Here are cat food brands that are commonly recommended by veterinarians in Australia, with sources you can check:

• Royal Canin — widely promoted as a “veterinarian‑recommended” brand in Australia (regular retail and veterinary/prescription lines). (royalcanin.com)

• Hill’s (Science Diet and Prescription Diet) — frequently recommended by vets for both everyday nutrition and condition‑specific therapeutic diets. (hillspet.com.au)

• Purina Pro Plan / Purina Veterinary Diets — Purina’s Pro Plan and veterinary diet ranges are commonly used/recommended by Australian veterinary clinics. (Purina.com.au)

• Advance (Australian brand) — an Australian‑made, science‑backed range that is commonly stocked and recommended by vets and vet retailers in Australia. (petfood.advancepet.com.au)

• Orijen / Acana (Champion Petfoods) — premium “biologically appropriate” brands often recommended by vets/nutritionists for owners seeking high‑protein premium diets (availability and recommendations can vary). (australiancatlover.com)

Notes veterinarians commonly make

• Many vets recommend specific veterinary prescription diets (Hill’s Prescription Diet, Royal Canin Veterinary Diet, Purina Veterinary Diets) for medical conditions such as kidney disease, urinary problems, obesity or digestive issues — these require veterinary assessment and follow‑up. (hillspet.com.au)
• “Vet‑recommended” doesn’t always mean one brand is best for every cat. Choice depends on your cat’s age, health status, allergies, weight and owner budget; vets often prioritise clinical evidence and an individual assessment. (royalcanin.com)

If you want, I can:

• Suggest suitable formulas for a kitten, adult, senior or a cat with a specific health issue (eg urinary disease, kidney disease, weight management) and cite the relevant prescription/clinical information.
• Find vet clinic or Australian veterinary guidance comparing these brands or local availability/prices.
