him. However Ralph still loves his family and they love him.

A Rotten Ralph CD Rom was released by BBC Multimedia called "Rotten Ralph - Big Night In" on 13 Oct. 2000
