According to National Geographic, there has been a study on stressed cats. That much is true. Unfortunately, the results have been misreported. What the study really says is that if a cat is already anxious of something, you can pick up on that when you stroke it.
These cats aren't stressed because they are being stroked. They're stressed because of something else in their lives, and a twitchy, nervous reaction to being touched might indicate that something is wrong.
Cats are experts in hiding their feelings, and any clue to something being wrong is valuable.
A cat that spends most of its time hiding might be stressed. A kitty doing that can't relax unless it is in an easily defendable position.
