What does it mean to put a fluffy blanket in the rabbit's new cage?

A fluffy blanket is put in the rabbit's new cage, which means living habits. It is a living habit for rabbits to pick up things. They bite whatever they see. For tens of thousands of years, rabbits have been foraging and digging holes in the wild, which requires the continuous growth of teeth and nails. Now domestic rabbits have no place to dig holes and can only bite people.
