This article from Listverse even tells of an animal that seems able to predict death. That's a scary talent if you ask me.
Cats
Cat owners have been reporting that their pets have healing powers for ages. While cats do not have the ability to cure sickness, they are definitely capable of detecting it.
Diseases cause chemical changes in the body, and cats use their acute sense of smell to identify whether someone is sick or not. Our feline friends gather more information by sensing changes in our mood and behavior. They can also detect illness in other animals.
One cat has even “predicted” 25 deaths in a nursing home. Although unfriendly by nature, Oscar the cat displayed sudden affection toward multiple residents who were close to death.
Experts hypothesize that the cat can smell and sense organs shutting down. Do not hurry to schedule a doctor’s appointment if your cat suddenly sits in your lap, though. Even the most independent and egoistic beings want affection occasionally.
I have noticed my cats seem to pay more attention to me when I'm not feeling well. Then again, guess it could be because their feeding schedule is a little off at that time. Yeah, that's more likely.
Coffee out on the patio this morning. Sunshine is available for those in need.
