Sainsbury's Christmas advert features Mog the Cat

Forget Grumpy Cat, Nala, Maru and or all the other famous felines of the internet.

Sainsbury's has just revealed the much-loved children's book character Mog as the star of its Christmas campaign and people can't get enough of her.

The ad – stretching to an epic three minutes and 30 seconds – features the calamity-prone cat in a brand new Christmas tale written by the author of the original series Judith Kerr, who even makes a cameo appearance.

Kerr, who has sold more than nine million copies of her Mog books and The Tiger Who Came To Tea, sends the beleaguered cat into the midst of chaos when the oven catches fire in the middle of the night.

But in a twist that will be familiar to readers of the original stories, Mog inadvertently calls the fire service and saves the house in time for the neighbourhood to come together to help the family clean up and enjoy Christmas dinner.

For some, the advert is bringing back back those childhood memories.

For this person it was pretty much a blast from the past.

The new book – Mog's Christmas Calamity – is on sale exclusively in Sainsbury's stores for £3 alongside a £10 soft toy.

The supermarket, Kerr and publisher HarperCollins are donating all profits to the Save the Children-led Read On. Get On campaign that aims to help every child become a confident reader by the age of 11.

It seems the love for Mog the Cat is running high at the moment – someone has created a Twitter account for the fictional cat.

It has gathered 133 followers so far.
