(ZOO ANIMALS) PENNSYLVANIA — Orangutans can now stretch their limbs and explore more of the 42-acre Philadelphia Zoo outside of their enclosures. The Great Ape trail opened last week and plans to eventually be time-shared with big cats. The zoo already has a 700-foot-long Treetop Trail in use that allows small monkeys and lemurs to roam around zoo-goers overhead. The zoo has plans to open another trail to benefit zebras, hippos and giraffes.
