Why are there foxes in the streets of London?

The presence of foxes in the city center of London could be explained by the abundance of food (garbage cans, rats, mice, etc.) and of shelters (many green spaces and parks) - but also by the absence of predators.

Foxes are not known to be aggressive: they attack only out of fear and - although they have become accustomed to the human presence over time - tend to move away from humans and larger animals.
