Homemade cat food

Mackerel & Oat Cookies

Crunchy little baked cookies built around omega-rich mackerel and gentle oats. They bake up firm, store well, and the smell alone will bring your cat running.

About 20 small cookies

🧺 Ingredients

  • 1 can mackerel in spring water (drained) — about 110g
  • 1 egg
  • 4 tbsp oat flour (or porridge oats blitzed fine)
  • 1 tbsp plain unsweetened pumpkin purée (optional, for binding)

👩‍🍳 Method

  1. Preheat the oven to 180°C (350°F) and line a baking tray with parchment.
  2. Drain the mackerel well and mash it thoroughly in a bowl, removing any large bones.
  3. Add the egg, oat flour, and pumpkin purée, and mix into a stiff, mouldable dough. Add a little more oat flour if it feels wet.
  4. Pinch off small pea-to-marble-sized pieces, roll into balls, and flatten into little cookies on the tray.
  5. Bake for 12–15 minutes until firm and golden at the edges.
  6. Cool completely on a wire rack before offering one to your cat — they should be crisp, not warm.
Nutrition: Mackerel is exceptionally rich in omega-3 fatty acids (EPA and DHA), which support skin, coat, and joint health. Oats add gentle, low-allergen fibre, and egg contributes complete protein and biotin.

📝 Notes

Store in an airtight container in the fridge for up to 5 days, or freeze for up to 2 months. Always choose fish in spring water, never in brine or oil. Treats like these should make up no more than about 10% of your cat's daily calories — the rest must come from a complete, balanced cat food.

⚕️ Before you cook for your cat

  • Homemade food must be balanced. Cats need taurine, and deficiency causes heart and eye disease.
  • Treat recipes are supplements to a complete diet, not a replacement for it.
  • Check any new ingredient against the toxic-foods list, and ask your vet before switching diets.
