Cats are for killing birds - that's their niche. No more wrong than birds doing what birds do.

And face it, every bird pair has half a dozen chicks each year. Next year the bird population is about the same. That means, most new birds are going to die in the first year. Cats are just a part of that.

Domestic cats are an invasive species. They're not a natural part of the food chain, they're not doing any good by killing or even eating what they kill, they just do it for fun. They basically have no predators because they live where we live, and we chase off or kill predators.

Depending where you live cats have multiple predators.

Same can be said for humans.

There were some 500 species of cat, spread all over the world, when humans arrived. You cannot find a niche where cats are 'invasive'. How they kill, and what they eat or don't eat, is entirely up to the cat, not some misplaced human emotion about right and wrong.
