A magical moonlit place where tiny creatures live and gather

Established in 2022, I focus on producing healthy, well-socialized mice with exceptional temperament, raised through ethical breeding practices and science-based husbandry.
Ethereal Moon Mousery is more than a breeding program. It’s a hub for mouse genetics, behavior, and advanced husbandry, created for both breeders and passionate mouse enthusiasts.
My work blends selective breeding, research, and storytelling to create mice that are as thoughtfully developed as they are beautiful.
This work extends into Ethereal Moonlit Studios, where I create custom artwork designed to reflect each mouse’s unique story and presence.
I also serve as Vice President of the Fancy Mouse Breeders Association, contributing to the broader fancy mouse community and advancing ethical, informed breeding practices.
The dumbo line focuses on the dumbo ear type, a structural trait affecting ear placement and skull shape.
This project is currently under study and development, with emphasis on health, structure, and long term stability.
Dumbo mice are not available to the public at this time while research and evaluation are ongoing.

The sable line in this mousery does not represent traditional sable (dominant yellow with tan). Instead, these mice are recessive yellow based with expression of the umbrous gene, creating deeper shading and a more muted, complex tone.
My focus is on developing consistent color depth, clarity, and overall health while continuing to study and refine this expression.

The Splash Line focuses on bold, high-contrast c dilute patterning paired with rich base colors. I selectively breed for clean markings, healthy structure, and sweet, confident temperaments. These mice are raised with ethical husbandry and careful tracking to support both beauty and long-term wellness.

The Angora Line features the long-haired (Fgf5 angora) coat type, emphasizing soft texture, whimsical looks, and a calm, friendly temperament. My goal is to produce healthy, well-maintained angora coats without compromising overall welfare. These mice are socialized from a young age and raised with detailed observation to support comfort and quality of life.
Please note: We are limited on the angora variety at this time.

The X-Black Line is dedicated to producing deep, sleek, high-quality black coats with strong pigment and minimal molting. This line is built around careful selection for coat clarity, body type, and strong temperament. My focus is on maintaining that “ink-black” look while keeping genetic diversity and health at the center of every pairing.






Hi, I’m Indigo Hart, a fancy mouse breeder with a deep passion for genetics, husbandry, and science-based care.
With nearly five years of hands-on experience, I focus on producing healthy, well-socialized mice while continually refining my lines through ethical, intentional breeding.
I’m especially drawn to how genetics shape not only coat color and texture, but also behavior and temperament, because structure and personality are just as important as appearance.
Outside of breeding, I work in art and photography, which influences the way I see and present my mice. To me, each one is not just carefully bred, but thoughtfully observed, and often, artistically expressed.
This space is where I share my work, research, and passion with others who love mice, and where you can connect with me as a fellow breeder or for pet home placement.
