Cat owners who let their cats roam are irresponsible and entitled
You’re uninformed. Cats co-evolved with humans to serve a job (pest control, in exchange for safety and the occasional bit of food). There have only been fully indoor cats for a few hundred years. Not all cats have to have a job, but some WANT one, just like dogs. We should let them.
My cat is angry with me if I don’t let him spend at least 12 hours a day roaming and catching bugs and mice. He has neighbor cat friends that he goes to see. Why would I deprive him of that?
The danger isn’t to the cats, it’s to everything else. Ecologically speaking, cats are an invasive apex predator. They absolutely wreak havoc on local bird populations.
Cats aren’t apex predators. But yes, they can be quite damaging in araes where they are invasive.
