The names vary, the animal remains the same: whether you are talking about a mountain lion, a cougar, a puma or a panther, this could always mean you are talking about the largest wildcat living in the US. Their habitat is becoming smaller an smaller, so that tone of the threats to these animals is being run over by a truck:
“When California mountain lion “P22” crossed two eight-lane freeways and ended up in the urban wilderness of LA’s Griffith Park, he was lucky to make it across both alive.
Many mountain lions aren’t so fortunate, and are killed by fatal collisions with vehicles as they try to cross freeways that cut throught their mountain habitat.
The mountain lion known as P22 arrived in the urban oasis of Griffith Park about two years ago. And while most mountain lions have an average home range of about 250 square miles, P22 is barely surviving with just 8 square miles.
Right now, P22 is suffering from exposure to rat poisoning used in residential areas and mange. If he had a safe wildlife crossing, he wouldn’t be trapped facing such urban threats—he’d be back roaming his rugged habitat and open wilderness near the Santa Monica Mountains.”
