Why go grain free?

How do I know if my cat needs grain free food?

Some cats are more sensitive to ingredients like wheat, corn or soy, and that’s where grain free cat food can help. Signs your cat might benefit from a grain free diet include frequent scratching, itchy skin, loose stools, vomiting or a dull coat. You might also notice recurring ear infections or excessive licking. These symptoms can sometimes point to food sensitivities, and grains may be a trigger.

That said, not all cats need to avoid grains. It’s best to speak with your vet if you suspect a dietary issue. They can help you rule out other causes and guide you toward the best food for your cat’s specific needs.

Can I mix grain free dry and wet cat food?

Yes, and in many cases, it’s actually a great idea. Mixing grain free dry and wet cat food gives your cat the benefits of both formats. Dry food helps support dental health, while wet food boosts hydration, especially if your cat doesn’t drink much water. Together, they can offer a more balanced and satisfying diet.

Just be mindful of the total daily portion. Check feeding guides on both products and adjust based on your cat’s size, age and activity level. You don’t want to overfeed, even with high-quality food.

Do grain free diets help with hairballs?

They can, depending on the formula. Some grain free cat foods are designed with added fibre, omega oils or natural ingredients that support healthy digestion, all of which may help reduce hairball formation. A well-functioning digestive system is key to moving hair through the gut rather than having your cat cough it up.

If hairballs are a regular problem, look for grain free options labelled for digestive or hairball support, and consider brushing your cat more often to reduce excess shedding.
