When Kat finally broke through into the next section of the cave, she froze for a few seconds as her brain tried to adjust. After smashing through rats for somewhere between an hour and two, for it all sort of blended together, the lack of rats was a shock that Kat wasn't immediately prepared to deal with.
Giving her wings a couple more flaps, Kat looked around at the shockingly barren tunnel. There were a few individual swarm rats scattered around the tunnel, but most weren't moving much, and a few were almost certainly corpses. The fact that the floor was completely visible at least until the cave turned was a decent shock.
No rats where harmed in the writing of this chapter.
P.S should I rename it? I actually did think we'd start fighting some rats before the chapter ended.
