Because small rodents are common prey of many snakes, and because nearly all snakes swallow their prey whole, we explored four methods for determining the ingestible size (the smallest cross\u2010sectional area that the largest part of the rodent can be made into without breaking bones or dislocating joints) of 100 intact rodents, including 50 <jats:italic>Mus<\/jats:italic><jats:italic>musculus<\/jats:italic> and 50 <jats:italic>Rattus norvegicus<\/jats:italic>. Cross\u2010sectional areas derived from maximal height and width of specimens at rest or the same specimens wrapped snout to pelvic girdle are roughly 1.5\u00d7 higher than areas calculated either by the height and width of the same specimens rolled into cylinders or by volumetric displacement. Rolling rodents into cylinders reduces cross\u2010sectional area by straightening the vertebral column, lengthening the abdominal cavity, elevating the sternum, compressing the thoracic cavity, and protracting the shoulder joint, that is, changes similar to those seen in rodents eaten by snakes. Reduced major axis regression of the smallest attainable cross\u2010sectional area, <jats:italic>y<\/jats:italic>, on mass, <jats:italic>x<\/jats:italic>, shows that <jats:italic>y<\/jats:italic> (in log mm<jats:sup>2<\/jats:sup>) approximates 1.53<jats:italic>x<\/jats:italic> (in log grams)<jats:sup>0.69<\/jats:sup> for rats and 1.63<jats:italic>x<\/jats:italic><jats:sup>0.64<\/jats:sup> for mice. Our results suggest that visual cues provided by live rodents might lead most predators, like snakes, to overestimate ingestible size and hence rarely attack prey too large to ingest. J.
