Adam and Janey (Eugenia) live in London with four pet cats. They spend their spare time in Galicia, Spain where they care for a colony of feral cats, along with their neighbours who cook for them (the cats that is!) macaroni with meat sauce.
Adam is an archaeologist from Canada and Janey is a public health consultant who grew up in Australia.
The cats in the village in Lugo are feral which means they have not been socialised to be near humans. There are about 20-30 individuals as at September 2015.
