Feeding Your Cat: A Complete Guide to a Balanced Diet

Providing your cat with a complete and balanced diet is one of the most important ways to support their long-term health, wellbeing, and quality of life.

Complete, meaning the food has all 43 essential nutrients for cats and balanced, meaning these essential nutrients are in the correct ratios of each other (you actually CAN have too much of a good thing!).

Cats have very specific nutritional needs, and feeding the wrong diet - even with good intentions - can lead to serious health problems over time.

This guide will help you understand what you cat needs and how to feed them appropriately at every stage of life.

A balanced diet provides all the essential nutrients your cat needs in the correct portions.

These include:

• Protein - essential for muscle maintenance and overall health
• Fats - a key source of energy
• Vitamins and minerals - for organ function and immune health
• Water - critical for hydration and kidney function

Cats are obligate carnivores, meaning they must eat animal-based protein to meet their nutritional requirements. 

Diets that are not properly balanced (such as feeding only meat or homemade diets without guidance) can lead to nutritional deficiencies which lead to numerous diseases over time - some of which are fatal.

Your cat's nutritional needs change as they grow and age.

Kittens

• Require higher energy and protein
• Should be fed specially formulated kitten diets as kittens have different essential nutrients to adults
• Need multiple small meals throughout the day
• Premium kitten diets have DHAs for vision and brain development

• Require a balanced maintenance diet
• Portion control is important to prevent obesity
• Feeding routines should be consistent

• May require diets tailored to kidney health, weight management, or joint support
• Appetite and digestion can change
• Regular monitoring is important

The amount you feed depends on:

• Age
• Weight
• Activity level
• Health status

Always use feeding guides as a starting point, but adjust based on your cat's body condition.

If you're unsure, your vet can help determine the right portion size for your cats.

Obesity is one of the most common health problems in cats. Adipocytes (fat cells) constantly release inflammatory mediators - causing exacerbating inflammation throughout the body, this can lead to:

• Diabetes
• Arthritis
• Hepatic lipidosis (liver issues)
• Kidney disease
• Cancer
• Bladder stones
• Respiratory disease
• Reduced lifespan

Signs your cat may be overweight:

• You cannot easily feel their ribs
• They have a rounded body shape
• Reduced activity

Even small weight changes can make a big difference to your cat's health.

Even well-meaning owners can accidentally feed incorrectly.

Common mistakes include:

• Feeding only meat (not nutritionally balanced as low in calcium but high in phosphorous)
• Feeding dog food to cats
• Overfeeding or too many treats

A consistent, complete and balanced diet is key to long-term health.

Cats can often benefit from exposure to a variety of flavours and textures, particularly when fed complete and balanced diets.

Introducing variety gradually may help:

• Reduce fussiness
• Increase dietary acceptance
• Provide nutritional variety between diets

However, sudden or frequent changes between multiple foods at once can sometimes lead to digestive upset.

When changing diets:

• Transition gradually over several days
• Avoid mixing too many different foods at once
• Ensure all diets are complete and balanced

Most common cat foods labelled "complete and balanced" are formulated to meet all of your cat's nutritional needs.

You can feed raw diets, however it's very difficult to do and works out quite expensive.

Homemade or raw diets can be fed, but:

• Must be carefully balanced
• Often require specialist veterinary guidance
• Can pose risks if not prepared correctly

If you are considering a homemade or raw diet, it's important to discuss this with your veterinarian first or visit vngpets.com as this is a website by veterinarians who are specialists in nurtition.

Many cats do not drink enough water, which can contribute to urinary and kidney problems.

To encourage hydration:

• Provide fresh water daily
• Unlike dogs, cats should be fed wet food
• Use multiple water sources or Fountains
• Try adding more water to your cat's wet food to increase intake

You should seek advice if your cat:

• Is gaining or losing weight unintentionally
• Has reduced or increased appetite
• Is vomiting frequently - this is never normal for cats
• Has changes in drinking or urination
• Has specific health conditions, as diet can be therapeutic for different conditions

Nutrition plays a major role in managing and preventing numerous medical conditions - most importantly kidney disease!

Feeding your cat a complete and balanced diet doesn't need to be complicated - but it does need to be correct.

A good diet supports:

• Healthy weight
• Strong muscles
• Organ function
• Long-term wellbeing
