Homemade cat food
Whitefish & Seaweed Iodine Flakes
A light, flaky topper built on gently poached white fish with the tiniest pinch of nori for natural iodine — a mineral the thyroid depends on. Perfect crumbled over a fussy cat's dinner.

🧺 Ingredients
- 1 white fish fillet (cod, haddock or pollock), about 120g
- 1 tsp finely crumbled plain nori (unsalted, unseasoned)
- 1 egg white
👩🍳 Method
- Poach the fish fillet in plain water for 6–8 minutes until it flakes easily, then lift out and let it cool.
- Carefully flake the fish, checking with your fingers for any bones and removing every one.
- Whisk the egg white and fold it through the flaked fish with the crumbled nori.
- Spread thinly on a lined tray and bake at 160°C (320°F) for 8–10 minutes until dry and crisp.
- Cool fully, then break into small flakes to scatter over meals.
Nutrition: White fish is lean, highly digestible protein, while a trace of nori supplies natural iodine — the building block the thyroid gland uses to make the hormones that govern a cat's metabolism.
📝 Notes
Use only plain, unseasoned nori — the flavoured sushi kind is loaded with salt and soy. A tiny pinch is plenty; seaweed is very concentrated in iodine and more is not better. Skip this recipe entirely for any cat diagnosed with hyperthyroidism or on a prescription thyroid diet, and check with your vet first if your cat has any thyroid history. Store flakes in an airtight jar for up to a week.
