Cat food allergy symptoms in cats

If your cat has food allergies, you may notice the following signs:

Vomiting or diarrhea
Loss of appetite
Soft stools
Itchy and swollen skin


Food allergies are extremely dangerous, can cause life-threatening reactions, not just vomiting or diarrhea, pet parents should find a solution in a timely manner.

15% -20% of cats are allergic to some kind of food. The veterinary advises that pet undergoes an intradermal test(IDAT) or a blood test or serological test to identify allergens which can be avoided.

Pet testing is an accurate way to deal with food allergies, but it does take a lot of time and money. A simpler and more effective way is that if we find that the cat has allergies, we can choose "hypoallergenic and healthy cat food".

When choosing hypoallergenic cat food, pet owners often have the following questions

- Which foods are most likely to cause an allergic reaction?
- How do I identify allergens from the ingredients list?
- Hypoallergenic cat food maybe limit the choice of ingredients, will it lead to a lack of proper nutrition?

My name is Patricia, my good boy Caudill is a British Shorthair, which is the brand ambassador of NatureBridge.

About "hypoallergenic cat food", I interviewed a number of vets, other experienced pet parents, and based on my own experience, I would like to share with you how to choose a "hypoallergenic and healthy" cat food.

8 Tips for Choosing A Hypoallergenic Cat Food For Your Cat

For cats, the most common food allergens are beef, lamb, dairy products and gluten-containing grains, which account for nearly 90 percent of food allergy symptoms and cases.

  • 1. Avoid red meat such as beef, lamb and pork

    Red meat such as beef, lamb and pork are considered to be the ingredient with the highest proportion of allergies in cats. According to a survey of adverse food reactions (AFR) in cats, based on 65 published AFR-related food ingredients conducted in food challenge tests, red meat (beef/pork/lamb) allergies accounted for the highest proportion of allergic reactions (66/238, 27.7%).[1]
    It contains galactose-alpha-1,3-galactose in the cell membrane of red meat such as cattle, sheep and pigs, which is the main cause of cat allergies. Allergic reactions of cats to these meats are mostly reflected on the skin and stomach, manifested as itchy, swollen skin, rash, diarrhea, nausea and vomiting.

    Did you know that Cattle and sheep are not only easy to cause cat allergies, but also cause "allergies" in the earth

    This is because the feeding process consumes a lot of resources and produces more greenhouse gases. The following data comes from the report " LIVESTOCK'S LONG SHADOW Environmental Issues and Options" by the Food and Agriculture Organization 锛團AO锛塠2]
    路 The methane produced by cattle and sheep animal husbandry contributes 1/5 of the global greenhouse effect;
    路 Methane has 28 times the greenhouse effect of carbon dioxide;
    路 15,415 liters of water per kilogram for beef and 8,763 liters of lamb;
    路 Animal husbandry, mainly cattle, sheep and pigs, consumes 70% of the earth's water resources every year, while human drinking water only accounts for 10%;

  • 2. Chicken is the best choice, why?

    路 The galactose-alpha-1,3-galactose that causes cats in meat is mainly present in the cell membranes of mammals, while chickens are birds, so the cat allergy caused by chicken is the least of all meats;
    路 The nutrition provided by chicken and beef is equivalent, their protein is about 20%, and the amino acid composition is basically the same;
    路 Chicken is easier to digest because it contains more soft connective tissue than beef;
    路 Chicken fat contains four times more polyunsaturated fatty acids and linoleic acid (omega-6) than beef, which are important for preventing obesity in cats, reducing the risk of cardiovascular disease and promoting brain function. [12]
    路 Chicken has three times the calcium content of beef, which is more helpful for cats' bone health. [13]

    Chicken is also a better choice for our planet.

    The following data comes from the report " LIVESTOCK'S LONG SHADOW Environmental Issues and Options" by the Food and Agriculture Organization (FAO) of the United Nations [1]
    路 Save 11,000 liters of water per kilogram of chicken compared to beef;
    路 The greenhouse gases produced by cattle and sheep husbandry are about 5 times that of raising chickens;
    路 Each kilogram of beef requires 13 kilograms of feed, and each kilogram of chicken saves 60% of the feed compared to beef.

  • 3. Adequate amount of fish

    The benefits of adding fish to pet food:

    Fish are not mammals, do not have galactose-alpha-1,3-galactose in cell membranes, and are less allergenic than cattle, sheep and pork;
    The cat's sense of smell is 30 times that of humans, and the fresh smell of fish can increase the cat's appetite;
    Cat night vision needs to be supplemented with a lot of taurine, and the content of taurine in fish is 10 times that of meat;

    It is not recommended to use fish as the main ingredient of pet food:

    Deficiency of thiamine, vitamin K, and vitamin E in fish may lead to ataxia, metabolic disorders, and yellow lipemia in cats;
    The histamine acid in fish will turn into histamine after leaving the water, and excessive histamine may lead to allergies or even poisoning;
    Insufficient calcium and iron in fish can lead to mineral imbalance

    NatureBridge Beauty Series has chosen chicken and salmon as the main ingredients to provide cats with a hypoallergenic and high quality protein.

    Ingredients
    • 4. Avoid dairy products

      Some cats cannot drink milk because of lactose intolerance, which is the lack of lactase enzymes that degrade lactose;
      Each 100ml of milk contains about 3 grams of protein, including casein and whey protein. Both proteins have the potential to cause allergies;
      When a cat's immune system mistakes its normal intake of milk protein for an invading enemy, it triggers a cascade of immune responses against the "enemy," which can lead to vomiting, diarrhea, swollen skin, asthma and other symptoms.

    • 5. Avoid gluten-containing grains

      Many cats are allergic to gluten, not all grains.
      Gluten, also known as gluten protein, is not a plant that can be seen and touched. It is mainly composed of two proteins, alcoholic protein and gluten. It is stored in some grains. Barley, wheat, and oats contain gluten;
      Cats have relatively short intestines (especially the small intestine) and are not suitable for digesting gluten-containing grains;
      Grains such as rice and corn are gluten-free.

    • 6. Choose a gluten-free Cat Food

      Carbohydrates are essential ingredients for hypoallergenic dry cat food:
      As a supplement to meat, it can provide an equivalent source of energy for cats;
      It ensures that the various ingredients in the cat food are mixed and formed, so that the cat food particles remain in shape and are not easily broken; [7]
      It can supplement iron, and the iron content of hypoallergenic meat (chicken, fish) is lower than that of highly allergic beef;
      In the process of making dry cat food, the digestion and absorption rate of carbohydrates in cooked rice and corn can reach up to 100% [3,4,5]


      "Grain-free" 鈮 "No Carb" "Grain-free" dry cat food, is not "No Carb ", they usually use potato starch, tapioca starch and other raw materials to replace grains, these refined starches can not provide grains contain crude fiber and other nutrients, may reduce the nutritional value of food, at the same time, it may also make the content of carbon and water in pet food higher than meat.


      Therefore, when buying hypoallergenic cat food, you only need to pay attention to the "gluten-free" on the packaging, and the recipe uses rice and corn as gluten-free grains.

    • 馃審 Environmental Tips

      Although meat is a cat's habit, we can make it more environmentally friendly.

      Cats have a carnivorous nature, but over thousands of years of living with humans, domestic cats have evolved physiological adaptations for carbohydrate digestion and absorption [1,2]. In the process of making dry cat food, the digestion and absorption rate of carbohydrates in cooked rice and corn can reach up to 100% [3,4,5].


      For each hectare of land, 20 people can be fed by growing food, while only 2 people can be fed by raising cattle and sheep. The energy coefficient (density) of both protein and carbohydrates is 4.0kcal/g. So, supplementing meat with the right amount of carbs can provide the same amount of energy for cats, but save 10 times the land.

    Glute Free

    The intestinal of cat is very different from human, that is more likely to get allergy to gluten.

    Common symptoms for gluten intolerance are skin problems (itching and hair loss), vomiting, or diarrhea.
    The most serious condition is causing celiac disease. In this case, the pet will suffer from malnutrition and even poor growth.

    NatureBridge "Gluten Free" recipe replace the gluten ingredient with rice & pea, which avoid gluten from the very beginning.

    Glute Free Cat Food
    • 7. Avoid chemical food attractants

      In order to make the pet food produced by some pet food manufacturers look delicious, pet food manufacturers will turn their attention to compound flavors. As long as a small amount is added, the palatability (and sales) can be greatly improved, the nutrition is up to standard, and the cost is still low. The more common ones are as follows:

      路 Sodium pyrophosphate: Adding too much Sodium pyrophosphate will accelerate the oxidation of oil in pet food, which will lead to nutrient loss and deterioration, causing pets to get sick. When choosing pet food, you should pay attention to check whether the ingredient list contains acidifiers such as sodium phosphate. If so, try not to buy it, or eat less.

      路 Glycine:Glycine produces sweetness. It is a sweetener. It can also mask bitterness and improve the palatability of pet food. Excessive addition can cause diarrhea in pets, it is best not to eat or eat less.

      路 Putrescine:This gaseous substance is a preferred scent for cats... Pet food does add this gas to stimulate the appetite of cats and dogs, but because it's not an ingredient, it doesn't appear on the ingredient list.


      In addition to these chemically synthesized flavors, there are actually some natural " Appetite Stimulants " that do not appear in the name of obvious " food attractants " or "flavor enhancers", but they can significantly improve the palatability of pet food, and adding them is also good for health.

    • 8. Avoid artificial preservatives

      In order to prevent rapid oxidation of cat food after opening and improve the shelf life, most cat food contains preservatives, such as: 伪-tocopherol, acerbic acid, sodium ascorbate, calcium ascorbate, citric acid, etc.

      Artificial preservatives can also cause food allergies in cats, among which Butyl hydroxy anisole (BHA) and Dibutyl hydroxy toluene (BHT) can definitely cause cat discomfort. When preservatives are sensitized, cats will experience such as vomiting, diarrhea, dermatitis, itchy skin, hair loss, etc.

      Pet owners try to choose pet foods that use natural preservation methods.

    Eliminate allergy to artificial preservatives, and adopt nitrogen protection black technology

    NatureBridge has also mastered a patented preservation technology that does not use preservatives - nitrogen preservation.
    By filling with colorless, odorless and pollution-free, completely safe nitrogen, the oxygen in the food is driven away, thus isolating the oxidation reaction of pet food and locking in nutrition and deliciousness.
    Nitrogen also forms a "nitrogen seal". Equivalent to vacuuming, the physical method cuts off the oxidation reaction, the process is healthier, there is no artificial chemical synthesis component, and the use of antioxidants is reduced. It is the healthiest and most effective technology, and will not breed bacteria.


    In addition, it adopts a four-layer aluminum packaging design and is equipped with a secondary seal, which allows the Beauty pet food to retain more fresh-keeping nitrogen after opening, so that the product remains fresh, healthy and crispy for a longer time.
