Can cats eat sunflower seeds, and why?
Cats can have a tiny taste of plain, shelled sunflower seed but gain no benefit.
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 sunflower seeds to cats
- •How much: One or two shelled, unsalted seeds 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.
