||The Masters family is moving to a new house. They
have a dog, a cat, and a pet mouse, but the animals
don't get along in the car, so they can take only
one at a time.
Then there are other problems. They can't leave
the dog alone with the cat, because the dog chases
the cat if no one is watching. And they can't
leave the cat and the mouse together, because...well,
you know what would happen if they did.
How can the Masters family get all three of their
pets to their new house?
