What is Hypoallergenic Cat Food?

Hypoallergenic diets for cats are composed of hydrolyzed proteins. In this kind of a diet, animaproteins are broken down into extremely small pieces. When your cat consumes hypoallergenic food, its body doesn’t recognize the protein, and the food gets digested without upsetting the stomach. Hydrolyzed protein diets are less allergenic, which is why these are called hypoallergenic diets. Hypoallergenic cat food does not contain beef, dairy, poultry, or wheat.

How to Select Cat Food For Allergies?

It is crucial to select an allergy-free cat food carefully. Here are some factors to consider while purchasing hypoallergenic cat food for cats with food allergies.

Protein Source:

Most cat allergies are linked with common animal protein sources. High protein cat foods can thus be problematic sometimes. That’s why it is critical to find hypoallergenic food with a neutral protein source. Such as you can opt for cod, salmon, whitefish, and duck. You may also switch to a novel protein source that your pet hasn’t tried before.

Limited ingredients:

Make sure to start with feeding your feline hypoallergenic food that contains minimal ingredients. All hypoallergenic foods aren’t limited-ingredient foods. Therefore, you must always check the label and make sure that the food is free of common allergens  like beef, poultry, fish, dairy products, or grains, and has a limited number of ingredients. A limited-ingredients diet is beneficial if you aren’t sure what allergy is triggering a reaction.

Dry vs. Wet Hypoallergenic Cat Food

You will find hypoallergenic cat foods in both wet and dry options. Dry cat foods, typically, are a cost-effective option in comparison to wet foods. However, sometimes, your feline may find wet food a lot tastier. This is especially true for fussy or selective eaters. Wet food is a better option if your cat’s water availability is limited because it allows it to consume more liquids, which will aid the digestion process.

Moreover, most cats with food intolerances or allergies are old and may have various other health issues. For such cats, dry cat food in hard kibble form will be tough on their teeth, and they will find it hard to swallow.

Similarly, some cats may not find wet, canned food too appealing because of it’s texture. When this is the case, dry food might be a better alternative. Therefore, when buying hypoallergenic cat food, you must think about your cat as an individual with individual taste and preferences. It would be best if you coul incorporate both types of food.

Often you can find really good cat food also in forms of broths which are super nutritious and low in any fillers. Especially if you buy human grade cat food made in the USA, you can only expect the best for your cat.

Most Common Food Allergies in Cats:

Beef, fish, poultry, and dairy products are common foods that trigger allergies among cats. There may be other allergens that are impacting your feline’s health. To diagnose the right cause of the allergy, always consult your veterinarian.

What Causes Common Cat Food Allergies?

Cats may develop food allergies at any time throughout their life. Research reveals that genetic predisposition plays a fundamental role in triggering food allergies. Additionally, allergies may be linked with atopy, which refers to inhalant allergies. Some cats are allergic to both environmental allergens and food ingredients.

A change in your cat’s regular diet doesn’t need to contribute to food allergy development. Around 70% of pets develop allergies because of food ingredients they have been consuming for a long time, even more than two years. It takes several exposures to a particular food or ingredient to produce an allergic reaction. You may find it surprising, but grains can also trigger food allergies. And many cats are allergic to certain animal proteins.

Food Allergies in Cats Symptoms

If your cat has a food allergy, it will start having some specific symptoms. These include:

  • Skin problems like itchy or pruritic skin particularly around face, paws, or ears
  • Digestive issues such as chronic diarrhea or vomiting
  • Hair loss (Is different from shedding – find best cat food for shedding here)
  • Skin inflammation
  • Runny or red eyes
  • Flatulence
  • Coughing, or sneezing 
  • Foul skin odor
  • Papules or red bumps
  • Self-inflicted trauma mainly caused by recurrently occurring itching
  • Severe scaling
  • Ear infection

Sometimes bad skin and coat problems will be caused by allergies, while in other it will only be a matter of nutrition. This and other ambiguities when it comes to determining the underlying conditions are best resolved by visiting a vet. In case bad nutrition is affecting skin and coat health – we have prepared a list of cat foods for healthy fur.

Cat Food for Itchy Skin – Is Hypoallergenic Diet Suitable?

Cats with food allergies often experience year-round chronic itching and skin inflammation that particularly affects the ears, face, groin, belly, armpit, and paws/legs of the feline. The itchiness is so severe that they often overgroom themselves. This can result in abrasion or wounds. Some cats may experience hair loss. Also, affected cats often develop recurrent ears and skin infections. 

The first thing you need to do if you feel that your cat is allergic to something is visiting your veterinarian. The vet will run a series of complex tests to discover which carbohydrate or protein makes your feline sick. After appropriate testing and screening, the vet will diagnose a suitable mode of treatment. 

If you want to treat the allergy through diet, a hypoallergenic diet for cats with food allergies or limited-ingredients cat foods may be beneficial. Since these foods don’t contain many ingredients, so the risk of allergy is minimal. The hypoallergenic diet is highly digestible and formulated after considering the dietary needs of allergy-prone feline. Though no food can be completely allergy-free cat food as cats have varying nutritional needs. But, hypoallergenic food oftenworks for cats with chronic skin allergies . 

Food allergies in cats treatment

If the current diet is not suiting your cat, try something different. In this regard, hypoallergenic, single protein cat food can be a good way to start. However, always  consult a vet before adding anything new in your pet’s daily diet or switching to a whole new dietary regimen.

A less complicated method of treating food allergies in cats is to feed them something they haven’t eaten before. For instance, if your cat’s regular diet involves a lot of fish or chicken, try feeding it fish-free cat food or poultry free cat food or other type of limited ingredient cat food. If you notice that the symptoms have cleared up, then this means something in its previous food regimen was causing the allergic reaction.

What is novel protein cat food?

Novel protein cat food contains unique or novel ingredients. These ingredients aren’t commonly a part of pet food or pet diet, such as duck or pork are novel proteins and sweet potato is a novel carbohydrate.

Novel protein diet is different from conventional cat food because it contains a less common and less-mainstream source of protein. Usually, best cat foods contain beef or chicken as the primary protein source. These are mainstream proteins, and continuous exposure to similar protein sources can trigger allergic reactions in some cats. On the other hand, novel protein diets contain proteins from unusual sources such as rabbit, kangaroo, bison, or elk. Since the pet hasn’t been introduced to these sources of protein previously, it is highly unlikely that they would experience an allergic reaction.

The idea behind introducing novel protein cat food in your feline’s diet is to allow them to eat food they haven’t tried before. As mentioned above, most cats develop food allergies from ingredients they have been consuming for a long time. 

For sensitive pets, novel ingredients prove very useful since the cat hasn’t encountered them before. If the cat is exposed to chicken or beef a lot, feeding your cat something rare like a rabbit would be beneficial.
