Do Cats Know When You Are Dying?

It has been noted that some cats may know when a person is dying, although this isn't something attributed to every cat.

How Do They Do It?

Some feel a cat's keen sense of smell would allow him to detect chemical changes within the body that signal impending death. A similar theory is applied to explain how cats have successfully detected cancer in their owners.

Can Your Cat Predict Death? 

Probably not, but you never know. That being said, it isn't something that has been studied, so few details are available. If you notice your cat hanging around you more than normal, don't panic. It probably just means he's vying for extra treats or snuggles rather than signaling your impending doom.
