If there is loose stool or excessive, too little or no urine, it indicates that the cat's health is abnormal.

8. Cats eat it every day under normal circumstances. Patrol your territory and check the room for signs of other cat activity. If you find that the cat is not patrolling or inspecting, it may be caused by the cat being sick, and you need to be more vigilant.
