Generally, a cat will die if it doesn't eat or drink for about a week, depending mainly on the cat's constitution. Immature cats or cats with poor health may starve to death after 5 days without food or water, but even cats with good health can only survive for a maximum of a week.



Therefore, if the owner is going away for an extended period, they should board their cat at a friend's house or a pet store to prevent any accidents from happening to the cat. If the trip is for 3-4 days, be sure to prepare plenty of food and water for the cat.
