Cat transit through FRA from India: Titre test enforced?

I’m flying Hyderabad → Frankfurt → Chicago on Lufthansa on June 16th with my two cats.

The cats would ideally travel in cabin (one of them is currently registered as excess baggage) and the FRA layover is 1hr 45min.

I’m trying to understand a few things from people who have ACTUALLY done this route recently:

1. If the cats are staying airside in Frankfurt on a single Lufthansa itinerary, are they normally checking/enforcing EU rabies titre requirements for transit cats from India?

2. Has anyone here transited FRA recently with Indian cats going to the US without a titre test?

3. Is in-cabin generally “safer” than excess baggage in terms of transit scrutiny/document checks at FRA?

4. I’ve heard Frankfurt refuses pets in excess baggagel transit unless the layover is 4+ hours. Is that true?

5. Has anyone used gabapentin for Lufthansa cabin cats recently? I know airlines dislike heavy sedation, but I’m talking about mild vet-prescribed calming doses for anxious cats during a 20hr journey.

I’m not trying to break rules or do anything shady. I’m just getting extremely inconsistent information and trying to avoid my cats getting stranded in transit because one employee interprets things differently from another.

Would really appreciate firsthand experiences especially in the past 2 years.
