'Aliens Did It': Cat Killings in London Blamed on Extraterrestrial Rippers

This is just one of the reasons being given for why more than 100 felines have been killed in south London since last October. 

In the course of its investigation the charity has received dozens of tip-offs — some from people who claim that it was aliens who are behind the killing spree. 

While others have tried to blame their exporters as well as neighbors for the killings, calling out anyone and everyone as the cat ripper. 

The false claims have caused RSPCA staff so much trouble that they are now claiming they are completely fed up. 

"This does waste our time. There are some reports that we can dismiss without looking at them but some are not that simple," RSPCA chief inspector Mike Butcher said in a recent interview.

"We have ruled out several bizarre alternatives from people collecting cat whiskers to aliens, it has got a bit out of hand with who they think it is."

"There are also people that say [the killer] likes skulls of cats and cat's tails to put on the wall."

"There are people dropping a neighbor in it who they don't like or trying to get back at an ex and when we follow it up, it turns out it was just a domestic situation.

More than 100 cats have been found decapitated and disembowelled near their owners' homes in Croydon and nearby West Norwood since last year.

Animal rights group PETA is offering US$7,200 for information leading to the arrest and conviction of the "twisted individual" known as the "Cat Ripper of Croydon."
