An animal rights group says Spain's Queen Sofia is asking Barcelona City Hall to move Susi, who's 36, to a larger space, perhaps at a safari-style park.
The Foundation for the Adoption, Sponsorship and Defense of Animals said Wednesday that it wrote to the Royal Palace in February, and the queen promised to intervene.
Born in the wild in Africa, Susi has been sad since her female companion, Alicia, who shared her pen, died in 2008, the organization said. It said is has not yet received a response from city hall, which runs the zoo.
