Why are fur animals raised in cages?

Cage breeding and current size cages have been decided through research. The Ministry of Agriculture and Forestry determines the minimum cage size. Although wild animals move a lot, there is always a specific reason for their movement, such as finding food, a mating partner or escaping danger. These needs are met in farm cages. All fur animals live in a world of smell and the open sheds offer them the opportunity to observe the environment.
