Key Features to Look For
Finding the right food is important. Look for these key features:
Low Iodine Levels
Cats with hyperthyroidism have too much iodine. Iodine helps make thyroid hormones. Food for these cats must have low iodine. This helps control the thyroid hormones.
Complete and Balanced Nutrition

Palatability (Tasty!)
Your cat has to eat the food! Find a food your cat likes. If your cat doesn’t eat, it won’t help. Try different flavors and textures to see what your cat enjoys.
Important Materials
What’s inside the food matters. Here are some important things to consider:
