The Toronto Zoo officially said goodbye to Trilly the 11-year-old moose. A beloved resident, Trilly was euthanized following several months of decline. This loss comes on the heels of the recent deaths of two other zoo animals—a red panda cub and Matumaini (Matu), a 2-year-old Masai giraffe—for unrelated reasons.

The red panda cub died at six weeks of age due to health complications—chiefly, his lack of fat reserve. In a social media post, zoo officials explain, “Red pandas have low rates of offspring survival both in the wild and in human care and recent scientific studies have shown that as few as 40 per cent of cubs reach their first birthday.” Meanwhile, Matu passed away from complications related to anesthesia during surgery.

Regarding Trilly’s case, zoo officials highlighted she exceeded the typical life expectancy for moose in human care, stating “After performing the gross postmortem on Wednesday, we suspect her very thin condition was due to malabsorption, but further test results will provide a final diagnosis. Moose are notoriously hard to feed in old age, and we are thankful ours have done much better than most moose in managed care settings.”
