The Advent Calendar Challenge Welcome to our online Advent Calendar We have had the most amazing response from animal lovers, who have risen to the challenge of sharing their pet's photographs. Each day, a new challenge has been posted and we have really enjoyed sharing them. Below is a collection of some of the amazing photographs we have been sent. We still have a few days left of our Advent Challenge, so it isn't too late to join in the challenges. Booking for this event has now closed.
