Why Choose SiarFrozen™ Large Mice?

• Peak Nutritional Density: As fully mature adults, these mice provide the highest levels of calcium and phosphorus available in the mouse life cycle, supporting long-term bone density.
• Efficient Feeding: One large mouse provides a significant caloric payload, allowing you to feed less frequently while meeting all the metabolic requirements of an active adult reptile.
• Biologically Complete: Flash-frozen whole to preserve natural enzymes, vitamins, and minerals, ensuring your pet receives a diet that replicates their natural wild intake.
• Hygienic & Pathogen-Free: Raised in bio-secure, climate-controlled facilities. Our rapid freezing process eliminates the risks associated with parasites and live-feeding injuries.
• Professional 10-Pack: Packaged for easy storage and portion control, ensuring peak freshness for every meal.

Feeding & Storage

• Thawing: Place the required number in a sealed bag and thaw in lukewarm water for approximately 30 minutes. Ensure the mouse is fully soft to the core and has reached room temperature (or slightly above) before offering it to your pet.
