Your cat doesn't know which species are of least concern, and you certainly aren't seeing every bird or small mammal or reptile your cat kills for fun.

I recently took a course on ornithology and was stunned by how difficult a bird's life is from the migrations, predations, building collisions, and the sheer amount of work they invest in nesting and raising their young. It's easy to take them for granted until you actually understand what they go through just to exist, unlike a pampered cat who gets to kill for sport.

Cat owners who allow their cats outdoors are being cruel to birds and small animals, period. A bell on your cat's collar doesn't make much difference. There's no way to wiggle out of this moral dilemma. If you love nature and want it balanced and protected, then keep your cat indoors. Or, if you can, train your cat to kill only invasive species.

Of course they don't know which is of least concern, but by and large I do see everything they kill because they bring it home and I have to clean it up. It is in their nature to bring it home.

Bells and other deterrents absolutely do make a difference (https://www.frontiersin.org/articles/10.3389/fevo.2022.85044...)

There's barely any species of concern in urban environments anymore, because:

* Industrial run-off * Habitat destruction * Roads and highways with vehicles * Air pollution * Light pollution * Poisons * Electrocution from power lines * Buildings with glass (actual a #2 killer of birds!) * Hunting (both legal and illegal)

Domestic cats are merely a cherry on top of the myriad of environmental mistakes humans have made in the name of progress.

They are simply acting on instinct and trying to be happy in a world of human creation.

If you truly care about birds I would urge you to:

* stop driving * use no lights past dusk * not use or consume any product that contributes to air pollution * not use any power grid that uses power lines * not use any building with glass * not consume any poultry

You forget that cats aren't always 100% in their kill rates. They also maim many critters who die sooner or later from their injuries.

So while you pet and play with Fluffy that evening, the mother bird she maimed earlier that day can no longer make ~100 trips a day to feed its hatchings. She tries, but can only manage a dozen or so trips. They slowly starve over the next few days despite the mother's desperate attempts.

That bird survived all the other leading causes of bird mortality, but not Fluffy. And Fluffy gets a few more bonus kills when the hatchlings expire.

I'm curious what would you do if people had a new breed of small domesticated dog that is efficient at killing outdoor cats, and those people let that dog roam like a cat?

Given that your cat is out there doing his thing, this new breed of outdoor dog is also out there doing his thing. As you said, they are simply acting on instinct and trying to be happy in a world of human creation.

His owners think he's a person. It would be cruel to lock him up all day.

But one of these dogs swiftly kills your outdoor cat. And your next cat. In fact, they're becoming the leading cause of death among outdoor cats, seconded only by cars.

Would you a) demand that dog breed not be allowed to roam because it harms cats, b) keep your next cat indoors, or c) ?
