What Should I Feed My Hyperthyroid Cat?

 

“What’s the best diet to feed my hyperthyroid cat?”

The best diet for your hyperthyroid cat satisfies his/her nutritional requirements as an aging carnivore recovering from a muscle-wasting disease, and avoids chemicals that may contribute to thyroid disease. We encourage you to read cat food labels and consider these guidelines.

It is best to feed:

Canned or raw diets, that contain little to no fruits, vegetables, or grains. Any canned cat food is better than any dry, which contains too much carbohydrate and plant-based protein. Meat by-products are fine for carnivores: they’re simply protein sources such as organ meats and entrails that people don’t find appetizing. Gravy foods tend to be high in carbs, so pates are a better choice.

Motivated cat owners may check out the website (www.catinfo.org), which gives nutrient breakdown of various prescription and over-the-counter diets in the link “Protein/Fat/Carbs Chart”. It turns out that many of the otc canned diets have an acceptable composition of these, and are reasonably low in phosphate, i.e.:

  • >40% meat protein (>12g/100 kcal)
  • <10 % carbohydrates
  • 50 % fat
  • <250 mg/100kcal phosphate

Note: these percentages are based on dry matter, metabolizable energy, unlike those on the can label

It may be best to avoid:

  • SOY-containing foods
  • BPA in canned food linings
  • Fish
  • Plastic food and water bowls (replace with glass, ceramic or metal)
  • Storing food in plastic containers
  • Ultra-high or ultra low iodine diets
