It's been all over facebook and at last on the news and local papers. In the South East England, near Croydon, Bromley, Orpington etc, there is one nasty "£$%^ who is kidnapping cats and doing very gruesome stuff to them. The said person is taking trophy parts to keep as a treasure of his deeds.
The Police have at last decided to investigate after numerous cats or parts of cats have been found:

The person, I think, is showing classical psychopathic tendencies and may well progress onto people, so needs to be caught ASAP.
