A six pack of rats.
To battle the rodent menace I have 7 traps in my loft. Yesterday I went up to check them; 6 were full. Of the 6, 5 suffered a quick demise through a direct head strike. One unfortunate victim was caught by the tail and eventually passed away from probable starvation/dehydration after a struggle with its surroundings.
In an additional observation one of the head strike victims appeared to have had its hind leg eaten off.
