Question

Consider the puzzle about a child traveling with a dog, a cat, and a mouse. The child walks up to a river with a dangerously narrow bridge on it, and the child quickly realizes that his/her only chance to get all of the animals across the bridge safely is to carry them one at a time.

• Of course, the dog and cat should not be left alone together at any point of this process.

• Of course, the cat and mouse should not be left alone together at any point of this process.  

In the space below, what steps should the child take to get all of the animals across the bridge safely?
