I think he will find if he investigates that his figures are off. Also, some of those small mammals are mice and rats. I know that some of the bird rehabbers have it in for the tnr people, but it is the tnr people who are working to reduce the feral cat population and reduce rabies exposure. Same is true for the illegal shooters, but I have other problems with that. TNR helps to reduce rabies in the wild population. The other two methods that are proven are using bait with vaccine, and using wildlife rehabbers to vaccinate raccoons.
Of course, we could make a real effort to reduce domestic cats into the wild landscape, and to rehome cats, but that would take pols who care.
And something about coyotes?
