"Los Angeles and Mumbai, India, share many superlatives as pinnacles of cinema, fashion, and traffic congestion. But another similarity lurks in the shadows, most often seen at night walking silently on four paws.

These metropolises are the world’s only megacities of 10 million-plus where large felines — mountain lions in one, leopards in the other — thrive by breeding, hunting and maintaining territory within urban boundaries.

Long-term studies in both cities have examined how the big cats prowl through their urban jungles, and how people can best live alongside them — lessons that may be applicable to more places in coming decades.

“In the future, there’s going to be more cities like this, as urban areas further encroach on natural habitats,” said biologist Audra Huffmeyer, who studies mountain lions at the University of California, Los Angeles. “If we want to keep these large carnivores around on the planet, we have to learn to live with them.”"
