When should cats not eat tuna?

According to the American Society for preventing Cruelty to Animals, feeding your cat tuna now and then as treats, in small amounts is fine, however, there are cases in which you should not feed your cat tuna.

Before taking any decision, make sure you consult your veterinarian. Here is a list of cases in which you should avoid feeding your cat tuna:

1) Your cat has tuna allergy:

Even though tuna can be one of your car’s favourite foods or treats, it can still develop an allergy towards it. That can be towards any kind of tuna, whether fresh or canned tuna. Some cat owners would believe that human-grade tuna is better for their cats, but they can still develop an allergy towards it as well.

Causes of tuna allergy for cats:

Food allergy can be caused by a hypersensitivity reaction to a particular ingredient or food, in this case, tuna.

The immune system of your cat reacts to tuna as something dangerous, even though it completely harmless, it sees it as a threat and urges the body to act in response to that, to shield and protect itself.

Symptoms of food allergy because of tuna:

  • Erythema.

  • Alopecia.

  • Indolent ulcers.

  • Diarrhea.

  • Weight loss.

  • Vomiting.

  • Pain in the abdominal area.

  • Pruritus, which is the desire and sensation that urges the cat to scratch, rub, lick, or chew its skin. This can be the head, neck, or ears areas.

  • Conjunctivitis.

  • Papules.

  • Dermatitis, which is also a skin condition.

  • Inflammatory skin problems, also know as Granulomas or eosinophilic granuloma complex.

  • Flatulence.

  • Inflammatory bowel disease.

  • Inflammation of the cat’s nose, also known as rhinitis.

  • Pancreas problems.

  • Liver conditions.

  • Kidney problems or kidney disease.

What I have to do?

In case your cat displays these symptoms if and when tuna is part of its diet, you should take it to the vet immediately. Your veterinarian will run a full physical exam on your cat to eliminate the other possible condition such as gastrointestinal parasites or hypersensitivity from flea bites.

The vet will also ask you about the symptoms, and when they started, so make sure you give the exact details.

Since there is no clear blood test to diagnose a food allergy, the method that is used the most is the elimination diet trial. Your vet will ask you to eliminates tuna from your cat’s diet for at least 12 weeks to see.

It can be treated?

Studies have shown that food allergies (in this case tuna allergy), cannot be treated 100 %, but your vet would prescribe medications as a secondary treatment to relieve your cat’s symptoms. Your cat, however, can recover from it entirely, the speed of recovery depends on the severity of the symptoms it has experienced.

2) Kidney disease:

If your cat suffers from kidney disease or kidney failure, there is a treatment and a specific diet that your vet will prescribe for you. Diets for cats with chronic kidney disease are usually low in sodium and phosphorus.

You must make sure that you sustain adequate nutrition for your cat, in order to slow down the progression of its chronic kidney disease. Consult with your veterinarian before choosing to eliminate tuna or add it to your cat’s diet, especially if it has a chronic disease.

3) Diabetes:

If your cat has diabetes, you must be very careful with the amount of tuna you give it. Tuna is very rich in protein and low in fat, and since cats are carnivores, they can quickly turn excess protein levels in their system into glucose.

This would lead the blood sugar levels to spike. If you only treat your cat with one level teaspoon of tuna once or twice a day, it should be fine.

For cats with diabetes, it is best to keep tuna treats to a minimum, to avoid any rise in their blood sugar levels.

Before you make any decision concerning the food you provide for your cat, make sure you consult with your veterinarian to help you choose a balanced and healthy diet for it.

4) Sensitive stomach:

Sometimes cats develop a sensitive stomach due to eating habits, or other underlying conditions. Being careful with their diets and what kinds of food to provide for them is very important.

Cats can suffer from indigestions, and it can vary from one cat to another concerning the severity and the duration. In some cats, it can be more long-lasting than in others.

Your cat can have a sensitive stomach when it comes to tuna if they overeat it, especially if you are not following a moderate way of feeding them.

So, make sure you do not give large amounts of tuna to your cat, a sensitive stomach can also be due to running or other physical activities right after eating.

A cat with a sensitive stomach would show symptoms as can casual vomiting and diarrhea. Some vets advise taking away your cat’s water and food for 12 hours after they vomit, don’t worry cats survive without eating and drinking for longer than that, however, if your cat displays any of those symptoms repetitively, make sure you schedule an appointment with your veterinarian. Do not take any actions without consulting first.

It has many health benefits, and it is a healthy and delicious treat. However, you must be careful when dealing with the amounts of tuna you provide for your cat.
