Blue Peter also taught viewers that cats and dogs could live together. The first feline to join the show was Jason, a Seal Point Siamese born on 3rd May 1964, who joined after appearing on an episode with his mother, brother and sister at just three weeks old. Jason lived until January 1976.
Possibly Jason's finest hour came in December 1975 when she played the part of the Cheshire Cat in the show's Christmas production, Alice in Blue Peter Land. With a voice remarkably similar to John Noakes', Jason snootily pointed out she was a Siamese cat before disappearing.
As with many of the other animals, Jason was looked after by Edith Menezes, a cat lover who travelled the world judging competitions. Edith worked on the programme for 27 years, before her death in 1994.
