I'm always on the look out for mouse friends when I'm walking to Euston because twice I saw them climbing a vertical wall, but tonight... No.

There are sadly many mouse poison traps here at my work. I do see the little cuties scurrying about though regardless. Although yeah, I have seen them dying in agony too. 
I at one point convinced them to use non-kill traps but I don't know how long that kept up.
I asked one person here to at least remove them from my office and they said to my face while there were traps in the room "there are no traps in your office".
