An orphaned mountain lion cub who was rescued by hikers is living a life of luxury at a zoo - with her own special back scratcher. Five-month-old Rose was found 21lbs underweight and wandering around a park in San Mateo, California by walkers, who reported her to wildlife authorities. After a painstaking five-day hunt, wildlife biologists and game wardens tracked her down and took her to Oakland Zoo for medical treatment. Now she has gained over 4lb and gets regular back scratches from her doting keepers to help her make a full recovery. Dr. Alex Herman, VP of veterinary services at Oakland Zoo, said: "We can already tell she has a feisty spirit and an obvious will to live, and we’re thankful for that.” California Department of Fish and Wildlife (CDFW) biologist Garrett Allen said: “We appreciate the hiker and the team at Midpeninsula Regional Open Space District who alerted us to the mountain lion cub and its condition. "The Santa Cruz Mountains provide good habitat for mountain lions, but it’s rare to see a mountain lion because they’re elusive creatures. "If you see a mountain lion, do not approach it. Adult animals, when out hunting prey, may leave offspring somewhere safe for up to days at a time. "Seeing a young animal by itself does not indicate that it is an orphan and intervention is appropriate.” On April 5, a group of hikers saw a severely emaciated lion cub roaming the Thornewood Open Space Preserve alone, and reported the sighting to the Midpeninsula Regional Open Space District. District game wardens and biologists from the CDFW setup cameras and patrolled the area daily to find her. Four days later, the cub was spotted again on a camera but, by the time the wildlife biologists from both agencies arrived and searched, she had disappeared. Finally, at about 3pm the following day, Rose was located and taken to Oakland Zoo by two biologists, Garrett Allen and Megan Senour, where a team of veterinarians were standing by to assess and treat her. She was dehydrated and starving, weighing only around 8.8lbs, when a typical female mountain lion cub of her age should have been around 30lbs. The poor cub was also covered in fleas and ticks, and initial blood tests revealed she had a low red blood cell count.
