Almost like it’s in their nature to explore and naturally have territories of up to 10 acres and so are not best suited to being strictly indoor pets

Cats are an invasive species and kill over 15 billion birds and small mammals per year. There’s nothing ‘natural’ about that.

Your cats freedom means the ecological destruction of your surroundings. Choose wisely.

‘Invasive’

It’s been five hundred years. Pretty sure this is a pointless distinction by now

it doesn’t matter how long they’ve been somewhere. if they were brought by humans, they’re invasive

That’s not how invasive species work. 500 years is nothing on the evolutionary time scale.

Also, cats have been widespread for about 2000 years in the old world, not 500.
