What is a badgers sett made of?

A badger's sett is made of a network of underground tunnels and chambers that the badgers excavate in the soil. The walls are typically reinforced with soil and may include bedding materials such as grass, leaves, and other vegetation for comfort. Badgers often create multiple entrances to their sett for easy access and to evade predators. The sett serves as a den for rearing young and provides shelter from harsh weather.
