News that Mabel, the Blue Peter dog, has died has been received angrily by animal rights campaigners.
Mabel, a border collie, was a rescue dog and joined the BBC children's magazine show 14 years ago. She had the unusual condition, heterochromia - one eye was blue and the other was red.
"Once again another animal has died in the service of entertainment," said prominent animal rights campaigner Livia Culpable.
"Just how many helpless animals has that programme killed? It's outrageous.
"When I heard this news I checked their website to see how many creatures had suffered this fate. A list there goes back to Petra and Jason, the first dog and cat.
"There are 20 animals on that list! And it stops in 2005 - there's a note saying they're no longer updating it. How many more have they killed?
"It's an absolute disgrace and I am calling on all animal lovers to boycott this despicable programme!"
A spokesman who knows where the BBC is on his TV told us: "Surely they just die of old age? Isn't this a bit over-the-top."
But Ms Culpable added: "Biddy Baxter, Valerie Singleton, Chris Trace, John Noakes - we're coming for you!"
