On our way down to the local corner store for the Saturday morning paper my 5- and 1-year-old daughters and I meet a feline ritual. At the front gate of a home half-way down, every day without fail stands a generously fed black moggy with white socks and nose, long hair, and an inviting purr. She sits reliably waiting for … Read More

The nation missed an important opportunity at Raglan. If cats have been removed from the Raglan community then, had we the time beforehand to prepare, we could have tested whether cats were a beneficial urban predator, as claimed here and here. Cats on evidence. Evidence on cats… and their relationship with other … Read More

For cats to be a “beneficial urban predator” they must largely kill the exotic predators and competitors of native animals. Dr. John Flux believes his 17-year record of the prey one cat brought to him [1] proves that cats are good for native wildlife in cities. His belief featured prominently in the media to … Read More

Cats might be a “beneficial urban predator” according to Dr. John Flux and his conclusion featured prominently in the media to have a major influence on the public debate about cats and native wildlife.

Presence of native species, not evidence all is hunky-dory

Just because native species persist in our backyards despite being hunted by predators, like cats, it does not mean their populations are healthy. Our backyard can be a sink-hole for native species.

Our cats bring us only a fraction, less than half, of their prey and we are less likely to see the small, more palatable prey, like small reptiles and nestlings (Source: www.kittycat.co.za).

In the heat of public debate about cats and their impact on native wildlife, what scientific evidence did the media most use to inform?
