🧺 Ingredients

  • 80g plain cooked mackerel, skinned and boned (tinned in spring water, drained, works well)
  • 1 teaspoon finely chopped cooked spinach, cooled
  • 2 tablespoons plain water or unsalted fish stock, to loosen

👩‍🍳 Method

  1. Steam, poach or use plain tinned mackerel — never smoked, salted or in brine — and let it cool.
  2. Flake the fish carefully with your fingers, checking for and removing every bone.
  3. Cook a little spinach plainly with no oil, salt or seasoning, cool it, and chop very finely.
  4. Mash the mackerel with the tiny amount of spinach and enough water or stock to make a soft, spoonable mash.
  5. Serve a heaped teaspoon as a topper over your cat's usual food; refrigerate the rest in a sealed tub for up to three days.
Nutrition: Mackerel is packed with omega-3 fatty acids for a glossy coat and supple joints, while a trace of spinach adds a little vitamin K and iron without upsetting an obligate carnivore's balance.

📝 Notes

Oily fish like mackerel is rich and best kept as an occasional topper rather than a daily meal, and spinach should only ever be a pinch — it is high in oxalates, so cats with a history of urinary crystals or kidney disease should skip it and take the mackerel alone.

⚕️ 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.
