Continuity mistake: After Starbug and Blue Midget leave Red Dwarf, there is a shot of Blue Midget driving away from the ship, towards the camera. Cat and Kryten are the only two on board as Rimmer and Lister are on Starbug, but there are three people shown inside Blue Midget. This is because the shot was taken from series two, in which Rimmer, Lister and Cat were inside it. (00:03:25)
Continuity mistake: When Lister is telling Rimmer that he is going to die and that Rimmer doesn't need food, there is snow over his face, hair and coat collar, but a few seconds later, the snow has mostly disappeared. (00:09:35)
Answer: Presumably he does, but it's never been used in any material related to the show. He is the only Cat left (as shown in Series 1), so even if he had once had a name, nobody would know it.
