In Pictures: London Zoo animals celebrate Halloween with pumpkin treats

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.”
