Feral cats have been directly implicated in the extinction of a number of birds, particularly on islands. Some birds nest ON THE GROUND and display "injured" behavior to lure predators (cats) away from their young.

Yes, you can trace it all back to humans. (Humans introduced feral cats after all.) But we have to work with the pieces we have. And when you have an introduced apex predator wiping out huge swaths of native mammals and birds, AND serving as a major disease vector, well... you tell me what to do. Get rid of the cats. It's that simple.

(Incidentally, there is quite a lot of evidence that these crazy "cat people" are carries of toxoplasmosis themselves... seriously. The changes in behavior after infection are bizarre, and lead to the many "crazy cat ladies" locked in their house with hundreds of cats and their feces. Just like it drives rats to cat feces (true), it seems to have similar effect on some humans. Search for toxoplasmosis on Google.)

This is idiotic.

Feral cats are the main vector for TOXOPLASMOSIS. And that disease can spread to humans, and it is lifelong and leads to bizarre changes in behavior. (DO a search for toxoplasmosis if you don't believe me.)

TNR is a waste of time. There are no "studies" that prove it works. It doesn't, because it assumes that if you euthanize cats, some other cats will step in. Well, that is true, save for the fact that you have X less cats.

Toxoplasmosis is killing wildlife across the country, particularly wild otter populations on the California coast.

Feral cats kills endangered birds in the millions. They are an introduced, apex predator. They should be euthanized.
