Visible crew/equipment: When Lister does the log at The Beginning of the episode, a boom mic shadow can be seen on his face throughout the scene. (00:00:40)
Visible crew/equipment: When Lister sneaks in to switch Kryten's head, as the camera follows Lister and goes around past the wall, the shadow of the camera can be seen in the green light. (00:09:20)
Visible crew/equipment: When Rimmer says that Kennedy was a fine man, a boom mic can be seen at the top of the screen. (00:20:22 - 00:21:17)
Suggested correction: Lister can only see M-Corp products and M-Corp employees. Cat is not an employee of JMC or M-Corp, so he disappears. Lister is the only member of the crew who is employed by M-Corp at this point.
Suggested correction: Cat was a descendant of the cat Lister brought aboard Red Dwarf. Would it be possible that the new owners might have stricter security controls, and Lister was sent to Stasis for a different reason?

Inventing Deux ex machina explanations for a plot hole doesn't make it any less of a plot hole. M-Corp erases all of the Jupiter Mining Corporation's equipment, personnel and infrastructure from Lister's life. In no way is Cat a part of that. He has no connection at all to the Jupiter Mining Corporation, and until he meets him in Episode 1 no connection to Lister, either.
If M-Corp only erased JMC equipment from Lister's life, then Kryten, who belongs to DivaDroid and not the JMC, wouldn't have disappeared either. He disappears as he doesn't belong to M-Corp, not because he belongs to the JMC. Cat has no connection to M-Corp, as he wasn't a part of the JMC (as you pointed out), and is therefore erased for Lister.
