Quick answer: Which cat food is best? When purchasing high-quality cat food, pay attention to five key points—(1) meet the complete nutritional standards of AAFCO or FEDIAF; (2) the ingredient list must be a well-known meat; (3) protein should not be less than 30% (cats need more than dogs); and (4) must contain sufficient taurine(Taurine, an essential amino acid for cats), (5) Purchase genuine products through authorized channels. Recommended brands in Hong Kong for 2026 include Orijen (40% protein), Ziwi Peak (96% meat), Wellness CORE, Fromm, and Stella & Chewy’s.
Key Summary TL; DR
- Protein is king: Cats are obligate carnivores. AAFCO requires adult cat food to have ≥26% protein, but high-quality cat food usually reaches 35-45%.
- Taurine is essential: Cats cannot synthesize enough taurine on their own, and deficiency can lead to heart disease and retinal degeneration. AAFCO requires dry food ≥ 0.1%.
- Check the ingredients: The first three should be named meats (such as ‘boneless chicken’), avoiding ‘meat by-products’ and artificial additives
- Top 10 Brand Recommendations: Orijen, Acana, Wellness CORE, Go! Solutions、Fromm、Oven-Baked Tradition、Ziwi Peak、K9 Natural、Stella & Chewy’s、AATU
- Hong Kong climate: Average annual humidity of 78%. Dry food should be eaten within 4-6 weeks after opening and stored in sealed containers
Cats are obligate carnivores, and their nutritional needs are completely different from dogs’—they require higher protein and must obtain essential cat-specific nutrients like taurine and arachidonic acid from their food. This means cat food recommendations cannot simply follow the logic of choosing dog food.
According to Hong Kong statistics, the market size of the pet industry has reached HKD 6.2 billion, with the number of cats kept continuously rising in recent years. Faced with hundreds of cat food options on the market, many cat owners feel that “which cat food is best” is a headache.
This guide was written by the BC Pets Pet Supplies Center team (which has been serving Hong Kong pet owners since 2009). Based on AAFCO nutritional standards and years of experience serving local cat owners, it has compiled a cat food selection framework that best suits Hong Kong’s environment.
Key Point 1: Understand AAFCO cat food nutrition standards
AAFCO (Association of American Feed Control Officials) has established two sets of nutritional standards for cat food: Growth (kittens/pregnancy) and Maintenance (adult cats). Here are the key nutritional indicators for cat food:
| Nutritional indicators | Minimum adult cat requirements | Minimum requirements for kittens | Premium cat food range |
|---|---|---|---|
| Crude protein | ≥26% | ≥30% | 35-45% |
| Crude fat | ≥9% | ≥9% | 12-20% |
| taurine (dry food) | ≥0.1% | ≥0.1% | 0.15-0.3% |
| taurine (canned food) | ≥0.2% | ≥0.2% | 0.2-0.4% |
| Coarse fiber | ≤5% | ≤5% | 2-4% |
| Moisture (dry food) | ≤10% | ≤10% | 6-10% |
*Data source: AAFCO official nutrition standards. The European standard is based on FEDIAF.
Key differences: The biggest differences between cat food and dog food are—(1) cats need higher protein (26% vs. 18% for dogs); (2) Cats must consume taurine (dogs can synthesize it themselves); (3) Cats need arachidonic acid, which can only be obtained from animal fats. This is why cats must never be fed dog food.
Key Point 2: Read the ingredient list carefully—protein and taurine
Cat food ingredient list is arranged by raw material weight from highest to lowest. As exclusive carnivores, the ideal diet for cats should center on animal protein as the absolute centerpiece.
Quick reference table for ingredient tables
| Ingredient categories | Premium ✓ | Avoid ✗ |
|---|---|---|
| Protein sources | Boneless chicken, fresh salmon, chicken meal, turkey | Meat by-products, poultry by-products, “meat” (unnamed) |
| Fat sources | Chicken fat, salmon oil (containing Omega-3), flaxseed oil | “Animal fat” (source not specified) |
| Essential nutrients | Taurine, arachidonic acid, vitamin A (pre-formulated) | It lacks taurine labeling and only contains plant-based vitamin A precursors |
| Carbohydrates | Sweet potato, peas, brown rice (appropriate amount) | Corn gluten powder, soy flour (high proportion filling) |
| Preservatives | Natural vitamin E (Mixed Tocopherols), rosemary extract | BHA, BHT, Ethoxyquin (chemical preservatives) |
Cat owners must know: Cats are different from dogs and have limited ability to digest carbohydrates. Carbohydrates in the diet of wild felines are less than 5%. When choosing cat food, the lower the carbohydrate ratio, the better—high-quality cat food is usually kept at 20-30% (calculation method: 100% minus protein%, fat, fiber, ash, and water).
Key Point 3: Choose the appropriate formula according to age
Cats have significant differences in nutritional needs at different life stages. Choosing the right formula is the foundation for ensuring your cat’s healthy growth.
Kittens (0-12 months)
- Protein ≥30%
- Fat ≥9% (recommended 15%+)
- Contains DHA to support brain development
- High calcium supports bone growth
- Feed 3-4 times daily
Adult cat (1-7 years)
- Protein ≥26%
- Fat 9-15%
- Balances vitamins and minerals
- Control calories according to body weight
- Feed twice daily
Old Cat (7 years and above)
- Protein ≥30% (maintains muscle)
- Easy-to-digest formula
- Contains glucosamine (joint)
- Urinary tract health formula
- Feed 2-3 times a day
Pro advice: Older cats actually need more protein than adult cats—because their protein digestion and absorption rate decreases, requiring more protein to maintain muscle mass. According to veterinary nutrition research, the protein content in senior cat food should be 30-45%. The previous recommendation that “older cats should be low in protein” has been rejected by most veterinary nutritionists (unless kidney disease requires protein restriction).
Key Point 4: Dry Food vs. Wet Food—Which Is the Best Choice?
Both dry and wet foods have their pros and cons, and many veterinarians recommend mixing feedings to get the benefits of both:
| Comparison items | Dry Food | Wet Food / Canned Food |
|---|---|---|
| Moisture content | About 6-10% | About 75-80% |
| Protein density | Higher (dry matter calculation) | The actual protein ratio appears lower due to the high water content |
| Storage convenience | Convenient and has a longer shelf life | After opening, refrigerate and consume within 2 days |
| Healthy teeth | Chewing helps reduce tartar | It doesn’t really help with dental cleaning |
| Hydration | Make sure your cat drinks enough water | Naturally replenishes fluids and reduces urinary tract risks |
| Suitable for: | Healthy adult cats and multi-cat households | Cats with low water intake, older cats, and those with urinary tract problems |
| Daily cost | Lower | Higher (can be combined with dry food to control costs) |
Mixed feeding recommendation: Dry food as the main food (about 70-80% calories), paired with one wet meal per day (main food cans, i.e., canned foods labeled as AAFCO Complete and Balanced, not complementary food cans or snack cans). This not only ensures balanced nutrition but also increases water intake. Pay attention to controlling total calories—generally, a 4-5kg adult cat needs about 200-250 kcal per day.
Key Point 5: Storage tips under Hong Kong’s climate
Hong Kong’s average annual relative humidity reaches 78% (according to the Hong Kong Observatory), and summers often exceed 90%. Cats are extremely sensitive to food freshness; spoiled cat food will not only be refused but may also cause digestive problems.
Five key storage points: (1) Keep the original packaging—place the entire original packaging into a sealed container (the original bag has an anti-oxidation coating). (2) Store in a cool place—avoid direct sunlight and near stoves. (3) Finish within 4-6 weeks after opening—after this period, nutrient loss accelerates. (4) Refrigerate wet food after opening — eat within 2 days, seal the remaining portion with a plastic lid and store it in the refrigerator. (5) Regular inspections—if you notice any odors, clumps, or discoloration, discard them immediately.
Purchase advice: Hong Kong cat owners can consider purchasing smaller packages (such as 1.8kg/2.7kg) to ensure they are consumed within the best taste period. For single-cat families, it’s especially recommended to choose small packages. Although the price per kilogram is slightly higher, it ensures your cat gets fresh food at every meal.

Frequently Asked Questions (FAQ).
Q: Which cat food is best? What recommendations are there for 2026?
Recommended quality natural cat food brands for 2026 include: Orijen (40% protein, 90% animal ingredients), Ziwi Peak (96% meat, air-dried), Acana (75% animal origin), Wellness CORE (grain-free high protein), and Fromm (family-run for 120 years, stable formula). When purchasing, pay attention to AAFCO certification, the ingredient list should be named meat, protein content should not be less than 30%, and sufficient taurine content.
Q: How should I read the cat food ingredient list?
Cat food ingredient list is arranged by weight from highest to lowest. The top three high-quality cat foods should be named animal proteins (such as ‘boneless chicken’ and ‘fresh salmon’), and avoid choosing products that prioritize corn, wheat, or ‘meat by-products.’ Key nutritional indicators: crude protein should be at least 30% (higher for kittens), crude fat should be 9-20%, and taurine content should not be less than 0.1%. Avoid cat food containing BHA, BHT artificial preservatives, and artificial coloring.
Q: What food should kittens, adult cats, and senior cats eat?
Kittens (0-12 months) need formulas high in protein (over 30%), high in fat, high in calcium, and containing DHA to support rapid growth; For adult cats (ages 1-7), choose a balanced formula with at least 26% protein, and pay attention to controlling calories to avoid obesity; For senior cats (7 years and above), it is recommended to choose formulas that are easy to digest and contain joint health ingredients (glucosamine) and urinary tract health. Some brands, such as Orijen and Acana, offer the “All Life Stages” formula.
Q: Does cat food have to contain taurine?
Yes. Taurine is an essential amino acid for cats. Cats cannot synthesize enough taurine on their own and must obtain it from food. AAFCO standards require taurine content in dry food to be no less than 0.1%, and canned food no less than 0.2%. Long-term taurine deficiency can lead to dilated cardiomyopathy (DCM) and central retinal degeneration, which in severe cases can lead to blindness and heart failure. All high-quality cat food formulas ensure sufficient taurine is added.
Q: How should I choose between dry and wet food? Can I mix feeding them?
Dry food is easy to store and helps with dental cleaning, but has low moisture content (about 10%); Wet food is high in moisture content (about 75-80%), which helps cats get water and reduces the risk of urinary tract diseases. Many veterinarians and nutritionists recommend mixed feeding—mainly dry food, paired daily with an appropriate amount of wet food (main food jars rather than supplementary food cans), which ensures balanced nutrition and increases water intake. When mixing foods, be sure to control total calories to avoid becoming overweight.
Q: How should cat food be stored in Hong Kong’s humid weather?
Hong Kong’s average annual relative humidity reaches 78%. After opening dry food, it is recommended: (1) Place the original packaging in a sealed container (do not pour it out, as the original bag has an anti-oxidation coating); (2) Store in a cool, dry place, avoiding direct sunlight; (3) Consume within 4-6 weeks after opening; (4) If using vacuum-sealed bags, the period can be extended by 1-2 weeks. If you notice any abnormal smell, clumping, or discoloration of the grain, discard it immediately. Cats are very sensitive to food freshness; spoiled food may be refused or cause digestive issues.
Q: Is grain-free cat food good?
Grain-free cat food uses sweet potatoes, peas, and other grains as alternative carbohydrate sources, usually with higher protein content. For cats allergic to grains or sensitive digestion, grain-free formulas are a good choice. But not all cats need grain-free food—healthy, allergy-free cats eat formulas containing high-quality grains (such as brown rice and oats) in a balanced diet. Notably, the U.S. FDA investigated a potential link between grain-free pet food and heart disease (DCM), but as of 2024, no causal relationship was confirmed, and the investigation has been terminated. When choosing, you should consider the individual needs of your cat.

Summary
Core principles for choosing cat food: protein is king, taurine is essential, and ingredients must be transparent. Remember the three most important checkpoints: packaging must be AAFCO/FEDIAF certified, the ingredient list must have nominal animal protein at the top, protein content must be at least 30%, and taurine is included. Combined with proper storage and gradual food transition, you can provide your pet with a safe and balanced diet.
