"Evidence of rat poison is found in a sickly puma whose territory includes Griffith Park. Researchers suspect a link between poisons and mange."
"The mountain lion known as P-22 looked majestic just a few months ago, in a trail-camera photo shot against the backdrop of the Hollywood sign.
But when a remote camera in Griffith Park captured an image of the puma more recently, it showed a thinner and mangy animal. Scientists sedated him and drew blood samples. They found evidence of exposure to rat poisons.
Now, researchers say they suspect a link between the poisons and the mange, a parasitic skin disease that causes crusting and skin lesions and has contributed to the deaths of scores of bobcats and coyotes. A National Park Service biologist applied a topical treatment for mange and injected Vitamin K to offset the effects of poisoning."
