Title: Mirror housing for birds as pets
Inventor: BRUNSCHWEIGER SEBASTIAN
IPC: A01K15/02
Filed: 1988-02-20
Abstract: Many people keep birds as pets in a cage and in most cases individually. Birds, however, are social animals and feel lonely when alone. They can even become ill from being alone - in particular budgerigars. With a housing made of specially assembled mirrors with bottom rungs and hooks for hanging in the cage, life can be made considerably easier for a lonely bird. If the bird is in the mirror housing, it can, according to position and movement, see itself more than once from different perspectives. As it does not know that it is seeing itself, it believes it is with a number of members of the same species which are playing and chattering with it. Moreover, among its supposed members of the same species, it feels safer from its natural enemies.
