Junior's Mother was a female cat that Francis bred with in Cave Canem. She was never named.
She looked very similar to Francis, colored whites and blacks with eyes shaped like diamonds. Compared to Francis, however, she was notably younger.
Junior's mother was a stray cat who encountered Francis while in heat. She fancied him enough to allow him to mate with her and bore three kittens from their mating some months later. However, most of them -- herself included -- did not last. One kitten died from exposure, the other from an accident with a truck, and her final kitten Junior when to seek out his father.
She herself passed away after being infected with a deadly virus.
