Kitten Foods for Diarrhea: Growth Dry, Stew, and Sachet Stay Apart (2026)

The linked bag is Hill’s Science Diet Kitten Sensitive Stomach and Skin, salmon and brown rice, 3.5 lb. The US recipe page lists the same dry food in 6 lb and 3.5 lb. Ingredients begin with salmon, brown rice, chicken, chicken meal, and chicken fat, then pea protein and corn protein meal. Feeding tips say to mix increasing amounts of the new food with decreasing amounts of the old food over a 7-day period, and to keep fresh water available. The growth table is in cups and grams. At 1 lb, shown as 1 (0,5), a kitten under 4 months is 1/4 cup (30 g), and the older columns are blank. At the row printed 6 (2,7), under 4 months is 7/8 cup (110 g), 4 to 6 months is 3/4 cup (95 g), and 7 to 12 months and pregnancy is 5/8 cup (80 g). The rest of the rows stay on the Hill’s page. Do not fill a blank cell.

Calorie content is 4150 kcal/kg and 518 kcal per cup. The footnote says an 8 fl oz cup of this product weighs 4.4 oz. The nutrient table is dry matter: protein 37.7%, fat 24.8%, carbohydrate 27.6%, crude fiber 1.5%, calcium 1.34%, phosphorus 1.19%, taurine 0.45%. Dry matter is the food after water is removed. It is not the percentage in the cup. The page opened did not print an as-fed guaranteed analysis, so a retailer line near 33% protein, 4% fiber, or a DHA percentage stays off this card. Hill’s says the formula includes DHA for brain development and does not print a DHA percent here. The feeding-test sentence says animal feeding tests using AAFCO procedures substantiate that it provides complete and balanced nutrition for growing kittens and gestating or lactating adult female cats. On the page opened, the product name is missing between “that” and “provides.” Recommended for kittens from weaning until 1 year and for pregnant or nursing cats, including those with a sensitive stomach or skin. Not recommended for adult cats, cats 7 and older, or obese or obese-prone cats. Highly digestible, prebiotic fiber, and the antioxidant lines are Hill’s sentences. They are not a result from this page.

The linked stew is Hill’s Science Diet Kitten Sensitive Stomach and Skin, salmon and vegetable, in 2.8 oz cans. A shop case is 24 cans. Ingredients begin with chicken broth, salmon, carrots, turkey, and pork liver, then spinach, rice starch, and rice. Salmon is not first. The name does not make this a salmon-only can. Feeding tips again say a 7-day mix and fresh water. The growth table is in 2.8 oz (79 g) cans. At 1 lb, shown as 1 (0,5), a kitten under 4 months is 2 1/8 cans, and the older columns are blank. At the row printed 6 (2,7), under 4 months is 8 1/4 cans, 4 to 6 months is 6 3/4 cans, and 7 to 12 months is 5 1/2 cans. That third column is growth only. It is not a pregnancy column. A generated line of about 1 can per 3.5 lb does not match this table.

Calorie content is 687 kcal/kg and 54 kcal per can. Dry matter is protein 36.4%, fat 23.4%, carbohydrate 30%, crude fiber 0.7%, and taurine 0.39%. Animal feeding tests using AAFCO procedures substantiate that this named stew provides complete and balanced nutrition for growing kittens. Recommended for kittens up to 1 year. Not recommended for adult cats, cats 7 and older, obese or obese-prone cats, or pregnant and lactating cats. The dry bag on this page includes pregnant and nursing cats. This stew does not. A shop card that lists the pet age as kitten, pregnant, or nursing disagrees with the recipe page. A shop line that calls the stew grain-free also disagrees with rice starch and rice in the ingredient list. Do not repair either slip. Prebiotic fiber and the antioxidant lines are Hill’s sentences. A prescription digestive kitten can is a different product and is not linked here.

The linked bag is Purina Pro Plan Kitten Sensitive Skin and Stomach, salmon and rice, 3.5 lb. The label code on the US deck is A478524, manufactured by Nestle Purina PetCare Company, St. Louis, MO 63164 USA. Ingredients begin with salmon, rice, chicken by-product meal, and corn protein meal. Later lines include dried chicory root and fish oil. The deck does not start with oatmeal. A shopping bullet that describes an adult salmon food with rice and oatmeal is a different formula pasted onto this listing. Guaranteed analysis: crude protein 42.0% minimum, crude fat 19.0% minimum, crude fiber 2.5% maximum, moisture 12.0% maximum, linoleic acid 1.9% minimum, DHA 0.02% minimum, calcium 1.0% minimum, phosphorus 0.8% minimum, vitamin A 10,000 IU/kg minimum, vitamin E 400 IU/kg minimum, taurine 0.18% minimum. Omega-6 fatty acids are 2.0% minimum and are marked not recognized as an essential nutrient by the AAFCO Cat Food Nutrient Profiles.

The formula is formulated to meet AAFCO Cat Food Nutrient Profiles for growth of kittens and gestation or lactation. That is a formulation statement, not the feeding-test sentence on the Hill’s pages. Calorie content is 3966 kcal/kg and 583 kcal per cup. The measuring note says a standard 8 oz cup holds about 147 g of this food. Do not use Hill’s 4.4 oz cup, or an adult sensitive bag near 492 kcal per cup, on this row. The youngest feeding row is 4 to 12 weeks and 1 to 3 lb: 1/4 to 1/3 cup, 37 to 49 g. At 12 to 24 weeks and 3 to 5 lb the deck says 1/3 to 1/2 cup, 49 to 74 g. A Canada table that prints 12 to 14 weeks for that second row stays in Canada. Kittens may nibble solid food at 3 to 4 weeks. If water is added, use no more than one part warm, not hot, liquid to three parts food. The switch is 7 to 10 days, a little less of the previous food each day. For reproduction, the deck says not to add supplemental vitamins or minerals, to feed the pregnant cat for body condition, and that intake by the fourth week of lactation can be 2 to 3 times the intake before breeding. Those sentences are Purina’s. They are not a diarrhea result.

Purina’s US page for FortiFlora describes a probiotic powder for the dietary management of diarrhea in kittens and adult cats. Active ingredients per 1 g sachet are Enterococcus faecium SF68 at 1×10^8 CFU and taurine 5 mg. Inactive ingredients are liver flavor and yeast. Directions say for use in cats only, and one packet daily or as a veterinarian directs. The product description says the powder is sprinkled on the regular food. It does not replace that food, and it does not print a growth statement. A shop extract adds code A-9302, says to stop the product if the condition worsens or does not improve, says safe use in pregnant animals or animals intended for breeding has not been proven, and recommends a veterinary examination first.

A Canada card near 3.7 kcal per sachet, a UK sheet with a higher CFU floor, a diarrhea kit whose sachet extract names Enterococcus lactis, and a 1.5 g synbiotic with 7.5 mg of taurine stay off this card. Direct opening of the US product page was blocked on the day of this rebuild. The search extracts of that URL and of the shop page agreed on faecium, 1×10^8 CFU, 5 mg of taurine, liver flavor, and yeast. Cornell’s parasite page still matters: kittens can take in roundworm larvae through the queen’s milk, and Isospora can cause mucousy diarrhea in kittens. A sachet is not that workup.
