SiarFrozen™ Large Weaner Rats (60g–90g) – 10 Pack Bulk Frozen Feed

The high-performance growth stage. SiarFrozen™ Large Weaner Rats are specifically graded for sub-adult pythons, boas, and monitors that require a more substantial caloric intake to support their secondary growth phase. At a weight range of 60g to 90g, these rats provide a dense concentration of muscle tissue and fully formed skeletal minerals, offering far superior nutrition to multiple smaller mice.

Why Choose SiarFrozen™ Large Weaner Rats?

• Optimised Growth Profile: Large weaners offer the perfect balance of protein and calcium for sub-adult reptiles, ensuring steady development of bone density and muscle mass.
• Efficient Feeding: Ideal for larger juvenile Royal Pythons and Boa Constrictors — feeding one large weaner instead of several mice reduces digestive stress and mimics natural wild feeding patterns.
• Nutrient Preservation: Our flash-freezing process locks in the essential vitamins found in the internal organs, vital for the long-term metabolic health of your predator.
• Ethical & Hygienic: Raised in a controlled environment to ensure no parasites or pathogens. Every rat is hand-selected to meet our strict weight requirements.
• Professional 10-Pack: Vacuum-sealed to prevent freezer burn, ensuring the last rat in the pack is as fresh as the first.

Feeding & Storage

• Storage: Keep frozen at -18°C.
• Thawing: Thaw thoroughly in a refrigerator overnight or in a sealed bag in lukewarm water. Ensure the core is fully thawed. Warm the head slightly (35°C) before feeding to trigger heat-sensing pits in pythons and boas.
• Safety: Use feeding tongs to maintain a safe distance and ensure hygiene. Sanitise all tools and surfaces after use.
