Cat Food Allergies and Intolerances
Before delving into any further details, let’s get started with the basics.
Cat food allergies and intolerances are usually caused by a reaction your cat has to a particular ingredient – usually a protein. There are usually two types of adverse reactions – those that involve the immune system and are also known as food allergies, and those that occur within an immune component and are also known as food intolerances.
Regardless of which allergy your cat has, these allergies may last throughout their entire lifespan so it’s important to permanently remove them from your cat’s food.
What Causes Cat Food Allergies and Intolerances?
The usual culprit is the protein source (usually meat), in your cat’s food.
Also, just because your cat doesn’t have an allergic response now it doesn’t mean that they won’t have one in the future. It can take months or years before your cat even develops an allergic response to a particular food.
How Do I know If My Cat Has Food Allergies or Intolerances?
You’ll notice the following signs:
- Vomiting or diarrhea
- Hair loss or frequent scratching
- Serious ear problems
- Skin that’s inflamed and red
- Coughing, wheezing, and sneezing
What Are The Ingredients In Cat Food That Cause Allergies?
Some of the ingredients that could be causing these allergies include:
- Food dyes
- Meat and grain meals
- Corn and wheat gluten
- Rendered fat
- Butylated Hydroxyanisole (BHA)
- Butylated Hydroxytoluene (BHT)
- Propylene Glycol (PG)
Unfortunately, almost all of the commercially available cat food is considered to be feed-grade instead of human-grade.
These feed-grade ingredients are of lower-quality than human-grade food. An example would be meat and grain ‘meals’ containing by-products of dead animals from farms, ranches and other facilities along with fats, and other food waste from restaurants and stores.
As a side note, other food items that you shouldn’t serve your cat include:
- Onions and garlic
- Raw eggs
- Chocolate
- Raw meat and bones
- Alcohol and raw dough
- Dairy products
- Grapes and raisins
- Dog food
- Any other scraps
Finding The Best Hypoallergenic Cat Food

If you’re not sure where to start when it comes to figuring out what food is best for your cat, you should consult with a veterinarian. They’ll help answer some of your queries such as:
- Are there any foods you should avoid giving your cat because of their allergies?
- How does human food affect a cat’s health?
- Any special nutritional concerns that’s needed for your cat
- How often and how much should you be feeding the recommended food to your cat
- What treats you can feed your cat
- How quickly will you see signs of improvement
- Provide you with written instructions on food allergies for your cat
- If you need a follow-up appointment
You can also ask questions pertaining to your cat’s breed. Some examples include:
- What is the best weight for the breed you’re raising?
- What foods is this breed usually allergic to?
- What can you do to boost their immune system?
By having answers to the questions above, you’ll have a better idea of your cat’s physical health and know what parts of their body need strengthening.
