Natural Feeding for Cats: What to Feed Cats Instead of Just Kibble

By Dr Duncan Houston

Quick Answer

Cats are obligate carnivores, which means they need a diet built primarily from animal-based ingredients, not carbohydrates or plant-heavy fillers. A natural cat diet can work very well when it provides the right balance of animal protein, fat, moisture, and essential nutrients such as taurine and calcium.

As a veterinarian, I take feline nutrition seriously because cats are far less forgiving than dogs when diets are poorly balanced. They can look fine for a while, then quietly develop serious nutritional or urinary issues if the diet is not right.

Why Cats Need a Different Diet from Dogs

Cats are true carnivores.

They are designed to get key nutrients from animal tissue, including:

• Taurine

• Arachidonic acid

• Preformed vitamin A

• High-quality animal protein

• Moisture from food

They do not handle a plant-heavy diet the way dogs or people can. Their nutritional needs are more specific and less flexible.

Why Natural Feeding Makes Sense for Cats

One of the biggest problems with many feline diets is that they are too dry and too carbohydrate-heavy.

A natural feeding approach can help:

• Increase moisture intake

• Better reflect a cat’s biological needs

• Improve palatability

• Support urinary and kidney health

• Provide more animal-based nutrition

Cats often do best when their diet looks more like prey and less like tiny brown biscuits with a marketing budget.

The Most Important Parts of a Natural Cat Diet

Animal protein comes first

The foundation of a cat’s diet should be animal protein.

Suitable options may include:

• Chicken

• Turkey

• Rabbit

• Duck

• Lamb

• Beef

• Fish in appropriate amounts

This protein should come from a complete and balanced diet if commercially prepared, or from a properly formulated recipe if home prepared.

Fat matters too

Cats use fat as an important energy source.

Animal fats help support:

• Energy levels

• Skin and coat health

• Palatability

• Nutrient absorption

The goal is not low fat. It is appropriate fat from the right sources.

Organ meats provide critical nutrients

Organs such as:

• Liver

• Heart

• Kidney

can provide important micronutrients, but they need to be fed in the correct balance.

Too little can create deficiencies. Too much, especially liver, can create other problems.

Moisture is non-negotiable

This is one of the most important points in feline nutrition.

Cats naturally have a low thirst drive, which means they are designed to get much of their water from food.

Moisture-rich diets can help support:

• Urinary tract health

• Kidney function

• Overall hydration

This is one reason many cats do better on wet, raw, or home-prepared diets than on dry kibble alone.

Natural Feeding Options for Cats

Complete and balanced commercial raw or cooked diets

This is often the easiest and safest option for beginners.

A good commercial natural diet should be:

• Complete and balanced for cats

• Formulated specifically for feline requirements

• Consistent in nutrient profile

This makes life much easier because feline nutrition is not something to freestyle.

Home-prepared diets

These can work very well, but only if properly formulated.

Home-prepared cat diets usually need:

• Precise recipes

• Taurine supplementation

• Calcium balancing

• Vitamin and mineral support

• Careful weighing and consistency

Cats are not good candidates for casual “a bit of this and a bit of that” feeding.

Key Nutrients You Cannot Ignore

Taurine

Essential for:

• Heart function

• Eye health

• Reproductive health

Taurine deficiency in cats can be serious and sometimes irreversible.

Calcium

Needed for bone health and correct mineral balance.

Feeding only meat without calcium is one of the biggest mistakes in homemade feeding.

Omega 3 fatty acids

Helpful for:

• Skin and coat

• Inflammation support

• Overall health

Vitamins and trace minerals

Cats need the right balance, not just meat quantity.

Why Kibble Is Not Ideal as the Whole Diet

Dry food is not automatically evil, but it has limitations.

It is typically:

• Much lower in moisture

• Often higher in carbohydrates

• Less aligned with natural feline hydration patterns

For some cats, especially those prone to urinary or kidney issues, a dry-only diet is not ideal long term.

Hydration Should Always Be a Priority

Even when feeding naturally, hydration still matters.

Helpful strategies include:

• Feeding wet or fresh food

• Offering fresh water in multiple locations

• Using wide, clean bowls

• Adding water to meals if tolerated

Cats are famously odd about water, as if hydration is a personal insult, so making it easy and appealing matters.

What to Avoid

• Feeding only muscle meat

• Using dog food as a main diet

• Overfeeding liver

• Ignoring taurine needs

• Feeding unbalanced homemade food long term

• Assuming a cat can adapt to a nutritionally weak diet because they “seem fine”

Cats often hide problems well, which is exactly why getting their diet right matters.

Whole Foods and Minimally Processed Feeding

Natural feeding can be an excellent approach for cats because it:

• Prioritises animal-based nutrition

• Supports hydration

• Reduces reliance on heavily processed dry food

• Better matches feline biology

But natural only works well when it is also balanced.

That is the difference between a biologically appropriate diet and a nutritional accident.

Final Thoughts

Natural feeding for cats can be a very good option when done properly.

The main priorities are:

• Animal-based nutrition

• Moisture

• Correct nutrient balance

• Consistency

Cats do not need trendy feeding. They need species-appropriate feeding.

FAQs

Can I feed my cat raw food?
Yes, but it should be complete and balanced if commercial, or properly formulated if home prepared.

Is kibble bad for cats?
Not automatically, but dry-only feeding is often not ideal because cats naturally need more moisture than kibble provides.

Do cats need supplements on a home-cooked diet?
Yes, in most cases absolutely. Taurine, calcium, and other nutrients are critical.
