Have you ever heard about grain-free cat food? Here’s everything you need to know about it.

What is grain free cat food?

Normal cat food often contains grain in the form of corn, rice or wheat. Grain free cat food is, basically, what it says on the tin - it contains no grains whatsoever!

Why go grain-free?

Some cats do develop a nasty grain allergy. If your cat is allergic to grains, it makes sense to switch to a grain free cat food.

If your kitty is doing fine with grain in their diet, there’s no urgent rush to change. But if you can afford the extra cost, there’s no harm in trying a grain free food, which may be better for their long-term health.

Opting for grain free cat food is a good way to closely mimic your cat’s natural diet, as good-quality grain free foods usually contain a higher percentage of protein.

Symptoms of grain allergy in cats

Noticed some unusual symptoms in your kitty, which seem to be intensified after eating a meal? It could be a grain allergy. Look out for the following symptoms, which could indicate a cat grain allergy:

  • Itchiness
  • Hair loss and bald patches
  • Inflamed, sore skin and scabs
  • Vomiting and diarrhoea
  • Excessive grooming
  • Lip ulcers
  • Ear infections
  • Cracked paw pads
  • Coughing

Do bear in mind that a grain allergy could turn up out of the blue, even if your cat has been eating cat food with grains for years.

If you suspect these symptoms could be down to a grain allergy, you’ll need to switch to a grain free cat food and see if the symptoms ease. If symptoms are severe, we’d also recommend taking your cat to the vet in case an underlying condition is present.
