The red fox is such a fixture of life in London that it has its own ambulance service. The critters that have admirers and adversaries are well adapted to city life but living on the streets, alleys and back gardens of a dense urban environment can be rough. When they are ill, injured or abandoned as cubs in south London and its leafy suburbs, The Fox Project is often there to help. The organization that began as an information service to educate city dwellers on coexisting with the animals rescues 1,400 foxes a year, including about 400 little ones.
