Most cat owners I know have inside only cats, as do I. I do know of 3 cats that roam my neighborhood, they could be from quite far away as outdoor cats have a large range.

I guess anecdotes from you or I isn't really telling if an indoor or outdoor majority of cat ownership is "unrealistic". Maybe we need a study :p

Do outside cat owners generally let their cats inside their home?

Doesn’t matter, they’re domestic cats and you already explained a circumstance where they could expose visitors and owners. Half the year here is a hospitable climate for outdoor recreation and cat survival. Half of it isn’t. I have seen these cats for multiple years so unless they have an outdoor cat house (something I have never seen in my life) then I suspect they come inside.

The ratio of cat owners with outdoor cats is irrelevant. They exist and they are common. That’s enough to sink your assertions.

It's extremely relevant when talking about a large enough scale of infection to support the attractiveness causation hypothesis posed by GP.

Outdoor cats generally stay underneath the house / porches, cars, etc. during cold or especially hot weather.

I'm disputing the above proposed hypothesis on the grounds I don't think it's common enough occurrence and we're lacking information.
