The automatic laboratory lights clicked on, flooding the complex with artificial daylight. With a start, Nova blinked the sleep out of her eyes. She slowly looked around the small lab room. Dorian was still asleep in his bed box, which was next to hers. Nova made a little rabbit-type yawn, licked her front paws, and washed her face. She stretched and hopped out of her bed box. Nova looked like a small black ball of fur with tiny black ears. She and Dorian were Black Dwarf rabbits that had been carefully raised and studied under controlled laboratory conditions for eleven successive generations. Her name was at the bottom of a large chart as NOVA 11/N. This meant she was an eleventh-order rabbit with 2,046 carefully raised and charted ancestors. Dorian was also an eleventh-order rabbit but from another complete line of Black Dwarfs.
