Amazingly this room has rather little damage compared to the other rooms
enraged howls from something, whatever that something is you have no desire
to meet it.  The occasional rat scurries about but they give you a wide
berth, as if they fear you.  
A long suffering, rather abused looking lab rat is attacking anything that moves.

You pant and gasp, trying to catch your breath.
