I just saw someone on twitter say that if outdoor cats were a problem we’d hear about it more.

Outdoor cats are a problem.
There, you just heard it from me, your friendly neighborhood corvid lover, trained ornithologist, and cat owning twitter scientist.
We just watched the neighbor's cat catch a bird. Please keep your cats inside.

"Help protect native wildlife. Every year free-ranging domestic and feral cats injure and kill millions of wild animals, especially song birds. Please consider keeping cats indoors. Cats kept indoors live longer, they are less likely to contract disease and parasites, they are protected from traffic, and they are protected from urban coyotes that will catch, kill, and eat cats.

"Each year at least 60% of the wildlife we admit to our Centre have been caught by cats."
"Cats account for almost three quarters of non-natural bird deaths."

Many people believe outdoor cats are no big deal because they just fill the ecological role of missing wild predators. Actually, new evidence suggests house cats are killing at up to 10x greater rates than those natural predators.https://t.co/juptB031tD pic.twitter.com/nQvMor8UrJ

"But I've never noticed my pet #cat kill any #birds"

Of cats that kill #wildlife, only 21% are presented to owners. 30% eaten. 49% are LEFT TO ROT (https://t.co/prqGGsRBTi).
Well-fed pet #Cats kill for pleasure, often tormenting their victims
So, is there overwhelming, PEER-REVIEWED scientific evidence that free-roaming cats are a threat to global #biodiversity?

YES
