Linton Zoo lions 'recycle' Christmas tree treats Big cats in Cambridgeshire have gone wild for Christmas tree recycling after a zoo appealed for people to donate their discarded festive fauna. The trees are being reused by Linton Zoological Gardens as toys for the lions, tigers and snow leopard. Manager Dawny Greenwood said the scented trees are "almost like catnip" for African lions Zuri (male) and Safina. Video courtesy of Linton Zoo
