Watch Ricky's report
Thirteen lions who were rescued from a zoo in Romania have arrived at their new home in Britain.
The animals were found stuck in cramped concrete enclosures and living in terrible conditions in the Eastern European country.
So the Yorkshire Wildlife Park started an appeal to raise £150,000 so they could bring the lions to the UK.
After three months of adjusting to our weather, the lions have been released into a nine-acre enclosure.
Yorkshire Wildlife Park's director, Cheryl Williams, said: "For the first time ever they'll be able to run as fast as they can. The youngsters haven't even thought of it yet."
