Abstract
A cage construction for use in breeding fur-bearing animals such as mink, comprises a plurality of cages arranged on a stand, whereby each cage is provided with a breeding coop with an opening giving access to the cage. Each breeding coop is formed by a vertical plastic pipe open at both ends and having a substantially rectangular cross section, the pipe wall being formed by a central foam plastic layer and an outer and an inner solid surface layer. These layers are integrally connected.
