A rat that does not tell the whole truth? I am shocked, shocked, shocked.
Besides that, there is another way to deal with that:
Simply ask the humans or all-mother to deal with the prisoners, help them escape, they have the informations needed to safe the servants and after that the cat should be able to safe itself just fine
So, just trick the Ratking like he tried to trick you. At least that is my plan for my rogue party next time.
