I'm just getting to Big Ben and I find milk bottles on some of the floors. I walk to one and spill it and this cat starts talking and threatening not to do it again. Of course, i do it again a couple floors up and he says I'm in for it . Then, I find the same cat a couple floors up and he fights me with 2 minions. I have only done this instance once, my question is, what is the point of the milk bottles?
