• Whole prey, not processed — a complete, balanced meal with fur, bone and organs intact, exactly as an obligate carnivore is built to eat.
• Adult size grade — approximately 18–30 g, the step up from Hoppers for reptiles that have outgrown smaller prey.
• Frozen fresh, not freeze-dried — retains natural moisture and nutrition that freeze-dried prey loses.
• Consistent sizing within the grade — makes it easier to track how much your animal is eating over time.
• Sold individually — buy exactly the number you need for your feeding schedule.

Mouse feeders are graded by weight, not just name, because "Adult" can mean a different size from one supplier to the next. As a general guide, choose a mouse close to the width of the thickest part of your snake's body — if you're unsure, size down rather than up to avoid a difficult feed or regurgitation.

This listing is the Adult grade. We also stock Pinkie, Fuzzy, Hopper and Jumbo mice separately.

Keep frozen at -18°C or below until you're ready to feed. Thaw fully before offering — either in the fridge for several hours, or sealed in a bag and submerged in cool water until soft all the way through, including the body cavity. Never microwave or use hot water, and never feed a mouse that's still cold or partly frozen in the middle.

Warm to roughly room temperature before offering for the best feeding response. Never refreeze a mouse once it has thawed — if your reptile doesn't take it, discard it.

Suitable for: adult colubrid snakes, smaller pythons and boas, monitors and other carnivorous reptiles, plus birds of prey, sized appropriately to the Adult grade.

Not suitable for: hatchlings or small juvenile reptiles — an Adult mouse is too large a meal for them and risks regurgitation. Choose a Pinkie, Fuzzy or Hopper instead. Also not suitable for herbivorous or insectivorous reptiles.

How do I know if my snake needs Adult or Jumbo mice?

Compare the mouse to the thickest part of your snake's body — it should be roughly the same width. If Adult mice are still a comfortable, complete meal, stay at this size; move up to Jumbo only once Adult mice stop being enough.

Can I refreeze a mouse if my reptile doesn't eat it?

No — once a frozen mouse has thawed it must be fed or discarded. Refreezing thawed prey is a food-safety risk.

Do I need to warm the mouse before feeding?

Full thawing to around room temperature gives the best feeding response from most snakes, which key in on warmth as well as movement and scent.

Is whole prey better than processed reptile food?

For obligate carnivores like snakes and monitors, whole prey provides a complete, balanced diet — bones for calcium, organs for micronutrients, and fur for roughage — that's difficult to replicate in a processed food.
