Best Food For Cats With Allergies

If you have a cat who’s sensitive to certain ingredients you may be asking “what is the best food for cats with allergies?” Whether your cat has itchy skin or a chronic infection, it’s not uncommon for food to be the culprit.

In this post you’ll discover what causes allergies, signs to look for and some of the best food you can give your cat. In addition, how to ensure your cat is getting all the vital nutrients she needs.

I don’t have any medical training, and advice I share here is from research or my own experience. If your cat develops any unusual symptoms it’s important to see your vet first before assuming it’s an allergy.

What causes food allergies in cats?

Just as people develop food allergies, so can our pets. Similarly, adverse reactions to certain foods can either be an allergic reaction which is more serious, or an intolerance which is less serious.

It doesn’t matter how old your cat is, the sex or breed, an allergy can develop at any time. Causes are often low quality proteins found in some cat foods.

For example, these can be found in foods containing beef, fish, and some dairy ingredients. As cats don’t normally eat flavorings, dyes, or preservatives, these could trigger an allergic reaction.

However, it takes a few exposures to such allergens before symptoms start to show. Typically, your cat would need to eat foods containing these ingredients at least several times before any reactions start to develop.

How food allergies in cats are diagnosed

If you suspect your cat has a food allergy it’s a good idea to consult your vet, especially if changing food hasn’t worked. After giving your cat a physical examination to rule out any infections your vet will begin the process of elimination.

This involves introducing new foods into your cat’s diet that she hasn’t had before. During this time you mustn’t give any of the original food your cat was eating.

You’re normally advised to continue this for at least eight weeks. This is to allow plenty of time for any symptoms to start appearing.

The type of food recommended will be very bland, and you will be asked not to offer any treats no matter how much your cat pesters you! In addition, if your kitty enjoys a wander outside you must be very mindful of neighbors giving her the odd titbit.

As cat parents, we know just how cunning felines are! My previous cat used to knock on a neighbors front door knowing she’d give her biscuits!!

Anyway, if your cat is fine on the new diet, your vet will start to gradually introduce proteins. This won’t be a quick process and will require patience.

If your cat responds badly to a certain food, chances are the culprit has been found! Once you know exactly what triggers your cat’s symptoms you must eliminate it from her diet.

Can boosting your cat’s immune system help alleviate food allergy symptoms?

Many health problems including food allergies can often be the result of an imbalance of good and bad gut bacteria. This doesn’t only apply to humans but our pets as well.

Maintaining healthy gut bacteria is essential for your cat’s health and wellbeing, just as it is for you. Boosting the immune system with foods containing prebiotics and probiotics may help lower the risk of developing food allergies.

Some cat foods contain a mix of probiotics and antioxidants to help boost immunity and support health. In addition you can also get supplements especially designed for cats and dogs.

However, you may want to ask your vet’s advice before giving your cat a supplement. This especially applies if she has any allergy symptoms such as itchy skin or diarrhea.

What are the signs of food allergies in cats?

One of the most common signs is vomiting. Though cats do throw up the occasional hairball, or regurgitate food, frequent vomiting may be the result of a food allergy. However, you MUST get your cat checked out by a vet to rule out anything more serious.

Itchy, inflamed skin can be another sign your cat has a food allergy. However, it could also indicate a flea infestation! Fleas and ticks are common and can easily be treated.

Poor coat, and hair loss may be yet another sign your cat has an allergy to her food. Although, this could also be caused by obsessive grooming, or even stress.

Lastly, wheezing or coughing, though rare, could possibly indicate an allergy. NEVER let any respiratory problems continue as they require urgent medical attention.

Some of the best food for cats with allergies

The following cat foods are what I consider the best for allergies based on my own opinions. I may receive a small commission for any sales made, but this in no way reflects the price you pay.

In addition there are no fillers to bulk out the food which could be another trigger for sensitivities. Plus, the addition of essential vitamins and minerals boosts antioxidant levels.

It’s been found that a build up of oxidants in the body can result in food allergies. While there’s no evidence to support a cure, animal studies have shown a reduction in allergic responses.

The products is advertised as being easy to chew and swallow as well as having a crunchy texture. As most cats enjoy crunching kibble, this is another plus point.

Your cat’s recovery from a food allergy

It can take a while for food allergy symptoms to disappear, even after your cat has started a new diet. Always avoid low quality, cheap cat food, and monitor for any changes or improvements.

Though I’ve shared what I believe to some of the best food for cats with allergies, it’s important to consult your vet if your cat shows any symptoms. Allergies can occur for a variety of reasons and may not always be caused by food.

In addition, some symptoms may not be allergy related and could possibly be a sign of something else. If you’ve enjoyed this post and found it useful please share. Also, feel free to share this pin on your “pets” board.

  1. Although my cats do not seem to have any food allergies, one of them had an allergic reaction to a plant. It was, unfortunately, not a plant on my property, but outside of my property, so I could not check what it was. Luckily, with treatment he got better and the allergy is gone now – and the plant may be gone now too, since it’s dry season. However, I do have to find out what plant it is, or in next rain season I will have to find some preventive measures; I will check with the vet.

    The only brand I know is Taste of the Wild and I have heard much good about it. I love that it also includes fruits and vegetables and no grains. Although cats are carnivores, they do need their vitamins too. I think I may try out Taste of the Wild. The others also look like high quality foods. Even without an allergy, I think that feeding my cats one of these brands will do them a lot of good.

    • Hi Christine, sorry to hear your cat had an allergic reaction to a plant, but glad he’s ok now. Some plants can be quite toxic to cats, just as they can be to humans. Yes, Taste of the wild seems to be a popular brand of cat food with plenty of added nutrients. Glad you enjoyed this post and thanks for stopping by:)

  2. Hey,

    I am going to share this article with my friends because they have a cat that has allergies and they have been struggling in finding foods for him that doesn’t kick off his allergies.

    I will encourage them to comment on the post and if they have any questions then they should get in touch with you. If that is OK with you?

    Thank you for sharing and keep up the great work.

    All the best,


    • Thank you Tom:) I hope your friend finds this post useful and decides to try some of the cat foods I shared here. It can be just as hard to overcome allergies in our pets as it can be for us. Yes, absolutely, tell your friends to ask questions if they want. As I mentioned in the post, I’m not medically trained, but I’ll try and help if I can:)

  3. Hey Kathy, thanks for sharing this post. At first, I thought it’s just going to be a list of foods for cats with allergies. I wasn’t expecting to find so much great information about what causes these allergies ad how to diagnose them. Very helpful!

    So basically, these manufacturers took care to exclude those ingredients that usually trigger allergic reactions as well as contribute to developing the allergy altogether, right?

    • Thank you Ivan, glad you enjoyed this post. I always try to be informative as well as share products. This is so that visitors have a bit of understanding about cat health and wellbeing. Though the foods aren’t specifically aimed at cats with allergies, the ingredients are more natural compared to other brands. Plus, the addition of nutrients helps strengthen the immune system. This in itself may help alleviate some of the symptoms associated with food allergies in cats. Thanks for stopping by:)

  4. This post is so helpful and educational. I really liked that you also have shared with us how to diagnose a possible allergy. I am not gonna remember it all for sure so I’ll bookmark your site. I’ll also forward this post to my friends, I remember that one cat they used to have back in days had some problems, I am not quite sure whether it was an allergy or something else but I assume this post might be very informative for them.
