Breeding cell (noun): also called a breeding stall. A slave who is designated to be bred is taken there. Both kajira and kajirus are hooded and though they will never know the other's identity their coupling is public, observed by Masters and others.
When the girl is taken to the breeding cell or breeding stall, she is normally hooded. Her selected mate is also hooded. In this fashion personal attachments are precluded. She is not there to know in whose arms she lies, or piteously, and in misery, to fall in love, but to be impregnated.
