Right after Ai introduces the game to Keisuke and Z is thinking about his questions, the thought about the Catgirl questions kind of just trails off without any conclusion.
The scene changes based on C.H.E.A.T.S. (Awkwardness >= 4 or Horniness >= 4) to be a bit longer, but I've checked the code the scene is working as intended. The joke is that Keisuke spent time asking about that kind of stuff instead of something more important.
