No one likes to see their beloved cat unwell. Having a pet with health concerns, especially a chronic health condition, can be stressful and at times leave pet parents feeling completely helpless. A healthy, well-balanced diet is an important starting point for any cat, and feeding a diet designed to help prevent or support certain health conditions is something you can do every day.
Yes, diet can help manage the most common cat health conditions, including urinary problems, kidney disease, diabetes, sensitive stomachs, food allergies and hairballs. The right type of food depends on the condition and on your vet's advice, so check in before you change anything. If you're still working out the basics, start with our cat food guide.
What should I feed a cat with a sensitive stomach?
Cats with a sensitive stomach usually do best on a highly digestible diet with added fibre and pre and probiotics. Digestive issues are among the most common reasons cats see the vet, with 'on and off' bouts of mild diarrhoea, gas or vomiting that leave your cat downright miserable.
How your cat's digestive system works explains why tummies get upset. Not sure it's a food problem? Check the signs of digestive issues, and see how gut health and the microbiome fit in. Severe or ongoing signs can point to more complex issues like inflammatory bowel disease (IBD) or megacolon, so head to your vet.
Our best cat food for sensitive stomachs guide has our vet picks, and our probiotics for cats guide explains how digestive supplements can help.
What should I feed a cat with urinary problems?
Cats with urinary problems usually need a prescription urinary diet that controls and balances minerals and lowers urine pH to reduce crystal and stone formation. Urinating outside the litter tray is one of the most common complaints pet parents have, and for cats it is often a sign of an underlying medical condition, so get it checked first.
Our best urinary cat food guide covers the options, and Feline Lower Urinary Tract Disease (FLUTD) explains the condition itself. You can also read about urinary crystals and preventing urinary issues.
What should I feed a cat with kidney disease?
Cats with kidney disease usually do best on a kidney (renal) diet, which is lower in phosphorus and uses controlled levels of high quality protein to help support remaining kidney function. The right diet depends on how far along the disease is, so your vet needs to guide the choice.
See our best food for cats with kidney disease guide, and the full guides on kidney disease in cats and managing kidney disease.
What should I feed a diabetic cat?
Diabetic cats generally do best on a high protein, low carbohydrate diet, often wet food, fed consistently alongside the insulin your vet prescribes. Food and insulin work as a pair, so never change one without talking to your vet.
Start with diabetes in cats for signs, treatment and monitoring, and see our guide to the best food for cats with diabetes.
What should I feed a cat with food allergies?
True food allergies are less common than most people think, and they are confirmed with a strict diet trial, usually a novel protein or hydrolysed diet, run with your vet. Check out our guide to cats with sensitive, itchy skin, for other causes of itchy skin.
Read about food allergies in cats, our guide to novel protein diets, and what to feed for healthy skin and coat.
What food helps with hairballs?
Hairball control diets use extra fibre to help hair pass through the digestive tract, plus omega fatty acids for a healthy coat and less shedding. Frequent hairballs can point to skin, digestive or stress issues, so if your cat is bringing up hairballs more than once a week, be sure to see your vet first.

Can diet help with dental health and weight?
Yes, to a point. Dental diets use specially shaped and textured kibble that scrubs the tooth surface to reduce plaque, and weight management diets are lower in calories and higher in fibre so cats feel fuller for longer. Around 80% of cats over three have some degree of dental disease, and studies suggest about 32% of Australian cats are overweight or obese. Diet helps with these conditions, but it is not the whole answer, and best combined with other management strategies.
When do prescription diets make sense?
Prescription diets make sense when your cat has a diagnosed condition, such as urinary crystals, kidney disease or a severe digestive problem, and your vet wants better control and management than an everyday diet can give. In clinic, the most common pattern we see is a cat's food being changed several times before anyone has checked the underlying cause. A quick vet check first usually saves weeks of trial and error.
