Many people are finding that the gender in which they were raised is not the one that they are comfortable with. Whether they are changing from male to female or female to male, these changes affect everybody in the person's life. The changes are required in order for the person to live fully and completely as their true selves.

How does one explain to a young child why their loved one is changing their gender? "Muffy was Fluffy" was written to show young children how a beloved pet, Fluffy, is not comfortable with the way she was born and in order to be truly happy, she must change into Muffy, the type of pet she was meant to be.
