Feeding a Devon Rex well in Australia comes down to three decisions: wet-vs-dry split, portion control, and breed-specific risk management. The Devon Rex sits at small size with high energy — its calorie ceiling is 303 kcal/day, and its biggest food-related risks are Devon Rex myopathy (DNA test) and Hypertrophic cardiomyopathy. Here's what to feed, how much, and what to skip.

Daily portion for a Devon Rex
A small cat at 2.5–4.5 kg with high energy needs 195–303 kcal/day. Indoor, neutered, low-activity adults sit at the low end; intact or outdoor-access cats sit at the high end. The right split for most:
- One 85g wet pouch (Fancy Feast Classic or Advance Wet) — ~70 kcal — once daily, ideally morning or evening.
- Measured dry kibble for the remaining ~125–233 kcal. Most AU dry foods are 3800–4200 kcal/kg, so that's 31–58g of kibble daily.
- Fresh water available 24/7 — a moving fountain genuinely increases intake.
- Weight check monthly. Cats hide weight gain under fur. A bathroom-scale-yourself-then-with-cat is enough.

Devon Rex-specific watchouts
- Avoid grain-free legume-heavy diets — DCM/HCM linkage research is still active, default to grain-inclusive formulas.
Where to buy in Australia
Pet Circle and Petbarn carry every food on this list. Pet Circle is consistently cheapest on autoship + bulk; Petbarn wins on click-and-collect from 200+ stores. For parasite prevention specifically (which is part of the monthly cat budget even if not strictly "food"), VetSupply usually beats both.
Frequently asked questions
How much should a Devon Rex eat per day in Australia?
A typical Devon Rex (2.5–4.5 kg) needs around 195–303 kcal/day. That's roughly 3–4 ×85g wet pouches OR 0–1 dry-cup equivalents of an average kibble (~4000 kcal/kg). Indoor neutered cats sit at the low end of the range; outdoor or intact at the high end.
What food do most AU vets recommend for a Devon Rex?
In Australian vet clinics, Royal Canin and Hill's Science Diet are the most-recommended brands for adult cats — both have breed-aware or condition-specific lines suitable for Devon Rexs. Black Hawk and Advance are the strongest Australian-made alternatives.
Is grain-free food good for a Devon Rex?
Not necessarily. The FDA's 2018 grain-free DCM warning was for dogs, but recent feline research has flagged possible HCM linkage in cats fed legume-heavy grain-free diets long-term. Cats need taurine, methionine, arachidonic acid — not "no grain". For breeds with hereditary HCM risk (Maine Coon, Ragdoll), default to grain-inclusive formulas unless a vet specifically prescribes otherwise.
How much does feeding a Devon Rex cost per month?
Budget around $45 – $75 for a Devon Rex on a wet+dry mixed diet using mid-range AU brands (Royal Canin / Hill's / Advance / Black Hawk). Premium air-dried (Ziwi Peak, Prime100) doubles that; cheap supermarket-only diets cut it in half but with documented long-term cost in vet bills.
When should I switch a Devon Rex from kitten to adult food?
Most Devon Rexs switch at 12 months. Transition over 7–10 days by gradually mixing increasing proportions of adult food.
