Man we already got all the fuckin cats we need and the ones that are outdoors are a nuisance that murders the shit out of birds and other native wildlife.

If someone is just letting their cat run around freely without any way of knowing the cat has an "owner" - I say get them neutered or spayed. At least it'll reduce the number of kittens and help with feral cat control.

I say this as someone who's had multiple pet cats.

Edit: to be clear I also am nice and friendly to the outdoor cats I see but it is kind of irresponsible to just let them run free in suburbia. Maybe out in the countryside I could see. But cats will kill for fun so it's not like keeping them well fed stops the whole bird murder machine problem.
