Abstract: In order to safely support a cuttle bone in a bird cage in a manner to prevent fragments of the bone breaking off and falling to the bottom of the cage or the bone becoming contaminated with bird defecation, a housing is formed of two halves or portions which telescopically engage with one another to form a variable size enclosure which has a window through which the cuttle bone can be pecked. Birds are prevented from sitting on the top of the container in a manner which allows defecation to fall on the cuttle bone by a slanted upper edge.
