Part 1 of 2. The Season 34 premiere focuses on the work of human caretakers of orphaned baby animals. At Australia's Cape Otway Conservation Centre, the staff cares for a baby koala found along a road. It's weak and underweight, and should be spending its first six months inside its mother's pouch; the staff gives it a teddy bear to hold for comfort. At a sanctuary in Costa Rica, meanwhile, primatologist Sam Trull cares for six baby orphan sloths, including one that has pneumonia.
