How is Hailey's household different than the Brophy's in the novel, Word of Mouse?

Hailey’s household is the opposite of the Brophy’s in that it offers wholesome food, is clean and has a dog and a cat that do not attack mice. In addition it has a human who is different herself and cares about the welfare of the mice. While the Brophy household is a mess and full of junk food, Hailey’s house has classic cakes and sweets and even offers Isaiah the opportunity to choose fruit as opposed to cake. In addition, while Hailey is initially shocked to see Isaiah, she is kind to animals of all types and generates a sense of harmony as shown by the fact that her dog and cat coexist with each other and do not bother Isaiah or Mikayla.
