Has Sainsbury's just pinched John Lewis's Christmas advert crown? Hot on the heels of the latter’s tear-jerking 'The Man On The Moon' advert, Sainsbury's has released a heartwarming new festive ad which sees children's author Judith Kerr - who penned The Tiger Who Came To Tea - resurrect one of her other much-loved characters Mog The Forgetful Cat. 

With his flattened ears, thick grey tabby coat and signature anxious expression, Mog appears in the ad in CGI form in a 3-minute film titled 'Mog's Christmas Calamity’, which sees the cat spark a chain reaction of accidents which very nearly burn down his owners' house. 

John Lewis's 'The Man On The Moon' was released last week and sparked the usual wave of 'why am I crying at an advert?' outbursts on social media. But has Mog just blown it out of the water? 

Sainsbury's are pushing pretty much all of our buttons at once with this one. There's the crafty dose of nostalgia that comes from bringing back a children’s book character a huge number of adults grew up with - and a Judith Kerr one at that - while the character in question just happens to be the most social media-friendly animal there is: a cat. 

Sainsbury's have also borrowed John Lewis’s anti-materialistic ‘it’s the little things that matter’ theme, as all the neighbours muck in to help the Thomas family by cleaning up the house and inviting them to share Christmas with them. 

And despite nearly causing a catastrophic and potentially life-threatening house fire, Mog isn’t banished outside into the snow but gets to join the Christmas celebrations with a plate of his favourite food (eggs).     

The advert ties in with the sale of a special Mog’s Christmas Calamity book and stuffed toy, with proceeds going to Save The Children. A cat, a heartwarming festive message and a charity campaign? Yep, Sainsburys have pretty much nailed it.
