Grömitz 1996, the liger-enclosure. By now housing three lions.
Back than, the ligers were an accident. The zoo rescued 1,1 babylions and 0,1 babytiger from a closing safaripark, where they should be killed. So they all stayed together. The lions breed several times, before the tigress got pregnant. Shortly after that the tigress moved out, so this would not happen again.
