4 Best Canned Food for Hyperthyroid Cats – Updated 2022
Your cat could be hyperthyroid if they are overactive or have an enlarged thyroid.
Hyperthyroid cats need to consume foods high in potassium (potassium helps prevent muscle tremors) and high protein (protein is essential to good health).
If you’re wondering which food is best for hyperthyroid cats, here’s a list of canned foods that should make the top of your cat’s diet.
What To Look For In The Best Cat Food?
Hyperthyroid Cats Need Highly-Digestible Protein.
When it comes to muscular mass, hyperthyroid cats have two challenges. In addition to their high metabolic rate, the majority of them are in their golden years.
According to recent findings, the nutritional requirements of the elderly are quite comparable to those of kittens, who have high protein and calorie requirements. They begin to lose muscular mass if these demands are not supplied.
Choose protein-rich meals with at least 50% of the calories coming from animal sources. Species-appropriate and easily digested proteins are the finest sources of protein.
Pea protein, potato protein, wheat gluten and corn gluten meal are all high-protein fillers that your cat has to avoid.
Choose A Diet That’s Less Than 10% Carbohydrate On A Dry Matter Basis.
Insulin resistance and decreased glucose tolerance are common side effects of hyperthyroidism in cats. In this stage, you are at risk for developing type 2 diabetes.
However, hyperthyroid cats are still sensitive to sugar and need a carbohydrate diet that is carefully monitored to prevent full-blown diabetes.
What To Avoid When Feeding A Hyperthyroid Cat?
Avoid Fish-Based Foods.
According to a research conducted in the year 2000, cats who prefer fish or liver and giblets taste canned cat food have a higher chance of developing hyperthyroidism.
The iodine content of seafood and other water species is higher than that of land-based diets. Thyroid function relies heavily on iodine, so this might explain some of the symptoms, but it’s not apparent that iodine deficiency is the primary issue.
Most Fish Is Contaminated With Toxins, Including PBDEs
In the late 1970s, these flame-retardant compounds were widely utilized to coat everything from pajamas to drapes.
PBDEs were mostly phased out in the early 2000s in the United States and Europe due to their reputation as recognized endocrine disruptors. However, it does not imply that they are no longer present in the world.
These poisons persist in the soil, dust, streams, and in the bodies of humans and animals, as well as in the ocean, and can be found in canned fish.
In hyperthyroid cats, PBDEs are more concentrated in the circulation.
If Feeding Canned Food, Ensure That The Can Is BPA-Free.
Food canned in pop-top containers is linked to an increased risk of thyroid disease in cats. As a result, BPA-coated cans of cat food are becoming more common. Thyroid function is altered as a result of BPA acting as a thyroid receptor antagonist
Don’t Feed Your Cat Soy
Scientists found that cats on a soy diet for three months had “significantly greater total thyroxine (T4) and free T4 (fT4) concentrations,” but “unchanged total triiodothyronine (T3) concentrations,” when they fed 18 healthy adult cats a soy or a soy-free diet.
The amount of thyroid hormone secreted by the body was slightly but significantly influenced by a soy-based diet.
Should You Feed Your Cat A Prescription Diet For Hyperthyroidism?
The most popular prescription cat food for hyperthyroidism is Hill’s Prescription Diet y/d. On a dry matter basis, this item contains less than 0.32 ppm iodine.
According to the paper linked above, “all hyperthyroid cats managed with Hill’s Prescription Diet® y/d®
Feline as the sole source of nutrition have become and remained euthyroid (having normal thyroid function) as long as the cat had no access to other sources of iodine” as of 2011, when the article was written.
Thyroid hormone production is slowed by a lack of iodine in a low-iodine diet. It does not address an overly big gland.
Adenomas can turn into carcinomas even if they are treated with this medication. There isn’t much of a difference.
How Much Iodine Does A Normal Cat Require?
Due to the wide range of iodine concentrations found in various foods, it is difficult to determine how much iodine cats should consume.
1.3 ppm of dietary iodine was recommended by the National Research Council in 2006. Hill’s Pet Nutrition has undertaken new study that reveals that the need is closer to 0.46 ppm than previously thought.
The Hill’s diet has just 0.32 ppm iodine. If we believe that iodine is solely required for the manufacture of thyroid hormones, we still don’t know how restricting our intake of the mineral will impact our health over time.
We sent samples to an ISO 17025 recognized laboratory for food testing and analysis in addition to doing our own qualitative study of the brands examined here.
As All About Cats supported the whole testing procedure, the corporations involved had no involvement or influence in any way.
The precise macronutrient and micronutrient composition of any dish may be determined by analytical testing at a food chemistry laboratory.
As a result of the testing, you can be assured that you’re only giving your cat the finest food possible.
Top Best Cat Foods For Hyperthyroidism
Top Pick: Hill’s Prescription Diet Thyroid Care y/d Feline Canned Review
Water, pork liver, pork by-products, chicken, and corn flour are the first five ingredients.
If you have hyperthyroidism, don’t rely on this meal as a substitute for lifetime medication or a thyroidotomy.
The thyroid is deprived of fuel, yet the evolution of a thyroid tumor is unaffected. The tumor will continue to develop, and it may turn into a carcinoma at some point in the future.
Cats on this diet must consume it for the remainder of their lives, or they will relapse and have to start over. Even typical therapeutic foods, such as those for CKD, diabetes or pancreatitis are out of the question.
Finally, the diet consists of a high-carbohydrate, low-protein one. About 27 percent of the canned food is protein, 24 percent of it is carbohydrates, and the rest is fat.
If you’re a senior cat who’s already prone to muscle loss, this isn’t the best way to distribute calories. To maintain healthy muscular mass, senior cats need high-quality protein, and this diet doesn’t provide it.

Thyroid hormone levels were found to be increased in 21% of cats over the age of 10 who provided blood samples for testing.
Finding a diet that addresses both thyroid function as well as senior health is important because so many seniors suffer from some degree of hyperthyroidism.
Hyperthyroidism cannot be cured by this cuisine, but it may be maintained without worsening the condition in your elderly loved one.

Omega-3 fatty acids, which reduce inflammation and benefit the skin and coat, are also present in high concentrations in this diet, which further aids in muscle growth. Keep in mind that the dish contains iodine-rich green-lipped mussels.
To reduce iodine consumption to a minimum, you may wish to alternate this food with a seafood-free formula.

Conclusion
This is where I can give a list of canned foods for hyperthyroid cats that I would recommend. The top three are: Blue Buffalo Wilderness Preserves, Pedigree Canned Kitten Food, and Hill’s Science Diet Canned Formula Feline.
If you can afford it, you can also give your cat food that is a little bit higher in protein and fat. I also recommend that you read through the nutrition label before feeding your cat this type of food.
