a–c Within a row, means without a common superscript differ (p < 0.05). 1 SEM: Standard error of the mean. Means were based on 12 cat observations per diet. 2 Scores based on the following scale: 1 = watery, liquid that can be poured; 2 = unformed stool; 3 = soft, moist, formed stool; 4 = dry, well-formed stool; 5 = dry, hard pellets.
