Best Limited Ingredient Cat Food : Information & Analysis
Limited ingredient cat food is similar to hypoallergenic cat food. These foods are usually fed to cats that have food allergies or food intolerances. They typically have a single protein source and a single carb source – ideally something that your cat hasn’t eaten previously. The idea is to change your cat’s diet to something that won’t trigger his allergy or food intolerance.
Common Cat Food Allergens
For cats, the most common allergens are:
- Dairy products
- Wheat gluten
These are also some of the most common proteins in typical cat foods, which is no accident. Cats, or any animals, have to be exposed to foods more than once before there can be an allergic response. It’s believed that the more common proteins are in foods, the more likely they are to lead to allergic reactions in the general population. So, if pet food companies suddenly begin using rabbit as a cat food ingredient, eventually a lot of cats will develop allergies to rabbit. These ingredients aren’t “bad” ingredients, they can simply be triggers for some cats. Some cats can have triggers to uncommon allergens.

Cats with a food allergy can have some typical signs of an allergic reaction such as itching, loss of hair, lots of scratching, and miliary dermatitis (featuring skin lesions). It can be difficult to tell if your cat has a food allergy or some other kind of allergy or skin problem, but food allergies can occur year-round, and their itchy skin probably won’t respond to steroids.
A food intolerance is a little different. A food intolerance usually affects the cat’s gastrointestinal tract instead of causing itching and scratching or hair loss. The cat may have vomiting or diarrhea because something in his food is irritating his G.I. tract. Even if he enjoys his food when eating it, the food may cause an irritation during digestion. It’s a little like someone with a sensitive stomach eating a spicy food or fried foods and paying the price afterwards.
Diagnosing food allergies
If your cat is showing signs of a food allergy, it’s best to have your vet confirm your suspicions. There are a number of illnesses that can exhibit the same signs such as other kinds of allergies, intestinal parasites, certain infections, and some skin problems. Before you spend a lot of money changing cat foods, it’s wise to have your vet check your cat first. Your vet can usually determine if your cat has a food allergy fairly quickly. However, it may take a little longer to figure out what your cat is allergic to.
The proven way to determine what your cat is allergic to is by putting him on an elimination diet and going through a food trial with him. This means that you will feed him a food that he has never eaten before for approximately 12 weeks. The food should consist of one protein and one carb. You and your vet can confer to choose the food for your cat. An example might be a food that contains venison and green peas. Several companies make these food in prescription formulas and there are some available commercially. These are “limited ingredient diets.” In some cases, if the cat is allergic to a lot of common foods, there are some prescription foods using hydrolyzed proteins. This means that the protein used in the food has been broken down into such small molecules that the cat’s body will not be able to recognize the protein source so there can’t be an allergic reaction. If the cat requires a very novel protein, some people make homemade diets for their cat during the food trials, under the veterinarian’s advice. The important thing is that the cat does not eat anything other than the single protein and carb that have been chosen for the food trial. The purpose is to rule out everything else in the cat’s diet that could be causing the allergy.
Once the cat has finished the 12 week elimination diet – and he has, hopefully, not had any allergic reactions – you and your vet can begin to add, one ingredient at a time, things to his diet that were previously in his food. When he has an allergic reaction to one of these ingredients, you will be able to isolate the item that your cat is allergic to and avoid that ingredient in the future. Your cat may be allergic to more than one ingredient, so it’s a good idea to continue testing ingredients until you have checked all of the possible allergens in your cat’s old food.
This is how you can really find out what your cat is allergic to. Many people do not go to this time and trouble to determine their cat’s allergies. If their cat has an allergic reaction while eating a food, they will simply make assumptions about some of the ingredients in the food and start buying different cat foods, hoping they are buying a food that won’t trigger a reaction. You can certainly follow this method but it’s not always successful. Many times you will end up buying a lot of expensive cat foods that will also cause your cat to have an allergic reaction. Or, you might feed a cat food that doesn’t produce a reaction and attribute the your cat’s allergy to the wrong ingredient. It can be a very expensive way of trying to figure out your cat’s allergy without getting a definite answer.
When you have determined the ingredient(s) that your cat is allergic to, you can choose the appropriate limited ingredient or hypoallergenic cat food for your cat. Depending on the allergens that trigger your cat’s allergy or food intolerance, you may need to buy a prescription cat food or you can buy a food that is commercially available. Prescription diets may sometimes seem to have ingredients that are not as popular today, including some grains or even by-products, but they are usually made under very exacting standards so you can be certain that these foods do not contain any ingredients (or allergens) that are not supposed to be in the food. Commercial limited ingredient diets may include very good quality ingredients but they may not be made to prescription standards. You may not be 100 percent certain that the food doesn’t contain a hint of some food that your cat should not eat, for example.
Dos and Don’ts
Whether you are following an elimination diet from your vet or trying to figure out your cat’s allergy on your own, there are some dos and don’ts you should keep in mind. You need to stick to the diet you have chosen for your cat and don’t feed him things that aren’t on the diet. Any of these other things could also cause an allergic reaction.
When your cat is on a food trial, do not give him:
- Flavored medications supplements
- Flavored plastic toys
- Any type of food when giving medications
Any of these things could cause an allergic reaction that might wrongly be attributed to your cat’s food.

The Basics line of products features grain-free recipes made with a limited number of ingredients to help reduce food allergies and sensitivities.

Best Prescription Limited Ingredient Cat Foods
Some of the prescription cat foods that would be considered “limited ingredient diets” include:
- z/d® Feline Low Sensitivity – Dry – Hill’s Pet Nutrition
- z/d® Feline ULTRA – Canned – Hill’s Pet Nutrition
- Royal Canin Veterinary Diet Hypoallergenic Hydrolyzed Protein HP (dry)
- Royal Canin Selected Protein (dry and canned)
- Purina® Pro Plan® Veterinary Diets HA Hydrolyzed™ Feline Formula
If your cat needs one of these diets, you will have to talk to your vet about getting a prescription. They are pricey but they are usually very good. We know that the ingredient lists look awful. In this case you just can’t worry about it. These are prescription diets and when you need them, you really need them.
These are just a sample of the limited ingredient foods available. Although many brands claim to have “limited ingredient” foods, it’s important to read the label to see what’s really in the food. The cat food may have a single source of animal protein, for example, but it may use peas and other plant proteins that would not agree with your cat’s digestion, especially if he has a sensitive stomach. Some limited ingredient foods use added natural flavors which, in pet food terms, can mean monosodium glutamate (MSG) or other other additives. (The FDA considers a lot of things “natural.”) Although the main ingredients of the food may look good, such as turkey and tapioca, it’s important to consider all of the ingredients and how they might affect your cat’s digestive system. Sometimes you just have to keep looking at foods until you find one that is safe for your cat’s sensitive system.
How many other cat foods are out there that contain this menadoine.
Vitamin K ?
How dangerous is this ?
I don’t agree with this because the most common proteins in cat food are chicken, turkey and fish. It’s hard to find a cat food without those ingredients.
