In the video above, they are rescuing a fox cub who was probably looking for food and got his head stuck in a can. If you look through their videos, they rescue a significant amount of foxes both young and adults. This probably due to the large fox population in and around London. The fox you see above was lucky enough to released back into the wild almost right away. If he had been injured more, they would have taken him back to the wildlife centre for treatment.
