You are confusing feral cats and pet cats. Domestic cats, if let outside (not a good idea) generally kill weak and diseased rodents and birds. The feral cats help curb rat and rabbit populations.

If dogs were left to be feral they will pack together and attack humans. I could tell you stories about what I saw dogs eating in Iraq (it's what you think).

Agree, but not all house cats are not kept in house only. See plenty prowling at nights with little collars on. How many feral dogs do you see around squares? That would be none. How may feral cats see around squares….
I disagree that house cats only kill diseased birds and rodents.

Feral cats eat what they kill. House cats kill but seldom eat their kill. As for killing mostly weak or deseased, that is a canine trait, seen in wolves pack hunting separating the old, young, sick or weak. Wild cats hunt by themselves and kill what ever they can to survive.
House cats do pose a threat to wild life when they are out and about, doing what cats do, hunt and kill. They are not bad, it is their .

Someone / anyone grousing about a cat / dog reducing the wildlife population should take a walk along Corbin Trail and count the gators.

We have never allowed any of our cats outside. If you see a cat out and about with a collar take a pic, most likely lost.
Our 4 pound declawed Himalayan wouldn’t make it outside. Has zero skills to hunt, track, or play with a toy.

She does beg, sit up, and comes when you whistle. Sits at the door when she hears the garage door open waiting for you. She is so tiny jumping on our bed is out of the question. Just turned 11, still looks like a kitten.

Alligators need to eat, too. If house pets reduce the items on natures buffet, then don't be upset if the gator invites "fluffy" for dinner.
