Can Cats Eat Popcorn?

Only now and thenTreat size for a 10 lb adult cat: 2 or 3 pieces of plain air-popped popcorn, no kernels or hulls (a few calories)

Popcorn is an occasional treat at most, and only when it is plain and air-popped, with no butter, salt or unpopped kernels. The ASPCA lists air-popped popcorn among foods pets can share, and Tufts Petfoodology includes unsalted air-popped popcorn in its table of treat options for pets. Movie theater and microwave popcorn are a different story.

What Popcorn Offers a Cat

Popcorn is whole-grain corn puffed with heat. It is mostly starch and fiber with very little fat when air-popped. The Cornell Feline Health Center describes cats as obligate carnivores that rely on nutrients found only in animal products, so popcorn fills no gap in a cat's diet. What it has going for it is that it is light. Many cats are more interested in batting a piece across the floor than eating it.

How Much Popcorn Can a Cat Have?

For a 10-pound adult cat with no known food allergy and no medical condition, 2 or 3 popped pieces is enough, and that adds only a few calories. Tufts lists half a cup of air-popped popcorn at about 15 calories, which is more popcorn than any cat needs. WSAVA advises keeping treats below 10 percent of daily calories, roughly 22 to 25 treat calories a day for a cat of this size, and those few pieces fit inside that with room to spare. Count them as part of the day's food. Kittens, seniors and cats with diabetes, kidney disease, urinary stones, pancreatitis or food allergies should get a veterinarian's opinion first.

How to Serve It

Air-pop the corn with no oil, butter or salt, let it cool and pick out the soft, fully popped pieces. Remove every unpopped kernel and any loose hulls. WSAVA warns against treats with a size or shape that could cause choking, and hard kernels and sharp hulls fit that description. The ASPCA game day guide also says popcorn for pets should be served without seasoning or butter.

Buttered and salted popcorn is the version to avoid. The ASPCA warns that salty foods can cause thirst, vomiting and, in large amounts, tremors and seizures, and movie theater popcorn is heavy in both salt and fat. Microwave popcorn bags usually include salt and oil. Cheese, ranch and garlic popcorn seasonings often contain onion or garlic powder, and the Merck Veterinary Manual names cats as the species most susceptible to onion and garlic poisoning. Caramel corn and kettle corn are coated in sugar. Chocolate-drizzled popcorn brings chocolate, which the ASPCA lists as toxic to pets.

If your cat has a medical condition or eats a prescription diet, ask your veterinarian before offering popcorn.

Common Questions

Can cats eat buttered popcorn?

Cats should not eat buttered popcorn. The butter adds fat and the topping is usually salted, and the ASPCA warns that salty foods can cause thirst and vomiting and, in large amounts, tremors and seizures in pets. Movie theater popcorn is especially heavy in both. If your cat stole a few buttered pieces, offer water and watch for stomach upset. Plain air-popped pieces are the only version to share.

Can cats choke on popcorn?

Yes, popcorn can be a choking risk, mainly from unpopped kernels and the thin hulls that stick in the throat. WSAVA advises against any treat with a size or shape that could cause choking. If you share popcorn, pick out soft, fully popped pieces and remove every kernel and loose hull. Keep the bowl out of reach so your cat cannot help itself to the bottom.

Can kittens eat popcorn?

It is better not to give popcorn to kittens. They are small, their throats are narrow, and hulls and kernels are a choking concern. They also need every bite to come from a complete kitten food while they grow. If a kitten swipes a soft popped piece, there is no need to panic, but keep the bowl out of reach.

Can cats eat microwave popcorn?

Microwave popcorn is not a good choice for cats. Most bags are made with salt, oil and butter flavoring, and some include cheese or other seasonings that may contain onion or garlic powder. The ASPCA warns against salty foods for pets. If you want to share, air-pop a small batch with nothing on it and give your cat two or three soft pieces.

Why does my cat like popcorn?

Many cats like popcorn because it is light and moves when they bat it, so it turns into a toy. Others are drawn to the smell of butter or salt. A cat's interest does not mean it needs popcorn, since Cornell describes cats as obligate carnivores. Letting your cat chase a plain air-popped piece is fine, but do not leave buttered popcorn within reach.
