Here are pet-food brands (Australian and international) that explicitly market to cat owners seeking “natural” diets — including grain‑free, high‑meat, raw, air‑dried or minimally processed options. I’ve noted what each brand emphasises and included sources showing their natural/biologically‑appropriate positioning or availability in Australia.

• Feline Natural — New Zealand maker of high‑meat freeze‑dried and wet recipes (grass‑fed, free‑range claims; marketed as whole‑food, natural cat nutrition). (myrainbowpets.com.au)
• Ivory Coat — Australian brand that promotes “Australian Natural Health” recipes, grain‑free formulas and “no artificial colours, flavours or preservatives.” (ivorycoat.com.au)
• Orijen / Acana (Champion/Orijen) — biologically appropriate, high‑animal‑protein, grain‑free diets that market as mimicking a cat’s natural prey diet; widely sold in Australia. (myrainbowpets.com.au)
• ZIWI Peak — New Zealand air‑dried and wet recipes emphasising 90%+ meat/organs/bone, minimal processing and no fillers or artificial additives. (ziwipetfood.com.au)
• Applaws — positions itself on “natural” and limited‑ingredient recipes (high meat content, grain‑free wet and dry lines, no artificial colours/flavours). (applaws.com.au)
• Instinct / Nature’s Variety — markets grain‑free, raw and high‑protein “Instinct” lines and raw options (Nature’s Variety is the parent company). (en.wikipedia.org)
• Ziwi, Feline Natural, Orijen and Applaws are commonly stocked by Australian pet retailers and specialist natural/RAW sellers (shows local availability). (adspet.com.au)
• FROZEN/RAW and Aussie raw brands (examples): Big Dog Pet Foods, Proudi, Organic Paws — market raw or minimally processed whole‑meat diets and are sold in Australian outlets. (theaustralian.com.au)
• Wellness, Applaws, Purina ONE Natural Blends, Natural Balance, Nulo, Taste of the Wild and similar mainstream “natural” / limited‑ingredient / grain‑free lines — many global brands now offer ranges pitched at owners wanting “natural” recipes (wet, dry, grain‑free or limited‑ingredient).

Notes and quick tips

• “Natural” is a marketing term with varying definitions — some brands mean “no artificial colours/flavours/preservatives,” others mean high meat content, and others promote minimally processed/raw or air‑dried approaches. Check ingredient lists and guaranteed analysis (protein/fat/carbs) for what matters to your cat.
• If you’re considering raw feeding (frozen, fresh or freeze/air‑dried), be mindful of food‑safety and nutritional completeness; many companies sell “complete” raw patties or offer feeding guides, but veterinary guidance is recommended for diet transitions or special health needs. (en.wikipedia.org)

If you’d like, I can:

• Filter this list to only Australian‑made brands, or only raw/freeze‑dried/air‑dried makers; or
• Pull ingredient examples and protein percentages for any 3 brands you pick so you can compare “natural” claims side‑by‑side.
