"What if you had a family of five is on vacation in the Netherlands with their five pet cats (each person owns a cat). To get to the place they want to have lunch, they must cross a canal, but the only way to get to the other side is to a small boat. Unfortunately, the boat can only hold three things, regardless of size. The cats are very anxious creatures and cannot tolerate another person, even for a moment, unless its owner is present. Left alone, the cats get along very well with each other. One of the cats is a tiger and has been trained to operate a boat, but the other cats lack this ability, All five family members can operate the boat. How can the five family members and their five cats cross the canal?"
