Buster has been eating the same brand of cat food for a long time, but his face, head, abdomen, limbs, paws, and groin sometimes get very itchy and swollen. He moves his bottom around on the carpet every once in a while, and when he eats certain kinds of food, he sometimes starts throwing up or having soft stools.
After some detective work, the seafood flavors seem to be the culprit for his troubles. He doesn’t seem to have any other food allergies because it doesn’t bother his skin or stomach.
“Aren’t cats supposed to love fish? Buster always likes a little treat that tastes like seafood,” you may be asking. It’s interesting that cats can be allergic to some things, even if they really like the taste of them.
As cat owners we want to spoil our furry friends with tasty treats and a variety of proteins in their diet. Shrimp is a delicacy that many cat parents think would make an exciting snack or addition to their cat’s normal food. However, did you know that cats can actually be allergic to shrimp? I was shocked when I first learned about this relatively common food allergy in cats.
In this article, we’ll dive into the details of shrimp allergies in cats. We’ll cover the symptoms to look out for, how to get a diagnosis from your vet, treatment options, and tips for preventing reactions. My goal is to spread awareness about this issue so that other cat lovers can avoid making the same mistakes I did.
How Common Are Shrimp Allergies in Cats?
While not as widespread as allergies to foods like beef or dairy, shrimp allergies are not unheard of in cats. Approximately 1-2% of cats are estimated to have an allergy to shellfish like shrimp, crab, or lobster.
I first discovered my cat Charlie’s sensitivity when I shared a few tiny cooked shrimp with him as a special treat. He gobbled them up happily, but a few hours later I noticed him scratching his neck repeatedly. Over the next day, he became lethargic and developed patches of hair loss. It wasn’t until I brought him to the vet that we determined he likely had an allergic reaction to the shrimp.
Symptoms of a Shrimp Allergy in Cats
Cats with a shrimp allergy can develop a range of troubling symptoms, usually within hours of ingesting it. Here are some of the most common signs:
- Itchy skin, repeated scratching or licking
- Hair loss or skin lesions
- Swelling around the face and neck
- Vomiting or diarrhea
- Sneezing and watery eyes
- Lethargy or depression
In rare cases, cats may also experience anaphylaxis – a life-threatening reaction that causes severe swelling and difficulty breathing. This requires immediate emergency veterinary care.
If your cat displays any abnormal symptoms after eating shrimp, consult your vet right away. They can help determine if an allergy is to blame and provide proper treatment.
Diagnosing a Shrimp Allergy in Cats
There are a few methods vets may use to diagnose a shellfish or shrimp allergy in felines:
-
Elimination diet trial – Your vet will prescribe a restricted diet containing novel proteins your cat has not eaten before, like kangaroo, bison, or venison. If symptoms resolve, they will then reintroduce shrimp to see if it triggers a reaction.
-
Blood testing – A blood sample can be analyzed for IgE antibodiesproduced in response to specific allergens like shrimp proteins.
-
Skin testing – Injecting small amounts of allergen extracts into the skin and evaluating the reaction.
Once a shrimp allergy is confirmed, avoiding any further exposure to it is key to managing the condition.
Treating a Shrimp Allergy in Cats
Treatment focuses on alleviating symptoms and strictly avoiding the trigger allergen. Here are some tips for managing a diagnosed shrimp allergy in your cat:
-
Transition to a hypoallergenic diet – Your vet may prescribe a hydrolyzed protein cat food made with specially processed proteins to remove potential allergens.
-
Avoid all shellfish – Do not feed your cat any shrimp, lobster, crab, crawfish, or related species as they often cause cross-reactivity.
-
Check all ingredients – Carefully read labels on all food, treats and medications to ensure they do not contain shellfish. Terms like “fish,” “seafood,” or “meat” are too vague.
-
Wash hands/bowls thoroughly – Prevent cross-contamination by washing hands and your cat’s food bowls after handling any shrimp products. Even tiny residues can trigger a reaction.
-
Medications – Your vet may prescribe antihistamines, steroids, or other drugs to reduce allergic symptoms. Use only as directed.
-
Emergency treatment – If a severe reaction occurs, follow your vet’s instructions for emergency care which may include injectable epinephrine, steroids, or hospitalization.
With diligence and care, most cats with a shrimp allergy can enjoy a comfortable, high-quality life. Be sure to work closely with your veterinarian to find the safest and most effective treatment plan for your individual pet.
Are Other Seafood Allergies Common in Cats?
While shrimp allergies seem to be one of the most prevalent, cats can also develop sensitivities to other types of seafood:
-
Fish – Allergies to fish like tuna, salmon, or cod are probably the most common seafood sensitivity in cats. Symptoms are similar to shrimp allergies.
-
Shellfish – In addition to shrimp, cats may react to lobster, crab, crawfish, oysters, clams, scallops, mussels, and related shellfish.
-
Fish meal or by-products – Even fish parts used in some cat food recipes can trigger reactions. Always check ingredients.
As with any suspected food allergy, be sure to consult your vet if your cat displays any abnormal signs after eating seafood. Never attempt to self-diagnose or restrict your cat’s diet without professional guidance.
Preventing Shrimp Allergies in Cats
Here are some tips to help avoid triggering a shrimp or seafood allergy in your feline friend:
-
Avoid feeding cats any shrimp, shellfish, fish, or seafood without consulting your vet first. It’s simply not worth the risk.
-
Check all cat food labels and do not purchase any containing fish, shellfish or seafood ingredients. Terms like “meat” or “fish” are too vague.
-
Prevent access to food prep areas where shrimp is being handled and thoroughly clean surfaces afterward.
-
Supervise your cat anytime shrimp or seafood is being cooked or eaten in the home. Even small amounts can trigger a major reaction in sensitive cats.
-
Inform any pet sitters or caretakers about your cat’s seafood allergy so they do not accidentally expose your cat while you are away. Post a warning sign as well.
-
Have emergency contact information handy, as well as instructions from your vet on treating a reaction should one occur. Act quickly at the first signs of an allergy flare-up.
While it’s impossible to control everything our cats are exposed to, avoiding known allergens is the most reliable way to prevent adverse reactions. Do your part to keep your cat safe and healthy!
My Lessons Learned as a Cat Owner
After my cat Charlie had his first reaction, I felt so guilty that my innocent attempt to spoil him resulted in so much suffering. Here are a few key lessons I learned from this experience:
-
Never assume a human food is safe for felines without consulting your vet first. Cats have very different nutritional needs.
-
Report any unusual symptoms after feeding something new to your vet promptly. Allergies can worsen with repeated exposure.
-
Always read packaging labels carefully to check for allergens inside commercial cat foods or treats. Marketing images can be misleading.
-
Don’t beat yourself up over mistakes! Even experienced cat owners can unknowingly trigger allergies. Learn from it and move forward.
-
Keep emergency numbers and treatment info handy just in case. Having a plan gives peace of mind.
While challenging, managing Charlie’s shrimp allergy has made me a more attentive and informed cat guardian. I hope by sharing my story, it will empower other cat lovers as well. We all want our furry family members to live long, healthy, and happy lives!

Identifying Cat Food Allergies
Although it is not very common, cats can be allergic to fish and seafood. This usually comes to light after several veterinary visits for persistent scratching, skin infections, diarrhea, and vomiting. Some of the other reasons to become a regular at your local vet’s office are visits for blood work and sometimes just for support. It can be a frustrating path.
After an elimination diet trial and/or skin testing, a veterinary dermatologist will usually tell you what the allergen is. Then you can start looking for a food and treats that Buster can eat without any discomfort.
