Here's what the posted article had to say.

> The RSPB says there is “no clear scientific evidence” that cats are causing bird populations to decline, but there is a perception among some British bird-lovers that cats are a menace and should be kept indoors. (In countries where cats are not a native species, such as Australia and New Zealand, they can have a devastating impact on wildlife.)

> “I do feel that cats are an easy target,” says Bradshaw. “Skyscrapers kill more birds than cats do. But you don’t see people standing outside the factories where glass is made, saying: ‘You’re bird-killers.’”
