There are many reasons why cats have soft stools. Generally, factors such as eating too much, eating too quickly, or eating overly oily food can lead to indigestion and subsequently soft stools. Parasite infections can directly affect a cat's digestive system, disrupting gastrointestinal function and causing soft stools. Cats may also be allergic or intolerant to certain foods, such as milk or grains, which can also lead to soft stools.

Furthermore, cat owners tend to be more empathetic and loving, which can lower stress levels. When petting a cat, a pet owner's blood pressure and pulse will noticeably decrease and become more peaceful. Therefore, it makes sense that owning a cat can help relieve stress and anxiety.
