Timeslides - S3-E5
Continuity mistake: When Lister is looking through Hitler's briefcase, he finds a banana and crisps sandwich with a bite taken from it. When Rimmer takes a bite out of the same sandwich later in the episode, the sandwich is whole. (00:08:30 - 00:26:15)
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.
