From “breed-specific” kibble to grain-free claims and glossy kitten food bags, the pet food industry is loaded with marketing buzzwords — not real biology.
This article debunks the biggest myths about feline nutrition and highlights the truths that matter most for raising a healthy cat, straight from a veterinarian’s perspective.
LIE #1: “Cats need grain-free food.”
The truth: Cats don’t need grains — but many “grain-free” foods just swap grains for peas, lentils, or potatoes, which are still carbs and still unnecessary.
High-starch “grain-free” diets are linked to obesity, gut issues, and even urinary tract disorders.
LIE #2: “Kitten food is specially formulated.”
The truth: Most “kitten food” is just higher-calorie kibble — often still full of fillers. You don’t need a kitten label — you need a food labeled for “all life stages” with high protein, high fat, and real meat.
Brands like Ziwi and Feline Natural are all-life-stage approved with no fluff.
LIE #3: “Dry food cleans your cat’s teeth.”
The truth: It doesn’t. In fact, many dental issues are caused or worsened by dry food diets.
- Most cats barely chew kibble — they swallow it whole
- Starch residue sticks to teeth and feeds the mouth bacteria
- Freeze-dried meat treats or raw bones are better dental tools
LIE #4: “Vet-recommended = healthiest”
The truth: Many vet-endorsed brands are backed by corporate partnerships and use marketing terms like “science-based” to cover up low meat content, high filler, and artificial additives.
A vet-written label isn’t a guarantee of quality — look at the ingredients.
Truths You Can Trust
Cats are obligate carnivores
- They need protein and fat from animal sources
- They do not need carbs — at all
Moisture matters
- Dry food is 10% water; raw prey is 70–75%
- Hydration supports kidneys, digestion, and urinary tract health
Simple, whole-ingredient diets are best
- Look for named proteins, organs, bone, and fat
- Short ingredient lists win — no mystery “meals” or “flavors”
Want to Feed What Actually Works?
- Ziwi Air-Dried Raw (NZ meat, organs, no fillers)
- Feline Natural Freeze-Dried or Canned (high moisture, clean meat)
- Raw (homemade or brands like Big Dog or Balanced Life — balanced with calcium & taurine)
Transition slowly using bone broth, raw goat milk, or freeze-dried toppers.
From Dr Duncan Houston
“Pet food marketing exists to sell bags — not to educate. If your cat’s food contains more starch than meat, it’s not species-appropriate. Meat, moisture, and simplicity are what matter.”
