How Do I Choose Cat Food
Medically Reviewed by Dr. Marcus Thorne, BVSc, Veterinary Behaviorist

Understanding Your Cat's Nutritional Needs
Cats are obligate carnivores, meaning they require nutrients found primarily in animal tissue. Unlike dogs or humans, cats have specific dietary requirements that cannot be met by plant-based foods alone. When choosing cat food, understanding these unique needs is the foundation for making an informed decision. Your cat’s health, energy, coat quality, and longevity all depend on the food you provide.
Types of Cat Food
Dry Food (Kibble)
Characteristics:
-
Lower in moisture content (typically 6-10%)
-
Long shelf life once opened
-
More convenient for free-feeding
-
Generally more affordable per serving
-
Can help with dental health through crunching action
Considerations:
-
May contribute to dehydration if your cat doesn’t drink enough water
-
Some formulas may contain more carbohydrates than ideal
-
Quality varies significantly between brands
Wet Food (Canned)
Characteristics:
-
Higher moisture content (typically 75-85%)
-
More palatable for many cats
-
Easier to eat for cats with dental issues
-
Can help with hydration
-
Often has stronger aroma
Considerations:
-
More expensive than dry food
-
Shorter shelf life once opened
-
Requires refrigeration after opening
-
Some cans may contain bisphenol A (BPA) in lining
Semi-Moist Food
Characteristics:
-
Moisture content between dry and wet food
-
Convenient portioned packaging
-
Often marketed as close to natural prey moisture
Considerations:
-
Less commonly available
-
May contain more preservatives
-
Generally not considered the best nutritional option
Raw and Homemade Diets
Characteristics:
-
Raw diets attempt to replicate natural feline prey
-
Homemade diets allow control over ingredients
-
Can include raw or cooked meat, organs, and bones
Considerations:
-
Must be properly balanced to meet nutritional needs
-
Risk of bacterial contamination with raw foods
-
Requires significant research and potentially veterinary nutritionist consultation
-
Bones can pose choking or injury risks
Reading Cat Food Labels
Understanding the label is crucial for making informed choices:
Key Label Elements
1. AAFCO Statement: Look for “complete and balanced” with a life stage designation (kitten, adult, or senior). This indicates the food meets minimum nutritional standards.
2. Ingredient List: Ingredients are listed by weight before processing. Look for:
-
Meat or meat meal as the first ingredient
-
Named protein sources (chicken, salmon, beef) rather than generic “meat”
-
Limited use of fillers and by-products
3. Guaranteed Analysis: Shows minimum/maximum levels of key nutrients:
-
Protein (higher is generally better for cats)
-
Fat (essential for energy and coat health)
-
Fiber (for digestive health)
-
Moisture (higher in wet foods)
4. Nutritional Adequacy Statement: Confirms the food is formulated for a specific life stage or all life stages.
Ingredients to Understand
Protein Sources:
-
Named meat (chicken, turkey, fish)
-
Meat meals (concentrated protein)
-
By-products (nutritionally valid but quality varies)
Fillers and Carbohydrates:
-
Corn, wheat, rice, potatoes
-
Used as energy sources and to hold kibble together
-
Cats have limited carbohydrate requirements
Additives:
-
Preservatives (natural vs. artificial)
-
Taurine (essential amino acid for cats)
-
Vitamins and minerals
-
Taurine must be added—cats cannot produce it naturally
Matching Food to Life Stage
Kitten Food (Birth to 12 Months)
-
Higher protein and fat for growth
-
DHA for brain and eye development
-
Smaller kibble size
-
More calories per serving
Adult Cat Food (1-7 Years)
-
Maintenance nutrition for adult needs
-
Balanced protein and fat levels
-
Should maintain healthy weight
Senior Cat Food (7+ Years)
-
May have adjusted protein levels
-
Joint support ingredients
-
Lower calorie options for less active cats
-
Added antioxidants for aging immune systems
Special Dietary Considerations
Food Allergies and Sensitivities
Some cats may develop sensitivities to certain ingredients:
-
Common allergens include chicken, beef, fish, dairy, corn, wheat, and soy
-
Symptoms may include skin issues, digestive upset, or excessive grooming
-
Limited ingredient or hypoallergenic diets may help
Weight Management
For cats prone to weight gain:
-
Look for lower-calorie formulas
-
High protein helps maintain muscle while reducing fat
-
Fiber content can help cats feel full
-
Measured portions are essential
Urinary Health
Some cats are prone to urinary issues:
-
Diets designed for urinary health have adjusted mineral levels
-
Increased moisture from wet food can help
-
pH management in some formulas
Evaluating Food Quality
Quality Indicators
Good Signs:
-
Named protein sources at the top of the ingredient list
-
Clear nutritional adequacy statements
-
Company has veterinary nutritionists on staff
-
Conducted feeding trials
-
Transparent about sourcing
Red Flags:
-
Vague ingredient descriptions (“meat by-products”)
-
Excessive fillers as primary ingredients
-
No nutritional adequacy statement
-
Unverified claims or miracle cures
-
No information about quality control
Brand Reputation
Research Brands:
-
Look for companies with research and development
-
Check for veterinary involvement
-
Read reviews from other cat owners
-
Consider longevity of the company
-
Be cautious of heavily marketed “miracle” foods
Price Considerations
Budget Tiers
** economy:** Often lower-quality ingredients, more fillers, less meat-based protein
Mid-range: Generally good nutritional balance, named ingredients, reasonable quality
Premium: Higher meat content, better ingredient sourcing, more research
Note: Higher price doesn’t always mean better, but very cheap food often uses lower-quality ingredients. Balance cost with quality considerations.
Wet vs. Dry: Making the Choice
Arguments for Wet Food
-
Higher moisture supports kidney and urinary health
-
More palatable for picky eaters
-
Lower carbohydrates
-
Better for hydration
Arguments for Dry Food
-
More convenient
-
Better for dental health
-
More economical
-
Can be left out longer
Combination Approach
Many veterinarians recommend feeding both wet and dry food, giving cats the benefits of each while providing variety.
Making the Switch
If changing foods:
-
Transition gradually over 7-10 days
-
Mix new food with current food
-
Slowly increase the proportion of new food
-
Watch for digestive upset
-
Monitor appetite and acceptance
Quick changes can cause digestive upset. Some cats may also refuse new foods if the transition is too abrupt.
Common Mistakes to Avoid
Don’t:
-
Choose food based solely on price
-
Assume “natural” or “organic” means nutritionally complete
-
Feed dog food (it’s inappropriate for cats)
-
Rely on marketing claims without checking facts
-
Switch foods too frequently
-
Free-feed without monitoring weight
-
Assume your cat needs variety (some do, some don’t)
Questions to Ask Yourself
Before choosing cat food:
-
Does this food meet AAFCO standards?
-
Is the protein source appropriate?
-
Does it match my cat’s life stage?
-
Does my cat have any health conditions to consider?
-
Can I afford to feed this food consistently?
-
What do veterinary professionals recommend?
-
Is this brand reputable?
If your cat shows signs of food allergies, digestive problems, weight changes, coat deterioration, or any health concerns related to diet, please consult a veterinarian for proper evaluation and guidance.
