By-products: Explained

Definition of the Association of American Feed Control Officials (AAFCO)

Meat by-products is the non-rendered, clean parts, other than meat, derived from slaughtered mammals. It includes, but is not limited to, lungs, spleen, kidneys, brain, livers, blood, bone, partially de-fatted low temperature fatty tissue, and stomachs and intestines freed of their contents. It does not include hair, horns, teeth and hoofs. It shall be suitable for use in animal feed. If it bears a name descriptive of its kind, it must correspond thereto.

Poultry By-Products must consist of non-rendered clean parts of carcasses of slaughtered poultry such as heads, feet, viscera, free from fecal content and foreign matter except in such trace amounts as might occur unavoidably in good factory practice. If the product bears a name descriptive of its kind, it must correspond thereto.

On the other hand, the term “meal” often added to those meat or poultry by-products simply signifies that it is the same thing but in rendered form = elimination of water and fat to obtain a concentrated mix of protein and minerals (some kind of powder).

Theory VS Reality: Are meat by products bad for your cats ?

Theory: by-products are perfectly fine for your cat

In theory then, it seems that those by-products can be very useful for our fluffy friends (as long as it is not the only meat related ingredient in the food you choose).

For example, having bones in your cat’s meal is a good thing as it provides him with calcium and phosphorus. A bone is a bone, whether it’s from chicken feet or chicken wings it is nutritionally-speaking the same!

Organs like liver, spleen, kidneys or heart all contain great nutrients for your cat. Even intestines! From the definition, they are supposed to be cleaned, so they should not contain any kind of feces anymore. (By the way in France, intestines are a real delicacy for the food gourmet, so you see that even for us humans, those “weird” foods aren’t that bad after all).

In reality: the difficulty to evaluate the quality

It is extremely difficult to know the quality of the products used by the manufacturer of your cat’s food. How do you know for sure that the by-product is a healthy mix of healthy organs and bones and not just 95% of old chicken feet ?

The real question is simply to know the origin of the animal from which the meat/by-product comes from:

  • How was he fed ?
  • How was he treated ?
  • Is it free of contaminants ?
  • How was it preserved ?

If you can answer those questions, you will be able to evaluate the quality of the meat by-product you are feeding your cat!

How to really evaluate the quality of a meat by-product ?

The sad news here is that it is almost impossible to evaluate this quality by only reading the label on your cat’s food. You could ask the manufacturer to clarify this point but you might be waiting for quite a long time. (However if you do and get lucky, please update us so we can give more information to our readers!)

The only “easy” option you have is to choose a food made by a reputable manufacturer, evaluate expert’s advice on that specific food (long time users, vets…) and in the end, evaluate your little friend’s response to that food:

  • Level of excitement when you give him the food (if he barely touches it, that should tell you something)
  • Normal gastrointestinal function (solid stools bro! and no vomiting!)
  • Healthy skin and coat
  • Proper energy level (also based on your cat’s breed, age, health)

Our advice on meat by-products

When your little hunter makes a kill in the wild, what do you think he eats ? Yep, you guessed that right! In the nature there is no such thing as a cat eating in a nice bowl and dining very carefully and tasting the best part of the animal he just butchered. He just “goes for it” and eats whatever will bring him the proteins, nutriments and anything he needs to remain healthy!

Cats are for the most part strong animals, with a strong body designed to hunt and resist to roughness of mother nature. Although you have a right to be picky about his food, you should also understand that there is no need to drag your decision forever about finding the right food.

At Fluffy Kitty, we do not believe in the alarmist conspiracy theories about the pet industry. We know each and every pet manufacturer out there wants to make money but we also know that some of them actually care about the products that they make. If they cause problems to your cat, how likely is it that you are going to buy their product again ? Moreover, those same manufacturers noticed that people became more and more educated about the importance of good nutrition for cats, so they are slowly starting to produce better foods at a higher quality.

Several brands developed products around a healthier formula with healthier and more natural ingredients. Some examples of superb premium-quality cat food brands include: Taste of the Wild, Blue Buffalo, and Purina One are amongst the top quality manufacturers and we trust those companies to provide the best food quality possible for your cat (we are not sponsored, this is our honest opinion). They simply provide real meat ingredients, no corn, wheat, soy, or other low-quality filler ingredients and provide a variety of healthy veggies, fruits, and super antioxidants to super charge your cats food.  You can tell that these brands go above and beyond compared to their low-quality competitors such as Meow Mix (which does not provide all this goodness).

Are meat by products dangerous for your cats: Final thoughts

This is not to say that you should completely avoid meat by-products. Just make sure that they are secondary or third in your cat’s diet and that “real meat” is the actual main ingredient in your cat’s food.

Our preference for meat over by-products is simply cultural, as anyone who has traveled extensively can attest to. I guess that’s the reason why it is a common misconception that all meat by-products are terrible for your cat. We agree with you, it is very difficult to read pet food labels but it is also possible to find a great product that respects your cat’s needs.

Alarmist conspiracy theories claim that most, if not all brands in the pet food industry want to sell crappy products at the highest price hidden behind a good marketing. There will always be bad guys out there producing bad products but I believe it is possible to identify and avoid them.

When you have the right information, you are actually free to decide to choose the best for your pet.

Finally, if you do not trust the products available out there, you could also consider making your own cat food! It will take more time but if you want what is best for your cat, this will be a must for your feline friends.
