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

Pox’s Story Does it make sense to treat hyperthyroid in a fourteen-year-old, mostly outdoor cat? That’s what we were asking ourselves in the summer of 2013. Pox let me know his opinion by following me around all summer, talking continually. He plainly said, “I feel lousy;... read more »
