When shopping for cat food you may already understand the importance of checking the ingredients list. The ingredients list on pet food products is organized in descending order by volume which means that the ingredients at the top of list are present in the highest quantity (volume). You don’t have to be a pet food expert to understand, then, that it is best to see high-quality, natural ingredients in the first few slots on the pet food ingredients list. What many cat owners fail to realize is that the ingredients list on their pet food package does not always tell the whole story.

Just like human food products, pet food products can contain GMO ingredients and the package will not necessarily make that clear to the consumer. You may already know about the dangers of by-products and artificial ingredients, but GMO ingredients can be hiding in plain sight on the pet food package. In order to ensure that you choose a healthy, high-quality pet food for your cat you need to learn what GMO ingredients are, how to identify them, and how to choose a non-GMO cat food.

What Exactly Does GMO Mean?

The acronym GMO stands for “Genetically Modified Organism”. While this term may bring to mind pictures of wild science experiments or alien life forms, it simply refers to organisms and crops that have been altered at the DNA level to boost specific qualities. For example, genetically modified organisms can be altered to make them more resistant to pests or to help them thrive in certain environmental conditions (such as particularly dry areas). Genetic modifications can even help to increase the nutritional value of the food.

While the anti-GMO craze has reached its peak in recent years, GMO crops have been commercially sold since the 1990s. Genetic modification has been focused primarily on cash crops like soy, corn, and wheat but more and more GMO ingredients have started to work their way onto pet store and grocery store shelves. With the increasing use of GMO ingredients in human and pet foods, there has been a great deal of debate regarding the health and safety of these products in recent years.

There is a very large anti-GMO faction in the United States, though the FDA has yet to ban or even significantly limit the use of these product. In fact, there is yet to be a conclusive scientific study that proves the danger of GMO ingredients for humans or pets. In fact, the FDA doesn’t even require food manufacturers to identify GMOs on their product labels – some of the foods you eat most often probably contain GMOs and the same could be true for your pet.

What GMO Ingredients Do I Need to Watch For?

There have been many studies regarding the health effects of consuming GMO ingredients. Unfortunately, the results of these studies can easily be manipulated to suggest a correlation that is not necessarily there. If you do some research of your own, you will find that many of the studies that delve into the effects of GMO ingredients show that these ingredients are completely safe for human consumption. In fact, many of the studies that do suggest a negative correlation between GMOs and human health are flawed or they are not true scientific studies.

While there is no conclusive evidence regarding any negative long-term effects of GMO ingredients (for pets or people), it is worth noting that many GMO ingredients are ingredients that are bad for pets anyway. According to the Natural Society, the top 10 GMO foods are:

  • Corn
  • Soy
  • Sugar
  • Aspartame
  • Papaya
  • Canola
  • Cotton
  • Dairy
  • Zucchini
  • Yellow Squash

If you take a look at this list you will notice several foods that are on the “No” list for cat food – this includes corn, soy, sugar, aspartame, canola, and dairy. Cotton is not a food product, so it can be excluded – this means that the only healthy GMO ingredients your cat might end up eating include papaya, zucchini, and yellow squash. The Global Healing Center has a longer, more in-depth list of GMO ingredients which also include things like high fructose corn syrup, corn starch, beef, and vegetable oil.

While the ingredients listed above are often genetically modified, you still need to remember that there is no conclusive evidence pointing toward negative long-term effects correlated to GMO consumption. It is important to remember that genetic modification can be accomplished in a variety of ways. There are some chemical methods for modifying an organism’s genetics, but selective breeding is a form of genetic modification anyway. By choosing to breed organisms with certain genetic traits you can essentially design an organism with whatever qualities you want. For example, by breeding cows that have higher rates of milk production together you can create a breed of cow that produces more milk than other bovine breeds.

When it comes to determining whether GMO ingredients are bad or go, they must be evaluated on a case by case basis – there is no definitive Yes or No to the question “Are GMO ingredients dangerous”. Many studies have revealed that the risks associated with genetically modified foods are no greater than the risks associated with foods created through selective breeding. In fact, most animal studies show that GMOs are safe for consumption and there is no conclusive evidence to show that GMOs cause harm to humans. Still, it is your prerogative to choose non-GMO cat food for your pet, if you so desire.

How Can I Find Non-GMO Cat Food?

As it has already been mentioned, pet food manufacturers are not required to identify any GMO ingredients that they use in their products. If you want to know whether a product uses GMOs, you will need to be familiar with the foods that are most frequently subject to genetic modifications and you may need to do some research about the individual brand to find out where they get their ingredients. Just because a pet food is labeled “natural” does not necessarily mean that it is not a GMO cat food – many GMO ingredients are considered natural because they have not been processed.

If you want to find a non-GMO cat food for your cat, you should probably stick to organic pet foods. Some pet food manufacturers will label their products non-GMO, but most do not make this distinction. The only guaranteed way to find a non-GMO product without having to do a lot of background research is to choose a product made with organic ingredients. Look for a product that has the “Certified USDA Organic” label on it. Do not assume that a product labeled as “holistic” is organic, either – the use of this term is not closely regulated so it may be nothing more than a marketing gimmick.

Tips for Choosing a High-Quality Cat Food

In addition to looking for an organic cat food, you also need to know how to read the ingredients list on the package to determine the quality of the product. The first thing you need to look for on a pet food label is the AAFCO statement of nutritional adequacy. The American Association of Feed Control Officials (AAFCO) is responsible for regulating the manufacture and sale of pet food products and animal feed. Pet foods are not as closely regulated by AAFCO as human foods are by the FDA, but there are certain restrictions and regulations in place. For example, in order for a pet food to be labeled as “complete and balanced” it must meet the requirements of certain nutrient profiles established by AAFCO.

The nutrient profiles established by AAFCO are based on the minimum nutritional requirements of pets in certain life stages. If a pet food product meets these minimum requirements, the package will carry a statement such as the following: “[Product Name] is formulated to meet the nutritional levels established by the AAFCO Cat Food Nutrient Profiles”. If the cat food you are looking at carries this statement you will know that it is designed for use as a staple diet. What you need to realize, however, is that the AAFCO statement of nutritional adequacy is not necessarily an indication of quality – you can meet the minimum nutritional requirements for cats by using low-quality ingredients. This is why you need to review two other important parts of the pet food label – the Guaranteed Analysis and the Ingredients List.

The Guaranteed Analysis for a cat food product simply shows the minimum values for crude protein, crude fat, crude fiber and moisture as percentages. This is a valuable analysis to have if you are trying to compare two different cat food products. Ideally, the protein content should be very high and the fat content should be moderate. The lower the fiber content the better, since that is correlated to the amount of carbohydrate in the product. It is important to remember, however, that the guaranteed analysis provides a total percentage of protein, fat, and fiber – it doesn’t tell you where these nutrients come from. Protein can come from both animal and plant sources, for example, so you still need to check the ingredients list to determine the quality of the product.

As you have already learned, the ingredients list for pet food products is organized in descending order by volume. The ingredients at the top of the list are present in the highest volume while those at the bottom of the list may only be included in trace amounts. This being the case, you want to see high-quality sources of animal protein, healthy fats, and digestible carbohydrates near the beginning of the list. The first ingredient should always be a source of animal protein – something like fresh meat, poultry, or fish. Meat meals are also a valuable inclusion in pet foods because they have been cooked down prior to their inclusion which means that their volume will not change much when the whole product is cooked – fresh meats contain up to 80% moisture so their volume will decrease significantly during cooking.

In addition to checking for high-quality proteins at the top of the ingredients list you should also pay attention to the carbohydrates used in the product. Cats have a very limited ability to digest plant matter so any carbohydrates included need to be easily digestible for cats – this includes things like brown rice, whole grain oats, sweet potatoes, peas, and tapioca. You will notice that things like corn, wheat and soy are not included – not only are these frequently GMO ingredients but they are low in nutritional value for cats and difficult to digest. Healthy fats like chicken fat, salmon oil, or other fish oils are a valuable addition to high-quality cat foods, as are chelated minerals and dried fermentation products (included as probiotics). Avoid cat food products made with by-products, artificial ingredients, and low-quality fillers.

If you are concerned about feeding your cat GMO cat food, your best bet is to choose an organic cat food product.

Castor & Pollux Organix

The Castor & Pollux pet food company is one of the few organic pet food brands in existence. According to the brand website, the Organix line of pet food products is the most complete line of USDA-certified organic food for cats and dogs. Not only are Castor & Pollux’s products made with certified-USDA organic ingredients, but they also make use of Non-GMO Verified ingredients as well. The Castor & Pollux Company was founded more than twenty years ago by husband and wife pair Brian Connolly and Shelly Guntun who sought to produce a high-quality pet food product for their dog, Joey. As organic and natural ingredients became increasingly more available, the pair saw an opportunity to take advantage of it with their pet food products. And thus the Castor & Pollux Natural PetWorks company was born.

The Castor & Pollux Company offers two lines of organic cat food products – Organix and Organix Grain-Free. Within the Organix line of products there is one dry food recipe, four wet food recipes, and one organic cat treat.
