Feeding a whole prey item rather than a processed food is the point of reptile feeding for most keepers, and getting the size right matters more here than with almost any other pet food, because too big a rat is a genuine risk to a snake or monitor rather than just wasted food.

Monkfield grade their rats by weight: Small Rats fall in the 101-150g range, Medium Rats 151-250g and Large Rats 251-355g, and this listing covers all three, sold in packs of five. Across the range, Monkfield's analysis shows 64% moisture, 14% protein and 5% fat. All rats come from a European rodent farm, are humanely euthanised under government-set guidelines, and Monkfield is DEFRA-licensed for trade distribution.

• 5-pack, available in Small (101-150g), Medium (151-250g) or Large (251-355g)

One thing worth knowing. Feeding the wrong prey size is a real risk with reptiles — too large a rat for the animal can cause serious harm — so matching the weight band to what your reptile actually needs, rather than guessing from "Small, Medium or Large" alone, is worth doing properly before you order.

Who it's for: reptile keepers feeding whole prey who need a specific, known weight band rather than a vague size description, and want to buy in a 5-pack rather than one at a time.
