• Largest size on the ladder — XL jumbo sits at the top of the feeder mouse size range, typically 30–45 g and up.
• Whole animal, single ingredient — nothing added, nothing removed.
• Frozen, not live — no feeding-response risk to your reptile and nothing to house or care for before use.
• Consistent sizing — graded to the XL jumbo class so portions stay predictable as you plan feeds.

Feeder mice are graded by size, not age alone. A common rule of thumb is to choose a mouse close to the widest part of the reptile's body — go smaller if you're unsure, since undersized prey is safer than oversized prey.

These weight bands are the widely used industry standard for feeder mouse grading and are a guide, not a guarantee — individual animals vary, and at the jumbo end especially, weight can run higher than the range shown. We currently stock pinkie, weaner and XL jumbo; ask in-store if you need fuzzie, hopper or standard adult sizes.

100% whole mouse, frozen. No additives, colours, preservatives or fillers — this is an intact animal, not a formulated food.

A guaranteed analysis (crude protein, fat, fibre, moisture, ash) is not published for whole-prey items the way it is for manufactured pellets or flakes, because there is no manufacturer formulation to declare. Whole prey supplies muscle, organ, bone and fur in natural proportions, which is the basis of a whole-prey feeding diet for carnivorous reptiles.

• Suitable for: larger adult snakes that need a bigger feed than a standard adult mouse provides.
• Not suitable for: hatchlings, juveniles or smaller adult reptiles — an XL jumbo is oversized for them and increases the risk of regurgitation. Step down the ladder above instead.

Keep frozen until you're ready to feed. Because of the larger size, allow extra time to thaw: a sealed bag in the fridge overnight, or room-temperature water changed every 10–15 minutes until soft all the way through the body — never a microwave, which cooks prey unevenly. Warm the thawed mouse in warm water for a few minutes before offering it, as many reptiles respond better to a warm feed. Never refreeze a thawed mouse — feed it the same day or discard it.

Treat frozen prey like raw meat: thaw it separately from human food, wash your hands and any tongs or containers after handling, and disinfect the thawing area. Discard any uneaten thawed prey rather than offering it to another animal.

• Zoo Med Plastic Feeding Tongs — essential at this size for safe handling, and lets you add a little movement to trigger a feeding response.

This is a frozen product and ships and is stored frozen. There's no manufacturer warranty on a food item as such — the consumer guarantee under Australian Consumer Law that the product is of acceptable quality and matches its description still applies. Transfer it to your own freezer as soon as it arrives.

How many mice come in a pack?

One mouse per pack, sold individually so you can buy exactly the number of feeds you need.

What size reptile is an XL jumbo mouse for?

Larger adult snakes whose body width matches or exceeds a standard adult mouse — check against the size table above before buying.

Can I refreeze a thawed XL jumbo?

No. Once it's thawed, feed it the same day or discard it.

Should I feed an XL jumbo mouse or move to rats?

That depends on your snake's species and size rather than the mouse alone — if you're unsure, ask our team before stepping up to a different prey animal.
