While the misanthropy is compelling, and bell collars slightly reduce hunting success for (invasive, feral) cats, literally nothing else in your comment correct.

Concern for native birds and small mammals which are a keystone part of our ecosystems is not futile. They support literally everything required for human survival (carbon cycle, water, cycle, nitrogen cycle, pollination, sea dispersal, pollution control, etc) directly, and indirectly by their behaviors which have coevolved for millions of years. Invasive, feral cats, just like humans have only been here for a very short window of time, and while there are still native birds and mammals and plants left to care for, we can and should support them by minimizing the wonton carnage and death which we unleash each year. You’re probably aware that in North America alone feral cats kill between 10 and 30 billion native birds and small mammals a year. Euthanasia instead of trap neuter release is not a sailed ship. Planting native (human intervention) and undoing the lawns (human intervention) that have destroyed our native ecosystems is not a sailed ship. There is hope and it is exciting to work towards this in your own community and I hope you come to see that. The results (insects return, the soil enriches and traps carbon, and birds you've never seen before sing on your back porch in the morning) are nearly immediate and heartwarming

and how many of those birds and mammals were old and ill and would be killed by other predators in similar situation in non-developed areas? Why didn't you specify that comparative number? May be because that would have shown that the cats are just doing the job of other predators pushed out by humans?

Btw, the cats kill up to 4 billion birds annually. At the same time 3.5 billion birds die hitting glass of the buildings. Cats kill old/ill. The birds hitting building aren't majority old/ill. Thus killings by cats are mostly beneficial to the bird species while glass buildings make tremendous damage to the bird species.

What evidence do you have that the birds killed by cats are mainly old or ill?

Cats being an invasive species in most places on earth means that most bird species have not evolved with them as a natural predator, and so are at an innate disadvantage.

And yes, birds hitting man made structures is a major problem. There can be two bad things at once. Just because there are two bad things doesn't mean we give up tackling one or the other.

Do you have a citation for this? Are you comparing North American cat deaths to worldwide building collisions? Estimates I'm seeing of North American center around 600 million, a far cry from deaths due to cats.
