Lumholtz tree kangaroo (Dendrolagus lumholtzi) Geoffrey was raised from baby to adulthood by Margit Cianelli and released into her 140-acre rainforest backyard 8 years ago. He since became the alpha male of the forest and came back to Margit's home regularly for his feed of almonds and spaghetti. In 2014, he stopped coming and is feared to have been killed by dogs.
