A Berlin zoo has creatively transformed leftover Christmas trees into animals’ snacks and toys, effectively reducing the waste of leftover products from the festival. /VCG Photo

The annual treats were offered to animals at Tierpark, one of the two zoos in Berlin, Germany on Friday. /VCG Photo

To meet different animals’ needs, the zoo put on well-prepared decorations on Christmas trees. Monkeys were offered trees with vegetables decorations and tigers got those with meat decorations, while elephants directly eat the trees. /VCG Photo

To ensure safety and quality, the zoo only adopted fresh and unused trees from selected vendors rather than accepting public Christmas trees as they might contain chemicals and other leftover decorations. /VCG Photo
