Foxes (Vulpes vulpes)
The Fauna Centre at Caixa Catalunya's Les Planes de Son currently has three foxes, two females and one male:

Guilla is female, 6 years old and comes from El Vendrell. A couple found her near a housing development when she was a few hours old, they fed her and after a few weeks, when she was well, they brought her to the Fauna Centre.

Curro and Candela are two brothers aged 5 and come from Cadiz. They were found near a petrol station; a story similar to the previous one.
