I about fell out of my chair when I came across the article. It's so ridiculous, I thought it had to be a spoof but I don't think it is.

This article bemoans the fact that cats in the USA kill billions of animals/birds every year. Well yeah, that's what cats do and it's a vital role they play in the world's food chain.

Cats are one of the top threats to US wildlife, killing billions of animals each year, a study suggests...

The authors estimate they are responsible for the deaths of between 1.4 and 3.7 billion birds and 6.9-20.7 billion mammals annually...

The authors concluded that more animals are dying at the claws of cats in the United States than in road accidents, collisions with buildings or poisonings...

Birds native to the US, such as the American Robin, were most at risk, and mice, shrews, voles, squirrels and rabbits were the mammals most likely to be killed.

Now why is a British group even worried about cats in our country killing shrews, squirrels and robins? If not for cats we'd be over run with these other creatures.

Have we gotten to the point that this world can't handle death of any kind? Is it the goal of some that every living creature live on and on? Let me break it to them, things would not "work out" on planet earth if we started a campaign to save the robins, squirrels and shrews.

This final comment reminded me of my grandmother who didn't want her cat killing the birds and chipmunks:

Dr Marra said: "We hope that the large amount of wildlife mortality indicated by our research convinces some cat owners to keep their cats indoors and that it alerts policymakers, wildlife managers and scientists to the large magnitude of wildlife mortality caused by cat predation."

A spokeswoman for the UK's animal welfare charity the RSPCA said that a properly fitted collar and bell could reduce a cat's success when hunting by at least a third.
She did put a bell on Herman once for that very reason.
