Adult cats are obligate carnivores. Their bodies are designed to get energy, essential amino acids, and vital nutrients from animal-based protein.

The right quality and amount of protein in their diet isn’t a luxury — it’s absolutely essential for their strength, well-being, and long, healthy life.

Why is protein so important for cats?

Protein supports:

• Strong muscles & mobility
• Energy for playful zoomies and couch-to-ceiling acrobatics
• A healthy immune system and antibody production
• Shiny fur & healthy skin
• Proper organ function and enzyme production
• Hormonal balance

Protein deficiency may show up as hair loss, weakness, weight or muscle loss, and low appetite.

The magic of animal protein:

• Amino acids
• Cats need certain amino acids only found in animal protein:

Amino Acid Role

• Taurine Heart, vision, reproduction
• Arginine Metabolism, ammonia detoxification
• Methionine & Cysteine Skin and coat health
• Tryptophan Mood and sleep support

Plant protein alone is not enough for cats.

Best sources of high-quality protein in cat food

Look for:

• Fresh meat such as chicken, turkey, beef, lamb
• Fish like salmon and tuna (in moderation)
• Eggs

What to check on the label:

• Better quality
• “Fresh meat”
• “Animal protein”
• “High-quality meat meal”

Less ideal

• “Animal derivatives”
• “By-products” (without specifying the source)

How much protein does an adult cat need?

In a balanced diet:

≥ 30% crude protein in dry cat food

≥ 8–10% in wet food (lower because of high moisture)

Active cats – and neutered cats – often benefit from higher protein under proper guidance.

Wet vs Dry Cat Food: Who wins on protein?

• Dry food is usually more concentrated in protein
• Wet food supports hydration and often uses more visible animal ingredients

For most cats, the best formula is a mixed feeding plan!

What about too much protein?

Healthy cats generally tolerate and utilize protein very well. Exception: chronic kidney disease. In that case, diet must be adapted with veterinary supervision.

How to choose the right food on the shelf

• Animal protein as the first ingredient
• Clear source labeling (“chicken,” not “poultry derivatives”)
• Appropriate protein percentage
• Good digestibility — avoid excessive fillers

Great protein in the bowl = shiny coat, strong muscles, playful spirit, and a happy kitty cuddling by your side.

FAQ – Frequently Asked Questions

1. Is taurine necessary in cat food?

Absolutely. Cats cannot produce enough taurine on their own — it must come from their food.

2. Can I feed my cat dog food?

No! Dog food doesn’t contain enough protein and taurine for feline needs.

3. How can I tell if protein is high quality?

If a named animal protein appears first on the ingredient list and the source is clearly defined.

4. Is plant-based protein enough for cats?

No. Cats require animal protein to meet essential amino acid needs.
