Penning wild animals in tight unnatural quarters seems to have always been a hallmark of us humans................In AD 100, .Native Americans occupying Teotihuacán,(the ancient city some 50 kilometers north of today's Mexico City) apparently kept Wolves and Pumas(perhaps Jaguars as well) penned up in cells................The purpose of this was to use these animals in religous sacrificial ceremonies.........

New archaeological findings have shown that carnivorous animals were kept in captivity in the Americas as far back as the first century AD, 1,000 years earlier than any previous evidence had shown.Studies of the animal remains — including pumas, eagles and wolves — found during excavations at the ancient city of Teotihuacán between 1998 and 2004 have shown signs of brutal treatment by their captors.

There were also indications that some animals had been fed the meat of humans.

The remains of almost 200 animals were found underneath the Moon and Sun pyramids, predating the zoos described by Spanish conquerors and missionaries.

The positions of the animals and nearby drawings showing them eating human hearts suggested they were used in sacrificial ceremonies. Now, isotope analysis, which studies the atoms in organic remains, has offered further information about what those animals might have been eating.

High levels of some nitrogen isotopes indicated that they might have been fed humans or dogs, while a carbon isotope provided evidence of having eaten maize, further implying they were kept in captivity.

There were also signs of injury, such as fractures and lesions possibly caused by having been tied up. Three eagle skeletons showed stress on the lower legs, indicated they had been tied to a perch.

Other signs showed evidence of infection which would suggest they were kept in close quarters.

Teotihuacán, famous for its Mesoamerican pyramids, is believed to have been established around 100 BC and lasted until the seventh or eighth century. It was located about 50 kilometers northeast of where Mexico City is today.
