In some cases, cats diagnosed with hyperthyroidism can live longer, happier lives with the dietary management of their disease. One of the treatment options for hyperthyroidism in cats is dietary management with a low-iodine diet which in turn helps to lower their overall thyroid hormone levels. Whether you choose a commercially made prescription diet or a homemade diet, always consult with your veterinarian to ensure that your cat’s nutritional and clinical needs are being met. This is especially important because it is not uncommon that cats with hypothyroidism also suffer from kidney issues. In those cases, the diet will require a controlled level of proteins that vary depending on the stage of the kidney disease. 

Likewise, if a cat with hyperthyroidism is also receiving medical treatment or has undergone surgery or radiation therapy to treat the condition, the levels of iodine in the diet will need to be adjusted. 

Dietary management of hypothyroidism requires iodine levels to be limited to no more than 0.32 parts per million to adequately reduce the levels of thyroid hormones. But some hyperthyroid cats that are being treated with methimazole or have undergone radioactive iodine therapy or thyroidectomy can greatly benefit from high-protein and high-energy diets.

Your veterinarian is the best person to help you figure out the best diet for your hyperthyroid cat.

Ingredients for Homemade Hyperthyroid Cat Food

The best homemade hyperthyroid cat food for cats without kidney issues will contain little-to-no fruits, vegetables, or grains. Cats are obligate carnivores, so they require meat to sustain themselves. They can also be fed meat by-products, like organ meats or entrails, that aren’t particularly appetizing to people.

A cat with hyperthyroidism and kidney issues will require less protein, which is usually achieved by adding some grains into the diet.

Things to avoid:

  • Foods containing soy
  • Canned foods with BPA
  • Fish
  • Plastic food or water bowls (use glass, ceramic, or metal instead)
  • Storing food in plastic containers
  • Egg yolks
  • Dairy
  • Seaweed
  • Iodized salt
  • Carrageenan
  • Agar-agar

Low-iodine foods:

  • Beef
  • Veal
  • Lamb
  • Pork
  • Fresh chicken
  • Turkey

Essential Components

If you’ve decided to make homemade cat food, there are certain components that are essential for maintaining your cat’s overall health and well-being. These include:

  • Protein
  • Amino acids like arginine and taurine
  • Fatty acids
  • Vitamins
  • Minerals
  • Water

While cats can eat carbohydrates like corn and rice, they aren’t necessary. The only cats that benefit are those who need a bland diet for a few days, such as cats recovering from diarrhea, or in a long-term situation, cats that need to reduce the amount of protein in their diet such as in the case of cats with kidney disease.

Our 5 Homemade Hyperthyroid Cat Food Recipes

Note: These recipes have been approved by a veterinarian because they include only cat-friendly ingredients that are low in iodine content. These recipes are not meant to be fed as a staple diet. Depending on the exact cause of your cat’s hyperthyroidism, dietary management might not be a treatment option. Moreover, some cats suffering from hyperthyroidism might also suffer from concomitant kidney disease, which is important to consider when choosing the best diet. Since hyperthyroid cats have different needs, we urge you to please consult your veterinarian to help you decide on the best diet for your particular cat.

Dietary management is a very important part of the treatment of hyperthyroid cats. Salt and sodium are restricted and many cats see significant changes with dietary management alone. However, every case is different, and regular blood samples need to be done to monitor the cat’s thyroid hormones. Make sure to consult with your veterinarian before making any changes to your cat’s food. Most hyperthyroid cat foods are designed to maintain your cat’s overall health, keep a healthy weight, and reverse imbalances in their body.

Your vet can advise you regarding any treatments, medications, supplements, or any other dietary changes that are further needed to regulate your cat’s condition. If you don’t have time to cook for your cat, you can try a high-quality fresh cat food brand.
