Can Cats Eat Barley?

Yes — plain, cooked barley is generally safe for cats in small amounts, but it is not a necessary part of a cat's diet. Because cats are obligate carnivores, barley should only be an occasional treat and not a meal replacement.

Plain cooked barley is generally safe for cats

Barley is not known to be toxic to cats, and cereal grains can appear in some commercial cat foods. The main concerns are digestive upset, added seasonings, and feeding too much of a plant food to an obligate carnivore.

How urgent is this?

Emergency

Go to the ER now

  • ● Trouble breathing, repeated coughing, or choking after eating dry barley, barley flour, or a large clump of food

Monitor

Watch at home, call if it worsens

  • ● Your cat ate a small amount of plain, cooked barley and is acting normally
  • ● Mild gas or one soft stool after a small taste
  • ● Your cat nibbled barley grass or a small amount of barley from commercial cat food

How to Safely Feed Barley to Your Cat

If you choose to offer barley, keep it plain and minimal. Cats do not need grains for balanced nutrition, so barley should only be an occasional extra, not a regular part of the diet.

  • Only offer barley if it is fully cooked and soft — raw or undercooked barley is harder to digest
  • Serve it plain with no salt, butter, oil, broth, garlic, onion, or spices
  • Offer only a very small amount, such as a teaspoon or less mixed into food for most cats
  • Keep all treats and people foods, including barley, to no more than about 10% of your cat's daily calories
  • Stop feeding it if your cat develops vomiting, diarrhea, gas, itching, or refuses food, and call your vet if you are unsure

Common Questions

Is barley toxic to cats?
Barley itself is not known to be toxic to cats. The bigger risks are stomach upset, choking on dry grains, or barley being part of a recipe that includes toxic ingredients like onion or garlic.
Can cats digest barley?
Cats can digest small amounts of cooked barley, and grains may be included in some commercial cat foods. However, cats are obligate carnivores, so barley should only be an occasional treat rather than a meaningful source of nutrition.
Is barley safe for kittens?
A tiny taste of plain cooked barley is unlikely to be harmful, but kittens should get their nutrition from a complete and balanced kitten food. Because kittens are small and more prone to digestive upset, it is best to avoid extra foods unless your veterinarian says otherwise.
What is the difference between barley safety in cats and dogs?
Barley is generally considered safe for both cats and dogs when it is plain and cooked. The difference is nutritional: dogs can use plant ingredients more easily, while cats are obligate carnivores and should not eat much barley. In cats, even safe plant foods should stay a very small part of the diet.
Can cats eat barley soup, barley bread, or seasoned barley dishes?
These are not good choices for cats. Prepared barley foods often contain salt, butter, oils, onions, garlic, or other ingredients that can be unsafe for cats. Plain cooked barley is the safest form if you offer any at all.
