I'm not even talking about the controversy about cat impact on wildlife; I'm referring to the statistical life expectancy of outdoor cats in the US. If anyone isn't satisfied with the one link I provided, I can find more: outdoor feline life expectancy is statistically drastically shorter than strictly indoor life expectancy. All I did was list the risks - the truth is in the statistics. But everyone who has that one outdoor cat that lived to 27 thinks their anecdotal experience trumps science 🙄.

I can't speak to Norway. Maybe the feline diseases aren't rampant there yet. Maybe the Norwegians have long ago exterminated all of their mid-range predators in populated areas. I doubt grandparent up there lives in a place where wolves are roaming around freely. You have coyotes or something similar there in your rural communities, my Norwegian friend from a couple comments up? Maybe the fact that few, if any, European countries have anything like the US car culture keeps streets safer for loose pets.

But in the US, letting cats outdoors statistically reduces their life expectancies. That's not my opinion; it's in the data.
