[Wildcat!]

I think they wanted this series to go without amy drama, and its more likely to happen with younger people. Fair enough, but I dont think its the reason for lack of young viewers. The previous series, with John mckririck, jackie etc, had more older housemates.
Its only natural anyways, becuase there is more young viewers, while school is out during the summer. The CBB always have more older viewers.
