Holly Willoughby stars in an Aardman-made Christmas animation encouraging cat owners to get their pets microchipped.
The This Morning presenter lends her voice to an animation made for the charity Cats Protection, which is based on the true story of a cat who was found three years after going missing from his home in Plymouth.
Ms Day said: “We were all heartbroken when Casper didn’t come back, particularly Daniel.
“The whole family is so excited that Casper’s story is being immortalised in this way – and hopefully it will encourage more cat owners to consider getting their pets microchipped.”
Willoughby, who provided the voice for mum Anna in the animation, said: “Casper and Daniel’s story is so lovely and, as a cat owner, it really struck a chord with me.
The three-minute animation is launched on Wednesday, with shorter version set to air on TV throughout December.
