Don't blame cats for destroying wildlife – shaky logic is leading to moral panic


Voices my own thoughts about this claim. Cats have been around forever. They haven't suddenly transformed into the reason for the decrease in the numbers of birds, etc. People want to avoid the blame for what we are doing.

Conservationists and the media often claim that cats are a main contributor to a mass extinction, a catastrophic loss of species due to human activities, like habitat degradation and the killing of wildlife.

As an interdisciplinary team of scientists and ethicists studying animals in conservation, we examined this claim and found it wanting. It is true that like any other predator, cats can suppress the populations of their prey. Yet the extent of this effect is ecologically complex.

•••••

When humans denude regions of vegetation, small animals are particularly at risk from cats because they have no shelter in which to hide.

Small animals are similarly vulnerable when humans kill apex predators that normally would suppress cat densities and activity. For instance, in the U.S., cats are a favorite meal for urban coyotes, who moderate feline impact; and in Australia, dingoes hunt wild cats, which relieves pressure on native small animals.

Add in contrary evidence and the case against cats gets even shakier. For instance, in some ecological contexts, cats contribute to the conservation of endangered birds, by preying on rats and mice. There are also documented cases of coexistence between cats and native prey species.

Even when specific studies are good overall, projecting the combined “results” onto the world at large can cause unscientific overgeneralizations, particularly when ecological context is ignored. It is akin to pulling a quote out of context and then assuming you understand its meaning.
