Starch, as fedEstimated, not measured. It is what is left of the guaranteed analysis once protein, fat, fiber and moisture are taken out, with ash assumed at 6%. That leftover is mostly starch but also carries sugars and the fiber a crude-fiber test misses, so read it as a close estimate rather than an exact figure.

Line figures are averages over every kibble recipe we review from that line, with the lowest and highest recipe underneath. Wet food, toppers and prescription diets are left out so the numbers compare like with like. Everything is as fed, the way the bag prints it; the switch above the table shows protein and fat on a dry matter basis instead. Why we use as fed. The price per pound is an estimate: the median of each recipe's lowest price per pound across the bag sizes and US retailers our price checks found, so a single bag can cost more or less. Shelf prices change often.

How we compare: every figure comes from the guaranteed analysis and ingredient list of recipes we review, not from the brand's own claims. Starch is our estimate, since no manufacturer prints it. The written comparison is drafted from these figures, and every number in it is checked against them. Figures refreshed October 25, 2026.
