This cat, in London, has an odd addiction to sitting in boxes, so his owner Bella tested out to see the smallest box he would sit in.

The clip filmed on September 11 shows the moment Jess the black and white cat squeezed himself into three boxes, each of them getting smaller and smaller.

"Jess has had a 'box addiction' ever since he was a kitten. He has a habit of pouncing into boxes from across the room. I've known him to attempt to sit in all manners of boxes, including trying to fit into boxes he has absolutely no chance with. So I tested out how small he would go!" Bella, the filmer, told Newsflare.
