A reptile that eats whole prey is getting a nutritionally complete meal in one go, provided the size of that meal is matched to the animal eating it — too big and it goes uneaten, too small and it isn't worth the effort of catching. Monkfield's small mice are sized to sit in that middle ground.

These are frozen whole mice, sold in a pack of five, each weighing 10-15g. Our analysis gives moisture at 67%, protein at 21% and fat content at 9%.

On defrosting. Monkfield's instruction is to defrost thoroughly at room temperature on newspaper or kitchen towel, away from food preparation surfaces, and never in warm water or a microwave. Hands should be washed thoroughly before and after handling. That's a food safety step worth following exactly, not a suggestion.

Who it's for: keepers of small reptiles whose feeding size falls in the small-mouse bracket — check your own animal's needs before stepping up or down a size.
