Nasty Story for the Day

Alright, so, I work in a railroad musuem. The building is not particularly well sealed since there are tracks running in and out of it, etc. Occasionally we get rats or mice in the museum. Today, a visitor pointed out to me a smallish rat (about 4 inches long, not including the tail) stuck inside one of the exhibits-- a surveyor's tent to be precise. The rat was stuck on a sticky trap and trying to pull itself off. Ok, already, that's pretty gross. But wait! There's more! Upon further inspection it seems there are two rats stuck there-- one is dead and the other is stuck and struggling to free itself. When I was telling my coworker Becky about this she said, "Yeah, that is gross-- it's trying to rip it's leg off so it can get away." Sick.
