I’ve got three innies and one in/out. We will never have another outie. But this one is a sprayer and has never lived indoors. When it’s cold, he sleeps in the laundry room. We all get along famously.
Iteki- sure I agree that farm cats are the exception- they have a job- keeping rodents down. And, of course, in a rural area, they have far less risk of getting run over, or of contacting other cats with nasty diseases- like “kitty aids”.
But for cities or suburban areas- keep your cat indoors. Better for the cat, better for you (no fleas!), better for the environment. And not cruel at all. My cats never go outside (they have a small fenced patio are, however), and they are healthy & happy- and the last two don’t even know what a flea IS.
Sorry, I was uncler, by farm cats I mean moggies, mongrel cats. They are called “farmcats” in Swedish. Just plain old cat-cats 
I lived with my cats in a suburban area with small front and back gardens and both residential and main roads.
Sorry about any confusion.
Sorry, I guess I was a little harsh.
It was just the whole “politically incorrect” remark that I overreacted to.
I will say that I just feel safer knowing my cats are indoors, and comparing them with neighbor cats that go outdoors, they seem healthier.
And spoiled rotten.
My indoor/outdoor cat doesn’t have fleas either. They make great medicine for that now.
My parents had five indoor/outdoor cats (not all at the same time) while I was growing up. Four disappeared without a trace, one was found dead in the driveway. Of the four that disappeared, all were less than three years old (and one was less than a year).
