Sainsbury’s Grain-Free Adult Cat Food is designed for cats that require a gentle, high-quality diet free from common irritants like wheat, maize, or other grains. Whether your cat has a known food sensitivity or you’re simply aiming to reduce filler ingredients in their diet, this grain-free range offers complete, balanced nutrition using easily digestible, natural ingredients.

Here’s why Sainsbury’s Grain-Free Adult Cat Food is a smart and health-conscious choice for adult cats in the UK.
Why Grain-Free Cat Food Makes a Difference
Cats are obligate carnivores, meaning they rely on meat-based proteins to thrive. Grain-heavy diets can sometimes lead to digestive upset, skin issues, or general discomfort in certain cats.
Supports Digestive Health and Comfort
Grain-free recipes are gentler on the stomach:
- Excludes common allergens like wheat and corn.
- Uses more digestible carbohydrate sources such as potatoes or peas.
Reduces Skin Irritation and Food Sensitivities
Food intolerances can manifest through itchy skin and digestive issues:
- Grain-free diets help reduce inflammatory reactions.
- Promotes healthier skin and shinier fur in sensitive cats.
