What Should You Feed Your Cat?
Cats are carnivores. That means they need a source of animal protein in their diets to keep them healthy.
Cats will never do well on a vegetarian or vegan diet. Meat is essential in your cat’s diet because he needs the nutrients it contains.
Although cats love fish, it’s not an acceptable food for an exclusive daily diet.
That’s because fish contains very high levels of fatty acids, and overeating can cause vitamin E deficiency in cats.
Cats also need a carbohydrate and fat in their diet. But feeding cats a saucer of milk or cream is not a good idea.
That’s because many cats are lactose intolerant, and feeding them dairy products can make them sick.
Most commercially available cat foods are balanced to contain everything your cat needs to stay in good health.
However, sometimes cats can develop a sudden allergy or intolerance to something in their diet.
This is even though they may have enjoyed the same cat food for years with no ill effects.
What Foods Cause Allergies in Cats?
Several items commonly cause food allergies in cats, including:
- gluten
- dairy products
- seafood
- soy
- corn
- beef
- lamb.
Interestingly, many of these foods cause severe allergic reactions in humans too.
And a casual glance in that cat food aisle confirms these proteins are inside.
Your cat may have eaten the same brand of cat food for years without experiencing any problems.
So, why would your cat suddenly become allergic to his favorite cat food?
All animals must typically be exposed to foods on many occasions before they develop an allergic response.
The more common that proteins are in cat foods, the more likely there will be allergic reactions among cats who are fed these products regularly.
The ingredients used in commercial cat foods are not generally considered to be harmful.
They can simply be allergy triggers in some cats.
How Can You Tell If Your Cat Has a Food Allergy?
A food allergy often causes typical allergic reaction symptoms, including:
- hair loss
- scratching
- itchy skin
- miliary dermatitis.
Diagnosis of a food allergy can be tricky, but food allergies can emerge at any time of year.
The itchiness caused usually does not respond to steroid treatment.
For example, it’s straightforward to blame fleas for a scratchy, itchy cat. It’s also easier to blame fleas than cat food.
What Is a Food Intolerance?
Food intolerance is not the same condition as a food allergy. Food intolerance usually upsets the cat’s digestive system.
Rather than itching, scratching and hair loss, the cat has diarrhea or vomits because something he has eaten is irritating his gastrointestinal tract.
The cat may thoroughly enjoy what he’s eating; it’s only as the food moves through his digestive system that problems start.
How Are Food Allergies Diagnosed?
If you suspect that something in your cat’s food is causing him problems, you should consult your vet right away.
That’s because other conditions such as infection, dermatitis, fleas and intestinal parasites can cause similar symptoms to food allergies.

Your vet will have the experience to make a definitive diagnosis.
Diagnosing a food intolerance or allergy is usually done through a process of elimination.
But once other causes of your cat’s problems have been ruled out and a food allergy is known to be the culprit, that’s just the beginning.
Why? Once you know what the problem isn’t, finding out what it is can take longer.
What Is a Food Trial?
Food trials are the usual way of finding out what is triggering your cat’s food allergy. This is done through an elimination diet.
For around 12 weeks, your cat will be fed a food that he has never eaten before.
This limited ingredient cat food will contain one carbohydrate and one protein.
Your vet may suggest a prescription diet or a commercially available food that meets these requirements.
Some cats develop allergies to many common foods.
In these cases, your vet may suggest using prescription food containing hydrolyzed proteins.
That means that the protein used to make the food has been deconstructed into tiny molecules.
This makes it virtually impossible for the cat’s body to recognize the protein source and have an allergic reaction to it.
Alternatively, your vet may suggest using a raw diet that you can make yourself at home.
Other Tips to Remember for a Cat Food Trial
When your cat is undergoing a food trial, don’t feed your cat anything other than an agreed-upon protein and carbohydrate.
At the end of the 12-week elimination diet, you can start to add one new ingredient to his food at a time.
That is, as long as your cat has not suffered an allergic reaction.
Your vet will tell you what to add to your cat’s diet, but these will be ingredients that were previously in the cat’s food.
If all goes well and your cat shows no signs of an allergic reaction, add a further ingredient to his ration and so on.
Continue to add new ingredients to the food until your cat has an allergic reaction.
That will enable your vet to identify the item that is causing the problem.
However, some cats are allergic to more than one thing. Continue the food trial until you’ve eliminated everything that was in your cat’s old diet.
Once the problem ingredient is found, your vet helps you select a diet for your cat that he can eat safely without more allergy troubles.
Food Trial Dos and Don’ts
During your cat’s food trial period, there are a few things to remember if the elimination diet works:
- Stick to the prescribed diet and don’t feed your cat anything that isn’t included in it.
- Do not feed your cat treats; these could contain allergens.
- Do not add supplements or flavored medication to your cat’s food.
- Do not allow your cat to play with flavored plastic toys. Some of these contain potential triggers of food allergies.
What Is Limited Edition Cat Food?
Limited ingredient cat food for allergies is very similar to hypoallergenic cat food.
Both these types of cat food are given to cats that have food intolerances or allergies.
Limited ingredient cat food usually contains a single carbohydrate source and a single protein source, preferably something your cat doesn’t typically eat.
By feeding your cat a limited ingredient diet, you’re aiming to remove whatever substance is triggering the allergy or food intolerance.
