What breed is a hairless rat? - briefly
Hairless rats are not a separate breed; they are a genetic mutation of the common fancy rat (Rattus norvegicus) that produces a fur‑less coat. They are classified as the “hairless” or “nude” variety within that species.
What breed is a hairless rat? - in detail
Hairless rats belong to the fancy‑rat category rather than a distinct breed. The hairless appearance results from a recessive mutation (the “nude” gene) that eliminates most of the fur, leaving a thin, almost naked skin. This mutation is maintained through selective breeding of carriers, so all hairless individuals are homozygous for the gene.
Key characteristics:
- Skin is pink or lightly pigmented, requiring protection from drafts and ultraviolet light.
- Body shape, size, and temperament match those of standard fancy rats; they are typically 150–250 g and display the same social behavior.
- Breeding requires pairing two hairless rats or a hairless with a carrier to guarantee offspring with the trait.
- Health concerns include increased susceptibility to skin injuries, dehydration, and temperature regulation problems; regular monitoring of hydration and ambient temperature is essential.
- Lifespan mirrors that of other fancy rats, averaging 2–3 years when proper care is provided.
Care guidelines:
- Maintain ambient temperature between 20 °C and 24 °C to prevent hypothermia.
- Provide a humidified environment to avoid skin dryness.
- Use soft bedding (e.g., shredded paper) that does not irritate the skin.
- Apply a veterinary‑approved skin moisturizer if dryness appears.
- Schedule routine veterinary examinations to detect early signs of dermatitis or respiratory issues.
Availability is limited to specialty breeders who focus on the hairless variety. Prospective owners should verify the breeder’s health‑screening practices and request documentation of the rats’ lineage to ensure genetic integrity.
