I was extremely concerned to see that you listed outdoor roaming as a new-owner's mistake.
Here in the UK we consider it cruel to keep a cat indoors, especially if it is kept alone, without another cat. Indeed, the Cats' Protection League will generally not rehome to flats or houses without gardens.
Perhaps in America the situation is different to in the UK. I would like to see a caveat added to your article, as I would never consider keeping a cat enclosed permanently.
I simply can't tell my readers that it's "okay," or even preferable, to let them roam freely; that was the reason for my article on safe alternatives, which includes garden-type enclosures, so that cats can enjoy the best of both worlds.
My own cats enjoy playing outdoors, in our enclosed courtyard, with either me or my adult son in close attendance. They don't suffer at all from not being allowed to roam into neighbor's yards, or out into the street.
If one of us can't be outside with them to supervise at all times, they stay indoors.
