WikiCompare live prices on cat food across Amazon, eBay, AliExpress, and partner merchants. Cats are obligate carnivores — they need meat-based protein, not the grain-heavy formulas of cheap brands. Vet-recommended: Royal Canin, Hill's Science Diet, Purina Pro Plan. Wet food daily is important for hydration (cats have poor thirst drive — kidney disease is the #1 senior cat killer). Dry food as backup or for puzzle feeders. For weight management, automatic portion-control feeders (PetSafe Smart Feed) prevent overfeeding. Avoid: budget grocery-store brands (Friskies, Meow Mix — high carb, low quality protein), grain-free dry food, raw diets without veterinary supervision.

Frequently asked questions about cat food
What's the best cat food brand?
Royal Canin, Hill's Science Diet, Purina Pro Plan — all veterinarian-recommended with feeding trials. Specifically for cats: high-protein, taurine-fortified, low-carb. Wet food daily is important (cats have poor thirst drive — kidney disease #1 senior cat killer). Skip grocery brands (Friskies, Meow Mix) — high carb, low quality.
Wet vs dry cat food?
Both — wet food daily (1-2 cans) for hydration + protein. Dry food as supplemental snack or puzzle feeder content. Wet food is essential for senior cats and any cat with chronic kidney issues (most older cats). Dry-food-only diets cause urinary tract issues. Avoid free-feeding dry food — leads to obesity in most indoor cats.
Where to buy cat food cheap?
Chewy with Auto-Ship (5-10% off recurring + free shipping over $49). Costco for Kirkland Signature (high quality at half the price of premium brands). Amazon for established brands (Subscribe & Save 15%). Avoid: bulk Friskies (lowest quality), grain-free trendy brands without research backing.
How much should I feed my cat?
Average adult cat needs 250-350 calories daily depending on weight + activity. Follow food packaging guidelines as starting point. Indoor adult cats often need less than the label suggests. Watch body condition: ribs felt easily (not seen) = healthy weight. Obesity is the #1 cat health issue — adjust portions if your cat is overweight.
