Can cats eat mussels, and why?
A little plain cooked, de-shelled mussel is a safe occasional treat for cats. Raw shellfish carries bacteria; cook well and skip the shell and seasoning.
Cats are obligate carnivores: they must get most of their nutrition from meat and need nutrients such as taurine that only animal products provide. They lack some enzymes for processing plants and carbohydrates, so fruit and veg offer little benefit and can upset their stomach; many cats are also lactose intolerant.
How to feed mussels to cats
- •How much: A small amount of cooked mussel meat occasionally.
- •How often: An occasional treat, not a daily food. Any treat should be occasional and tiny — no more than about 10% of daily calories — and never replace a balanced cat food.
- •Young pets: Kittens have sensitive digestion and high growth needs, so introduce new foods cautiously and ask your vet.
- •Preparation: Always wash fresh produce, remove any pips, stones, seeds, peel or tough skin where relevant, and serve it plain — never with salt, sugar, oil, butter or seasoning.
