Linton Zoo near Cambridge has found an unusual way to recycle old Christmas trees as people take down their decorations on the twelfth night.
The zoo is asking for people's old trees, to give to their lions. The animals love to play with the trees and rip them to bits.
The wood from the trees is also used to heat the animal enclosures.
It's the third year the xoo has taken in old Christmas trees and this year they have had double the usual amount.
The trees are used as part of the "enrichment" of the animals, trying to enhance their natural way of life.
