Cat Feeding Guide: Nutritional Needs, Portions, and Tips

Source : dailypaws

Feeding your cat the right amount of food is crucial for maintaining its health and well-being. Overfeeding can lead to obesity, while underfeeding can cause nutritional deficiencies.

This guide will help you understand how much you should feed your cat, taking into consideration various factors such as age, weight, activity level, and the type of food you choose.

Understanding Your Cat's Nutritional Needs

Cats are obligate carnivores, meaning they require a diet primarily composed of meat. Their nutritional needs are distinct from those of dogs and humans. Essential nutrients for cats include proteins, fats, vitamins, and minerals.

Here’s a breakdown of these nutrients:

  1. Proteins: Essential for growth, repair, and maintenance of body tissues.
  2. Fats: Provide energy and help absorb certain vitamins.
  3. Vitamins and Minerals: Necessary for various bodily functions, including immune response and bone health.

Factors Influencing Your Cat's Dietary Needs

Several factors influence how much you should feed your cat. These include:

  1. Age: Kittens, adults, and senior cats have different nutritional needs.
  2. Weight: Overweight and underweight cats require different feeding strategies.
  3. Activity Level: Active cats burn more calories than sedentary ones.
  4. Health Status: Cats with certain health conditions may need special diets.


Kittens: Kittens need more calories and nutrients than adult cats to support their rapid growth and development. They typically require food formulated specifically for kittens, which is higher in protein and fat.

Adults: Adult cats need a balanced diet that maintains their health and weight. Their calorie requirements are lower than those of kittens.

Seniors: Senior cats may require diets that are easier to digest and contain more fiber. They might also need lower-calorie food if they are less active.


Underweight Cats: If your cat is underweight, you may need to increase its food intake or switch to a more calorie-dense food.

Overweight Cats: For overweight cats, portion control and lower-calorie food can help manage their weight.

Activity Level

Active Cats: Cats that are very active, such as outdoor cats, may need more calories to maintain their energy levels.

Sedentary Cats: Indoor cats or those with lower activity levels will require fewer calories.

Types of Cat Food

Cat food comes in various forms, each with its own feeding guidelines. The three main types are dry food, wet food, and raw food.

Dry Food

Dry food is convenient, has a long shelf life, and helps maintain dental health by reducing tartar buildup. However, it’s typically lower in moisture content, so it’s important to ensure your cat drinks enough water.

Feeding Guidelines: The packaging usually provides feeding guidelines based on your cat's weight. On average, cats need about 20-30 calories per pound of body weight per day. For a 10-pound cat, this translates to approximately 200-300 calories per day.

Wet Food

Wet food contains more moisture, which is beneficial for cats that do not drink much water. It’s also more palatable for many cats.

Feeding Guidelines: Cans or pouches of wet food often include feeding recommendations. Generally, one 5.5-ounce can of wet food contains about 150-200 calories. A 10-pound cat might need one can per day, divided into two meals.

Raw Food

Raw food diets mimic what cats would eat in the wild. They consist of raw meat, bones, and organs.

Feeding Guidelines: These diets require careful preparation and handling to ensure they meet all of a cat’s nutritional needs and to avoid contamination. Consult with a veterinarian to develop a balanced raw food diet plan.

Calculating Your Cat’s Caloric Needs

To calculate your cat's daily caloric needs, you can use the Resting Energy Requirement (RER) formula:

RER=70×(body weight in kg)0.75

RER=70×(body weight in kg)


Then, multiply the RER by a factor based on your cat’s life stage and activity level:

Kittens (0-4 months): RER × 2.5
Kittens (4 months to 1 year): RER × 2
Neutered Adult Cats: RER × 1.2-1.4
Active Adult Cats: RER × 1.4-1.6
Obese-Prone Cats: RER × 1.0
Weight Loss: RER × 0.8

Monitoring Your Cat’s Weight and Health

Regularly monitoring your cat’s weight and health is essential to ensure they are receiving the right amount of food. Here are some tips:

  1. Weigh Your Cat: Use a pet scale or a household scale to weigh your cat regularly. Keep track of the weight to notice any significant changes.
  2. Body Condition Score (BCS): The BCS is a visual assessment of a cat’s body fat. It ranges from 1 (emaciated) to 9 (obese). A score of 5 is ideal. You should be able to feel your cat’s ribs but not see them.
  3. Consult Your Vet: Regular veterinary check-ups are important. Your vet can help you adjust your cat’s diet based on its health and nutritional needs.

Transitioning to a New Diet

When changing your cat’s diet, do so gradually over a week to avoid digestive upset:

Days 1-2: 75% old food, 25% new food.
Days 3-4: 50% old food, 50% new food.
Days 5-6: 25% old food, 75% new food.
Day 7: 100% new food.

Special Dietary Needs

Some cats have special dietary needs due to health conditions:

  1. Diabetes: Diabetic cats may require a high-protein, low-carbohydrate diet.
  2. Kidney Disease: Cats with kidney disease often need a diet low in phosphorus and protein.
  3. Allergies: Hypoallergenic diets may be necessary for cats with food allergies.

Homemade Diets

Some pet owners prefer to prepare homemade diets for their cats. If you choose this route, it’s crucial to ensure the diet is balanced and meets all of your cat’s nutritional needs. Consulting with a veterinary nutritionist is recommended.

Tips for Encouraging Healthy Eating Habits

  • Set a Feeding Schedule: Consistency helps regulate your cat’s digestion and can prevent overeating.
  • Portion Control: Measure your cat’s food to avoid overfeeding.
  • Interactive Feeding: Use puzzle feeders or food-dispensing toys to stimulate your cat’s mind and encourage physical activity.

Common Feeding Mistakes

  • Free Feeding: Leaving food out all day can lead to overeating and obesity.
  • Over-Treating: Treats should not make up more than 10% of your cat’s daily caloric intake.
  • Ignoring Water Intake: Ensure your cat has access to fresh water, especially if it eats dry food.

Feeding your cat the right amount involves understanding its unique needs and carefully monitoring its health.

By considering factors such as age, weight, activity level, and health status, and choosing the appropriate type of food, you can ensure your cat maintains a healthy weight and receives the necessary nutrients for a long, happy life.

Regular vet visits and adjustments to the diet as needed will help keep your feline friend in optimal health.
