Families of foxes often have more than one den in their area, but usually only use one for breeding. A breeding den is much larger than a hole used for sleeping and can go down as far as 3m below the ground.
The mating season runs from late December until February and vixens usually start digging a den in February in which to have their cubs. Gestation is a little under two months and most cubs are born in the middle of March.
The babies stay underground for about five weeks but, with a bit of luck, I could see little fox cubs on my lawn in just over a month's time.
