Table 1. Criteria used for scoring clinical signs and symptoms, including fecal consistency, overall health, hydration, and appetite.

Score	Fecal Consistency	Health Status	Hydration Status	Appetite
1	Normal feces; feces retain form. The feces may be pasty but do not flow across a surface.	Normal: alert, hungry, interacts with caregivers	Normal; skin tents <1 second; moist mucus membranes	Normal: interacts with caregivers and eats greedily; eats 75–100% of meal
2	Mild-to-moderate diarrhea: unformed feces, flows down a surface, while leaving some residual	Mildly depressed: some loss of interest in feeding, equivocal hydration status	Mildly dehydrated: skin tents 1–4 seconds; normal mucus membranes	Mild inappetence: some loss of interest but eats 25–75% of meal
3	Severe diarrhea: part or all of feces is very watery; flows down a surface, while leaving no residual	Severely depressed: lethargic, must be coaxed to get up, anorexia, requires supportive treatment	Severely Dehydrated: skin won’t flatten when tented, eyes sunken, dry mucous membranes	Anorexic: loss of interest in feeding; eats 0–25% of meal
