Feeding whole prey means the size has to match the animal doing the eating, and Monkfield's own weight chart puts a "Mouse Crawler" specifically at 6-9g — a step up from a Fluff and a step down from a Small Mouse — rather than a vague size name with nothing behind it.

Monkfield's Crawler mice come frozen, 25 to a pack, at 6-9g each per their own grading chart. Their analysis shows 67% moisture, 21% protein and 9% fat. All mice come from a European rodent farm, are humanely euthanised under government-set guidelines, and Monkfield is DEFRA-licensed for trade distribution.

• 25-pack, frozen
• Mouse Crawler size, 6-9g each per Monkfield's own chart
• Moisture 67%, protein 21%, fat content 9%
• Monkfield are DEFRA-licensed for distribution to the trade
• Defrost naturally at room temperature only — never in warm water or a microwave

One thing worth knowing. Getting the prey size right matters more with reptiles than with almost any other feeding decision, so checking that a 6-9g mouse is genuinely the right size for your specific animal — rather than just matching a name like "Crawler" — is worth doing before you order a 25-pack.

Who it's for: reptile keepers feeding whole prey who need a specific, known weight band for a smaller animal than a Small or Medium mouse would suit, bought in bulk.
