Hill's Science Diet
Best for sensitive stomachs · $$$$
A safe, vet-backed choice for sensitive stomachs and clinical needs, but you pay a premium for the science, not the ingredients.
Fewer ingredients means fewer potential triggers. Look for a short, clear list — ideally one or two protein sources, a carbohydrate and essential nutrients only.
Identifying a protein your cat tolerates is easier when the recipe uses just one animal protein. Useful for cats that react to common proteins like chicken.
Products labelled 'sensitive' or 'digestive care' use protein and carbohydrate sources chosen for high digestibility, reducing the digestive burden on a sensitive gut.
Artificial colours, flavours and preservatives are unnecessary and may contribute to gut irritation. Look for 'no artificial additives' on pack.
For cats with confirmed sensitivities or allergies, a vet-formulated sensitive or hypoallergenic diet is more reliable than a general 'natural' claim.
Frequent vomiting, loose stools or skin irritation can have many causes. A vet assessment before switching food ensures you're treating the right problem.
Selected for limited-ingredient formulation, single-protein options, vet recommendation and Australian availability.
Hill's Science Diet Sensitive Stomach & Skin is one of the most widely vet-recommended formulas for digestive sensitivity in Australia. The recipe uses highly digestible ingredients, prebiotic fibre and omega-6 fatty acids for skin and coat. If your vet recommends a therapeutic diet, Hill's z/d (prescription) is the gold standard for confirmed food allergies.
Royal Canin Sensitive Digestion uses a tailored blend of highly digestible proteins and precise fibre levels to reduce stool volume and odour — a reliable clinical choice. For cats with confirmed food protein allergies, Royal Canin Hypoallergenic (prescription) uses hydrolysed protein to minimise immune response.
ZIWI Peak's single-region recipes use just one animal protein source per variant, making it straightforward to isolate a protein that your cat tolerates well. The short, natural ingredient list removes common irritants (grains, additives, artificial preservatives) that can trigger sensitive stomachs.
Applaws is built around a short, clean ingredient list with high named-meat content — no artificial additives, no unnecessary fillers. The limited-ingredient wet range is worth trying for cats that react to complex recipes; just ensure you choose a 'complete' product if it will be the sole diet.
Advance Sensitive offers an Australian-made, vet-recommended formula for digestive and skin sensitivity at a sensible everyday price. Widely stocked and easier to access than prescription diets, it's a practical first step before moving to therapeutic options.

Common signs include frequent vomiting (beyond occasional hairballs), loose or soft stools, excessive flatulence, a dull coat, and skin irritation. Occasional vomiting is normal for cats, but if it's frequent or accompanied by weight loss or lethargy, see your vet — these symptoms can indicate a range of conditions beyond simple dietary sensitivity.
Common triggers include artificial colours, flavours and preservatives; grain fillers like corn and wheat gluten; unnamed meat by-products; and high-fat recipes. Some cats react to specific proteins (chicken is the most common allergen). A limited-ingredient or single-protein food makes it easier to identify the trigger.
If your vet suspects a food allergy rather than general sensitivity, they may recommend a hydrolysed protein or novel-protein elimination diet — a strict 6–12-week process feeding only one protein source your cat has not had before. This must be done under veterinary guidance to be effective.
Not necessarily. Grains are only a problem for cats with a specific intolerance, and most sensitive stomachs react to the protein source rather than grain. That said, grain-free recipes often have simpler ingredient lists and fewer additives, which can benefit some cats. Focus on the total ingredient quality rather than grain-free as a proxy.
No. PetReviews is an independent comparison resource, not veterinary advice. If your cat has persistent digestive symptoms, please see your vet before trying a new diet — symptoms can signal underlying conditions that require diagnosis and treatment.
