When it comes to feline nutrition, organ meats often take a backseat to more familiar cuts, yet they hold a treasure trove of benefits for our feline friends.

This article uncovers the following:


What Are Organ Meats?

Organ meats from different food animals


Organ meats, also known as offals, are vital components of a raw diet that include a variety of animal organs such as the liver, kidney, heart, brain, and pancreas, each offering unique health benefits. 


These nutrient-dense foods are rich in vital nutrients like omega-3 fatty acids, B vitamins, iron, and essential hormones that contribute to a well-ba lanced diet for carnivorous pets, such as cats. 


Why Are Organ Meats Important for Cats?

Organ meats play a crucial role in the health and nutrition of cats, providing a concentrated source of essential nutrients that support their overall well-being.


Unlike some commercial pet food, which lack certain vital components, organ meats are rich in protein, vitamins, and minerals that are vital for maintaining healthy muscle tissue, immunity, and proper organ function in felines. Table 1 shows some of the nutrient contents of Beef Kidney according to USDA.


“Taurine is essential for cats due to its limited biosynthetic capability and bile salt metabolism, and deficiency can lead to serious clinical problems like retinal degeneration, poor reproductive performance, and dilated cardiomyopathy.,” according to the 1995 study by Markwell, P., & Earle, K. 

By incorporating these nutrient-dense meats into their diet, cat owners ensure their pets receive a balanced and wholesome nutritional profile.


What Nutrients Do Organ Meats Provide for Cats?


Organ meats are packed with essential nutrients that are crucial for a cat's health, including high-quality protein, vitamin A, omega-3 fatty acids, iron, and taurine, which are vital for maintaining energy levels and overall vitality. These nutrients support various bodily functions such as healthy digestion, skin, coat, and muscle tissue maintenance.


By incorporating organ meats into a cat's diet, pet owners provide their feline companions with a rich source of these vital nutrients.

Organ meats offer a concentrated source of B vitamins, including B12 and riboflavin, which are important for energy metabolism and red blood cell formation. In contrast, a diet lacking these essential nutrients lead to problems like anemia, poor coat condition, and weakened immune response.

To ensure that felines thrive, it’s important for caretakers to recognize the significance of a varied diet, enriched with organ meats.

  • Iron: Helps in the formation of hemoglobin, essential for oxygen transport.

  • Taurine: Crucial for heart health and eye function.

  • Vitamin A: Supports vision and immune system function.

  • Omega-3 Fatty Acids: Promote a healthy coat and reduce inflammation.


Ultimately, a balanced approach to nutrition, incorporating a variety of protein sources including organ meats, is fundamental for optimal health and longevity in cats.


What Are the Best Types of Organ Meats for Cats?

When considering the best types of organ meats for cats, liver, kidney, heart, and brain stand out as the most nutrient-dense options. Each of these organ meats offers unique health benefits.

  • Liver: The liver is a highly nutritious organ meat for cats, providing essential vitamins and minerals such as vitamin A, iron, and B vitamins. It supports vision, immune function, and overall health. However, it should be served in moderation to avoid vitamin A toxicity. It's best to consult with a veterinarian to determine the appropriate serving size, typically limited to 1-2 small pieces per week for an average-sized cat. Properly cooked liver is a beneficial supplement to a cat's diet, enhancing their overall health.

  • Kidney: The kidney is a highly nutritious organ meat for cats, providing essential minerals and vitamins. It supports kidney function, metabolic processes, muscle maintenance, and neurological health. Introduce it gradually, sourced from a reputable provider.

  • Heart: The heart is a great source of protein and taurine, essential for cats' muscle mass and energy. It supports heart health and overall vitality. Adding heart meat to the cat's diet provides essential nutrients, including taurine, vital for vision and reproductive health. Mix cooked heart meat with regular kibble or incorporate it into homemade cat food recipes as a special treat.

  • Brain: The brain is a beneficial organ meat for cats, providing omega-3 fatty acids crucial for cognitive function and overall brain health. It enhances the immune system, promotes healthy skin and coat, and positively influences bodily functions. Omega-3 fatty acids have anti-inflammatory properties, aiding brain health and joint mobility. Additionally, brain meat improves learning abilities, memory, and mental sharpness in cats while strengthening their immune system. When adding a brain to a cat's diet, it's important to cook it gently at a low temperature to retain nutrients, source it from reputable suppliers, and introduce it gradually to monitor for any adverse reactions. With proper preparation, the brain significantly contributes to a cat's overall health and vitality.


“Cats show a preference for liver and kidney in pet food components, and prefer lamb over equivalent beef components, with mechanically deboned meat being the least palatable,” according to the 2020 study by Watson, P., Thomas, D., Hoggard, A., Parker, M., & Schreurs, N.

How Much Organ Meat Should Cats Consume?

As a general guideline, organ meats should make up about 5-10% of a cat's total diet or about a tablespoon a few times a week, ensuring that they receive a variety of nutrients while avoiding excessive intake of any single organ. Heart is fed more liberally, up to about 10% of the diet, due to its high taurine content. A beef heart has 3461mg taurine/kg dry weight according to the 2003 study by Spitze, A., Wong, D., Rogers, Q., & Fascetti, A.


“The highest taurine concentration in fish hearts was found in cod at 8.3 mg/g and salmon at 5.6 mg/g,” according to the 2009 study by Dragnes, B., Stormo, S., Larsen, R., Ernstsen, H., & Elvevoll, E.

Determining the appropriate amount of organ meat for cats is essential for maintaining a well-balanced diet and preventing issues such as hypervitaminosis A or nutrient deficiencies. 


How to Incorporate Organ Meats into a Cat's Diet?

Incorporating organ meats into a cat's diet is achieved through raw feeding, homemade cat food recipes, or selecting commercial cat food that contains organ meats. Each approach allows pet owners to ensure their feline companions benefit from the rich nutrients found in these vital food sources while promoting healthy digestion and overall well-being.

  • Raw Diet: This approach mimics a cat's natural prey model diet, ensuring they receive a variety of nutrients and promoting healthy digestion. Follow recipes specifically designed for raw feeding that include the right proportions of organ meats, muscle meats, and bones. Grind the organ meats and mix them with muscle meat and other components to create a balanced meal. Precaution is crucial; always ensure meats are fresh and sourced from reputable suppliers. Introducing raw food gradually can help avoid digestive upset and allow the cat to adjust to the new diet smoothly.

  • Cooked Diet: Creating homemade cat food allows pet owners to have complete control over the ingredients, ensuring that organ meats are included for their nutrient density while avoiding harmful additives commonly found in commercial options. Lightly cooking organ meats makes them more palatable for some cats. Ensure they are cooked thoroughly to kill any potential pathogens, but avoid overcooking to retain nutrients.  Incorporate small amounts of cooked organ meats into the cat's regular food. Gradually increase the amount as they get used to it. 

  • Commercial Diet: Many reputable brands incorporate organ meats like liver, kidney, and heart into their recipes, catering to a cat's carnivorous dietary needs.

  • Pre-made Raw Meals: Consider commercially prepared raw food diets formulated to include the right balance of organ meats.

  • High-Quality Wet or Dry Food: Some high-quality commercial cat foods include organ meats in their formulations.

  • Freeze-Dried Organ Treats: Use freeze-dried organ meats as treats or meal toppers. They are convenient and add nutritional benefits without requiring preparation.

  • Organ Meat Supplements: There are supplements available that provide the benefits of organ meats in a convenient form.


Are There Any Risks of Feeding Organ Meats to Cats?


While organ meats are highly beneficial for cats, there are risks associated with their consumption, including potential allergies, vitamin A toxicity from excessive liver intake, and contamination from poor handling or sourcing. Pet owners need to be aware of these risks to ensure their cats thrive and avoid health complications.


Allergies


When introducing new foods into a cat's diet, it's important to be cautious as allergies manifest in various ways. Common allergic reactions include excessive scratching or licking, vomiting or nausea, and swelling of the face or paws. If a potential allergen is suspected, consulting with a veterinarian for proper diagnosis and tailored dietary solutions is essential. Understanding the pet’s unique dietary needs and making adjustments as necessary is vital.


“Food hypersensitivity in cats often causes pruritic dermatosis, miliary dermatitis, self-induced alopecia, and gastrointestinal involvement, with common allergens being beef, lamb, milk, fish, tinned food, and dried food,” according to the 2009 study by Guaguère, É., & Prélaud, P.

Vitamin A Toxicity


Feeding excessive amounts of liver to cats leads to hypervitaminosis A, resulting in symptoms like lethargy and vomiting. The amount of liver consumed by cats is strictly regulated to avoid toxicity. Monitor liver intake a few times a week, opt for small portions, and consult with a veterinarian before making changes to the cat's diet to prevent vitamin A toxicity.


“Excessive intake of vitamin A in cats can cause liver fibrosis and should be considered in the differential diagnosis of chronic liver disease,” according to the 2014 study of Guerra, J., Daniel, A., Aloia, T., Siqueira, A., Fukushima, A., Simões, D., Reche-Júior, A., & Cogliati, B.

Contamination


Contamination of organ meats poses significant health risks to cats. Pet owners should prioritize sourcing organ meats from trusted local farms or suppliers known for their strict health and safety standards.

 

“Feeding raw meat-based diets to cats may pose health risks to both animals and owners, with potential zoonotic implications,” according to the 2017 study by Giacometti, F., Magarotto, J., Serraino, A., & Piva, S.

Proper storage, minimal exposure to air, and thorough cooking are essential. By following these practices, cat owners reduce the risk of contamination and ensure their cats receive safe, nutritious organ meats.
