Most people who live in the city have watched and fed the squirrels. Some cities have fox squirrels. You can identify this squirrel by the orange fur and large bushy tail.
Some cities have black squirrels which most people can identify, well most people.
I once was working on damage control in the city. This is removing animals that are causing damage to property. This lady swore a mink was living in her garage. A big black mink that climbed in the roof and made a nest inside the garage. This mink was tearing up insulation, chewing holes in the garage, and leaving his calling card on the hood of the car.
