In the process of realizing the present invention, the inventor found that when pets are sick, the concentration of molecules emitted by their excrement (such as the feces that have just been excreted) will change, especially for some medical diseases, such as gastrointestinal diseases, which have just been excreted. The concentration of molecules emitted by feces changes more obviously. For example, when a pet cat has gastrointestinal discomfort, within a certain period of time after the feces are produced, the concentration of odorous molecules emitted by the feces is much greater than the concentration of odorous molecules emitted by the feces in a healthy state. Using these similar differences, within a certain period of time after the pet's excrement, we can more easily identify whether the pet is sick. The term "pet" commonly used in the present invention mainly refers to common cats or canines.
