When the Cat fell ill with a libido-related illness, the boys from the Dwarf had to find a female felis sapien for Cat to mate with, in order to cure him. Fortunately, the navicomp of Starbug located such a rare and unique life-form on a GELF transport spacecraft. Unfortunately, it was headed into GELF space. With no choice, they followed it, leading them to the Brefewino trading world.
It was very Earth-like, sunny and heavily forested. The Brefewino trading town was heavily guarded and fortified, but the Dwarfers were allowed entry by pretending to be merchants. Inside the town were bustling and raucous watunga that acted as shops, gambling dens and drinking-holes. In the center was a marketplace for slave auction, where felis sapiens were the favoured commodity.
Cat located the female of his species, Ora, who was being held for slave auction, but an attempted jailbreak failed. Lister came up with a plan to use Kryten to cheat at four-dimensional pontoon, thereby winning enough mushy peas (the currency of the Brefewino homeworld) to buy Ora themselves. However, this plan failed due to the leader of the Brefewino, Zural, being more savvy than the Dwarfers. Cat later killed Zural after Zural bought Ora, revealing him to be a traitorous felis sapien in disguise. The Dwarfers left the planet with Ora, but Cat left her on another unidentified S3 Planet after mating. ("Identity Within", Series VII)
- The Brefewino planet was a galactic trading center for droids and different races of GELFs. The Simulant Trader was likely referring to this planet when he told Able to get Kryten fixed and "ready for market" in the episode "Beyond a Joke", which took place a few weeks after the supposed events of the unproduced episode "Identity Within". The location of this "market" remains unknown, but the Brefewino planet is the only location which fits. The Kinitawowi tribesman seen aboard the Simulant's ship reinforces this, and may have been from here, or been the Simulant's GELF liaison.
