Feeding your cat properly can feel overwhelming with so many food choices and opinions, but understanding the basics of feline nutrition makes it simple. Cats are obligate carnivores, meaning they need animal-based proteins and fats to stay healthy. With the right knowledge about protein, hydration, and portion control, you can help your cat live a longer, healthier life.
Understanding Your Cat’s Nutritional Needs
Cats aren’t small dogs—their metabolism and nutrient requirements are entirely different. As obligate carnivores, cats depend on nutrients found only in meat.
Key Nutrients Cats Need
- High-quality animal protein (≥26% for adults, ≥30% for kittens)
- Amino acids like taurine, arginine, and methionine
- Animal fats for energy and essential fatty acids
- Vitamins A, D, E, and B-complex from animal sources
- Minerals like calcium, phosphorus, and magnesium
- Plenty of water to maintain kidney and urinary health
Cats can’t convert plant-based nutrients efficiently. They require preformed vitamin A, arachidonic acid, and taurine, all found naturally in animal tissues. A deficiency in these can cause blindness, heart disease, and other severe issues.
Decoding Cat Food Labels
Reading labels helps you choose the best food for your cat. Ingredients are listed by weight, so prioritize foods that list a specific meat (like “chicken” or “salmon”) first. Avoid vague terms such as “meat by-products” or “animal digest.”
Watch Out For
- Generic meat sources or meals
- Fillers like corn, wheat, or soy
- Artificial preservatives (BHA, BHT, ethoxyquin)
- Sugars and sweeteners
Look For
- Named meat proteins
- Whole food ingredients (peas, sweet potato, blueberries)
- Added taurine, omega-3s, and probiotics
- AAFCO statement confirming nutritional adequacy
Guaranteed Analysis
Typical values for adult cats:
- Protein: 26–30%
- Fat: 9%+
- Fiber: 3–5%
- Moisture: 10–12% (dry) or 75–80% (wet)
To compare wet and dry food, use a dry matter basis—remove moisture percentage to get an accurate comparison of nutrients.
Wet vs. Dry Food
Wet Food
Contains 75–80% moisture, which supports hydration and mimics a cat’s natural prey diet.
Pros:
- Promotes urinary and kidney health
- Higher in protein, lower in carbs
- More palatable and easier to digest
Cons:
- Costlier and spoils quickly
- Can cause plaque buildup if used alone
Dry Food
Dry kibble is convenient and affordable but lacks moisture.
Pros:
- Easy to store and feed
- Helps reduce tartar buildup
- Suitable for automatic feeders
Cons:
- Only 10–12% moisture
- Often higher in carbs and fillers
- Encourages overeating if free-fed
Best Approach
Combine both: wet food for hydration and protein, and dry food for convenience and dental health. Feed wet meals twice daily and leave a small amount of kibble for grazing.
Feeding by Life Stage
Kittens (0–12 Months)
Kittens grow rapidly and need high-protein, high-calorie food rich in DHA for brain development.
Feeding Schedule:
- 0–4 weeks: mother’s milk or formula
- 4–8 weeks: introduce wet kitten food
- 2–6 months: 3–4 small meals/day
- 6–12 months: transition to 2–3 meals/day
Example: A 6-week-old kitten like “Whiskers,” fed four small meals of high-protein wet food daily, can reach healthy weight and energy levels within weeks.
Adult Cats (1–7 Years)
Focus on maintenance—balancing calories with activity to prevent obesity.
- 2 meals daily (or 3 smaller ones)
- Feed for ideal, not current, weight
- Adjust calories for activity (indoor cats need less)
- Average: ~20 calories per pound of body weight
You should feel, but not see, your cat’s ribs. Adjust portions if weight increases.
Senior Cats (7+ Years)
Older cats may face slower metabolism, dental issues, and kidney disease.
- Choose highly digestible proteins
- Prioritize moisture-rich foods
- Add joint-supporting supplements (glucosamine, chondroitin)
- Feed smaller, more frequent meals
Talk to your vet about switching to a senior formula around age 7–10, especially if chronic conditions appear.
Portion Control and Calorie Calculation
Overfeeding is the #1 nutrition mistake. About 60% of U.S. cats are overweight, leading to diabetes, arthritis, and heart disease.
Daily Calorie Formula
RER = 70 × (weight in kg)^0.75
Then multiply by an activity factor:
- Neutered adult: ×1.2
- Intact adult: ×1.4
- Kitten: ×2.5
- Senior: ×1.1
- Weight loss: ×0.8
Feeding Tips
- Use a kitchen scale or measuring cup—don’t eyeball portions
- Feed on a consistent schedule
- Remove uneaten wet food after 30 minutes
- Avoid free-feeding
- Try puzzle feeders to slow fast eaters
- Weigh your cat monthly to track trend
Special Dietary Considerations
Food Allergies
Allergies often cause skin irritation or digestive issues. Common culprits include beef, dairy, and fish.
If suspected, try an elimination diet with limited ingredients or hydrolyzed proteins for 8–12 weeks under vet supervision.
Urinary Health
Urinary tract problems are common. Specialized diets help by:
- Controlling minerals (magnesium, phosphorus)
- Adjusting urine pH
- Promoting water intake
Weight Management
For overweight cats:
- Reduce calories by 20–30%
- Feed more protein, fewer carbs
- Encourage daily play sessions
- Aim for 1–2% body weight loss per week
- Avoid rapid weight loss—it can cause fatty liver disease
Hydration: The Hidden Key to Health
Cats often don’t drink enough water, leading to chronic dehydration and kidney issues.
Hydration Tips
- Offer multiple bowls around the house
- Use wide, shallow dishes to prevent whisker fatigue
- Try a cat fountain (cats love running water)
- Add water or low-sodium broth to food
- Feed mostly wet food
- Keep bowls clean and water fresh daily
Signs of dehydration: sunken eyes, dry gums, poor skin elasticity, lethargy.
If observed, seek veterinary attention immediately.
Foods to Avoid
Certain foods are toxic or dangerous to cats:
Toxic Foods
- Onions, garlic → cause anemia
- Chocolate → contains toxic theobromine
- Grapes/raisins → cause kidney failure
- Alcohol, xylitol → deadly even in small amounts
- Raw dough → expands, releases alcohol
- Cooked bones → splinter and cause internal damage
Foods to Limit
- Dairy → most cats are lactose intolerant
- Raw eggs or fish → risk of bacteria and nutrient loss
- Tuna → high mercury; use sparingly
- Dog food → lacks taurine and essential nutrients
Treats and Supplements
Treats should make up no more than 10% of daily calories.
Healthier Treat Options
- Freeze-dried meat (chicken, salmon)
- Low-calorie or dental treats
- Hairball or joint-support varieties
When to Use Supplements
If your cat eats a complete, balanced diet, supplements aren’t usually necessary. However, certain cats benefit from:
- Omega-3s (for skin, joints, inflammation)
- Probiotics (digestive health)
- Vitamin B12 (for digestive disorders)
- Joint support for older cats
Always consult your vet before adding supplements—overdosing vitamins and minerals can be harmful.

Transitioning to a New Food
Cats resist sudden diet changes. Transition gradually over 7–10 days to avoid stomach upset:
| Days | Old Food | New Food |
| 1–2 | 75% | 25% |
| 3–4 | 50% | 50% |
| 5–6 | 25% | 75% |
| 7+ | 0% | 100% |
If vomiting or diarrhea occurs, extend the transition period.
Frequently Asked Questions
How often should I feed my cat?
Adults: 2–3 meals/day. Kittens: 3–4 meals/day. Scheduled meals help prevent overeating.
Is grain-free better?
Not always. Grains aren’t harmful; focus on high protein and meat-based ingredients instead of marketing terms.
Can cats be vegan?
No. Cats need nutrients found only in meat (like taurine and vitamin A). A vegan diet can cause blindness or heart failure.
Why does my cat eat grass?
It may aid digestion or induce vomiting to clear hairballs. Offer safe cat grass indoors.
How do I know if my cat is overweight?
You should feel ribs easily and see a waist from above. If not, reduce portions and increase playtime.
Should I feed raw food?
Raw diets carry bacterial risks and must be precisely balanced. Consult a vet nutritionist before attempting it.
How much water should my cat drink?
Roughly 3.5–4.5 ounces per 5 pounds of body weight daily, including water from food.
Can I make homemade cat food?
Yes, but only with professional guidance. Improperly balanced recipes can lead to nutrient deficiencies.
