Yes, pets have been known to detect illnesses in humans due to their keen sense of smell and ability to pick up on changes in their owners' behavior and body chemistry. Dogs, for example, have been trained to detect various medical conditions such as diabetes, cancer, and seizures in humans. Cats and other animals may also exhibit changes in behavior or show signs of distress when their owners are ill. It's important to consult with a healthcare professional for a proper diagnosis, but many pet owners have reported their pets alerting them to health issues.
