Animal Airport.

Heathrow Airport in London, one of the world's busiest, isn't full of just people from all around the world who pass through its doors. This series tells tales of the many creatures that end up at the airport's Animal Reception Centre - some legally, many illegally - and the staff who handle arriving and departing shipments of animals in every shape, size, breed and colour. Along with thousands of cats and dogs, the centre has welcomed sloths, giant octopi, bears, elephants, tigers, lions, sharks, alpacas, venomous snakes, vampire bats, and Britain's equestrian team.
