Cats generally won’t ask for help if they are hungry for a day. Cats can generally be hungry for about three days. If a cat feels hungry, it will usually look for food on its own. If it really can’t find anything to eat, it may also look for its owner in front of the owner. Calling or rubbing back and forth, so the specific situation depends on the cat's own situation.
Tips:
It is best not to let the cat starve for too long. If the cat is hungry often, its resistance may decrease. In severe cases, it can also cause gastrointestinal diseases.
