* If you poke around the internet, you’ll find plenty of people talking about how their cats alerted to their low blood sugar. A news report on YouTube features a man who says his cat, Oz, saved his life three times, including the time he was in a diabetic coma on the living room floor. Oz ran and woke up the man’s girlfriend, who called 9-1-1. Despite the cat’s lifesaving acts, the man told the reporter that Oz is not the “brightest brick in the wall.” In the video, Oz didn’t so much as give him a dirty look, much less scratch him.
