In the Foreign Office, Palmerston the cat was brought in as the official mouser. Reports suggested when Palmerston first arrived, he captured and killed over 27 rodents although that may be an under estimate since these are only kills witnessed by the Foreign Office staff.
Now the Foreign Office staff is being told not to feed Palmerston. Apparently when he gets too much food from the staff, he gets lazy and stops chasing mice. Therefore Palmerston needs to get back to doing his job and stop taking handouts, which goes to show that even cats can be easily corrupted with the right kind of bribes.
