From the New England Journal of Medicine, an amazing cat story.

I have a family friend who has suffered from 3 strokes, 2 mild and one severe.

His family says that their cat predicted it all 3 times. He is normally a very low key cat, sleeps all the time, sits and watches the world go by.

But the day before each stroke happened, he would be very agitated, would follow him around, and meow all the time.
