Presenting the new Sainsbury’s Christmas Ad. Mog the cat sets off a chain of unfortunate events which almost ruin Christmas for the Thomas family. Can she pull it all back to save the day? See for yourself!

Sainsbury partnered with HarperCollins Children's Books and world renowned author and illustrator Judith Kerr to create a Christmas story based on her much loved character Mog. They hope that families will come together this Christmas to enjoy this very special story.

If you enjoyed the story, you can buy the beautifully illustrated book. Every penny of the profit from sales of the book will be donated to Save the Children to be used towards improving child literacy.
