Wet vs Dry Cat Food in Australia — the actual answer

Dry kibble is convenient. Wet food is better for hydration. The right split depends on your cat's age, breed, and how much effort you'll actually commit to.
The wet-vs-dry debate is one of those pet-care questions where both sides overstate their case. Here's what the current veterinary research actually supports, and what that means for an average Australian cat.
The case for wet food
Cats are obligate carnivores descended from desert ancestors. They evolved to get most of their water from prey — not from a water bowl. Domesticated cats on a dry-only diet rarely drink enough water to compensate. The knock-on effects, confirmed by longitudinal studies at Cornell and the University of Sydney:
- Higher incidence of feline lower urinary tract disease (FLUTD)
- Higher rates of chronic kidney disease in senior cats
- Higher urine concentration, which predisposes to crystal and stone formation
Wet food is 75–80% moisture versus 8–10% in dry kibble. Cats eating wet food consume 3–4× more water in total.
The case for dry food
- Cheaper per kilocalorie — a bag of Black Hawk at $14.50/kg is ~$3.50 per 1000 kcal; wet food is $11–30 per 1000 kcal.
- Dental benefit — mild abrasion from kibble reduces (but doesn't eliminate) plaque buildup. Effect is real but smaller than marketing implies.
- Storage and convenience — kibble keeps for weeks; wet food needs refrigeration after opening and can't be left out.
- Free-feeding friendly — many cats do better with kibble available all day rather than discrete wet meals.
The right split for most cats
Most Australian vets now recommend a combined diet: at least one wet meal per day (pouch or half-can, 70–100g) plus measured dry kibble for the rest of the day's kilocalorie need.
For a 4.5kg indoor neutered cat: - Total kcal needs: ~165 kcal/day - One 85g pouch Fancy Feast Classic: ~70 kcal - Remaining dry kibble (Black Hawk at 4000 kcal/kg): ~24g
Expected cost: $55–85/month. Our cat food cost calculator lets you run this for any cat.
When to go wet-only
- Cats prone to FLUTD — male cats, breeds with known urinary issues (Persian, Maine Coon)
- Senior cats with early chronic kidney disease — moisture matters enormously at this stage
- Cats who won't drink enough — if you weigh the water bowl and it barely moves, switch more of the diet to wet
When dry-only is (grudgingly) acceptable
- Cats with specific dental conditions where wet food worsens plaque
- Multi-cat households with a "food bully" — kibble can be free-fed while wet is supervised per cat
- Extreme budget constraints where the alternative is cheap supermarket wet food (which is nutritionally worse than mid-range dry)
The wrong answer here is "whatever's easiest and cheapest". Dry-only is not a neutral default — it has documented downstream costs in vet bills over a 15-year life. Budget the wet food in from day one.
