A 15-year-old lioness has been given a clean bill of health after she was given a full "MOT" at the Yorkshire Wildlife Park.
Julie, one of the six lions at the park, was put under anaesthetic as keepers investigated tummy trouble the big cat had been having.
But staff said they used the hour-long window to conduct every test available on the much-loved animal.
Kim Wilkins, head of carnivores, said Julie had been presenting with stomach trouble and a lack of appetite so they decided to do a full check.
She said: "This is something we wanted to investigate further, to check there was nothing sinister going on, and it gave us the opportunity to do a full health check on her.”
Ms Wilkins said Julie was given an ultrasound to check on her gastrointestinal tracts, bloods test to check on her liver and kidney function and a check of her joints.
"It’s an opportunity to give her a full MOT, really," she said
She said the good news was that Julie appears to be in good health, despite her advancing years. Lions in captivity usually live to their early 20s.
Julie lives with her male friend Ares at the South Yorkshire park.
The lions have been in Doncaster since 2010, when 13 were brought over from a dilapidated zoo in Romania. Ares and Julie are still living in the seven-acre Lion Country along with Simba, Maria, Carla and Crystal.
