Introduction
Proper nutrition is the cornerstone of your cat's health and longevity. This guide covers everything from selecting high-quality cat food to establishing feeding routines tailored to your feline's life stage, size, and activity level.
Recommended Diet Types
Dry Food (Kibble)
Convenient and economical, dry food has a long shelf life and helps reduce tartar buildup. However, it contains less moisture and may be higher in carbohydrates. Look for brands with named meat as the first ingredient and moderate protein (30-40%) and fat (15-20%) content.
Wet Food (Canned)
With about 75-85% moisture, wet food supports hydration and is closer to a cat's natural diet. It's especially beneficial for cats with urinary tract issues or those that don't drink enough water. Choose products with high protein, moderate fat, and minimal carbohydrates.
Raw Food (Raw Meat-Based Diets)
Proponents claim raw diets mimic ancestral eating. Commercial raw foods are nutritionally balanced, while homemade raw diets require careful supplementation. Risks include bacterial contamination and nutritional imbalances if not properly formulated.
Homemade Cooked Food
Homemade diets allow total control over ingredients but must be carefully balanced with supplements like taurine, calcium, and vitamins. Always consult a veterinary nutritionist before switching to homemade food.
Portion Sizes and Daily Calorie Needs
Calorie requirements vary by age, weight, and activity level. Use the table below as a starting point, adjusting based on your cat's body condition.
| Cat Weight | Activity Level | Daily Calories (kcal) |
|---|---|---|
| 4-5 kg (9-11 lbs) | Sedentary | 180-220 |
| 4-5 kg (9-11 lbs) | Active | 220-270 |
| 5-6 kg (11-13 lbs) | Sedentary | 220-260 |
| 5-6 kg (11-13 lbs) | Active | 260-320 |
Kittens (under 1 year) need 2-3 times the calories per pound as adults. Senior cats (over 7 years) often require slightly fewer calories due to decreased activity. Use a food scale for accuracy.
Feeding Frequency and Schedule
- Kittens (0-6 months): 3-4 meals per day.
- Kittens (6-12 months): 3 meals per day.
- Adults (1-7 years): 2 meals per day, ideally 8-12 hours apart.
- Seniors (7+ years): 2-3 smaller meals per day if appetite declines.
Free-feeding (leaving food out all day) is not recommended as it can lead to obesity. Cats are natural grazers, so portioned meals are better.
Essential Nutrients
Protein
Cats are obligate carnivores and require high-quality animal protein (e.g., chicken, fish, beef). A minimum of 26% protein in dry matter is recommended; optimally 30-40%.
Fat
Fat provides energy and essential fatty acids like arachidonic acid. Aim for 15-25% fat in dry matter. Omega-3 and omega-6 fatty acids support skin, coat, and joint health.
Carbohydrates
Cats have no dietary need for carbs, but small amounts from vegetables or grains can be used as fillers. Diets with more than 10-15% carbs may contribute to obesity and diabetes.
Vitamins and Minerals
Key vitamins: A (preformed from animal sources), D, E, K, B-complex. Taurine is an essential amino acid critical for heart and eye health—must be supplemented in all commercial cat foods. Calcium and phosphorus ratios should be balanced (1.1 to 1.5:1).
Foods Toxic or Harmful to Cats
- Onions and garlic: Can cause hemolytic anemia.
- Grapes and raisins: Linked to kidney failure.
- Chocolate: Contains theobromine, toxic even in small amounts.
- Xylitol: Artificial sweetener causing hypoglycemia and liver damage.
- Raw eggs and raw fish: Risk of salmonella and thiamine deficiency.
- Alcohol and caffeine: Highly dangerous.
- Dairy products: Many adult cats are lactose intolerant, leading to digestive upset.
Water Intake Recommendations
Cats evolved from desert ancestors and have a low thirst drive. Encourage hydration by:
- Providing fresh, clean water in multiple bowls.
- Using a cat water fountain (running water attracts them).
- Feeding wet food (at least 50% of diet).
- Adding water or broth to dry food.
A cat should consume roughly 60 ml of water per kg of body weight per day (about 250 ml for a 4 kg cat).
Beneficial Supplements
- Omega-3 fatty acids: From fish oil, supports skin, coat, joints, and kidneys.
- Probiotics: Improve digestion and immune health.
- Joint supplements: Glucosamine and chondroitin for aging or arthritic cats.
- Taurine: Critical for heart and eyes; already in balanced commercial diets but needed if feeding homemade.
- Digestive enzymes: May help cats with pancreatic insufficiency.
Always consult your veterinarian before adding supplements.
Feeding Differences by Life Stage
Kittens (0-12 months)
Need high-protein, high-calorie diets (30-40% protein, 25-30% fat) for growth. Feed kitten-formulated food until 12 months of age. Include DHA for brain development.
Adults (1-7 years)
Maintain balanced nutrition with moderate calories. Adjust portions to prevent weight gain. Spaying/neutering lowers calorie needs by about 20-30%.
Seniors (7+ years)
Often need lower phosphorus and sodium to support aging kidneys. Increased digestible protein (to preserve muscle) and joint supplements. More frequent, smaller meals if appetite wanes.
Signs of Healthy vs. Poor Diet
Healthy Diet Indicators
- Shiny, soft coat with minimal shedding.
- Bright, clear eyes.
- Clean teeth and gums without halitosis.
- Consistent, firm stools (not too hard or soft).
- Ideal body condition: ribs easily felt but not visible, waist visible from above.
- Good energy levels and alertness.
Poor Diet Indicators
- Dull, greasy, or flaky coat; hair loss.
- Lethargy or hyperactivity.
- Chronic vomiting or diarrhea.
- Excessive weight gain or loss.
- Bad breath, dental disease.
- Frequent urinary tract infections or kidney issues.
- Dull eyes or runny nose.
If you notice any of these signs, consult a veterinarian to adjust your cat's diet.
