Keepers at London Zoo carved Halloween pumpkins for some of the 14,000 animals and stuffed them with special treats.

London Zoo’s zoological operations manager Dan Simmonds said: “With pumpkins in season, they are a sustainable snack for some of the animals, while others just love tearing them apart.”
