Causes and Solutions for Cat Regurgitation of Cat Food

If you live with a cat, you have surely noticed that they vomit quite often.

You might see them eating their cat food with gusto, only to have them look distressed and regurgitate it a moment later. Or perhaps you’ve come home to find a pile of vomit on the sofa.

We often hear that "cats just vomit a lot," but why do they regurgitate their food? In this article, I’d like to explore the reasons behind this behavior and discuss some ways to prevent it.

What is "regurgitation" in cats?

It is true that cats vomit frequently. However, it’s always worrying to see them looking so distressed while they heave.

What happens most often is "regurgitation" during or shortly after a meal. Sometimes they vomit up dry food that is almost entirely undigested.

In this case, the food has accumulated in the esophagus and has not yet reached the stomach, which is why it comes back up undigested. Regurgitation in cats is not always a sign of illness; for them, it is more like a normal physiological phenomenon.

Reasons why cats regurgitate food

There are specific reasons why cats regurgitate their food, related to both their instincts and their physical structure. Let’s take a closer look.

Swallowing prey whole

Cats are carnivorous animals that originally lived by hunting. When they catch small animals like mice or birds, they often swallow them whole. Their dental structure is also typical of carnivores, specialized for tearing meat and gulping it down.

They have an instinct to "gulp" their food so other animals won’t steal it, and to "eat quickly" before being attacked by others.

It’s no wonder that eating this way can lead to regurgitation.

Food easily accumulates in the esophagus

Food tends to build up in a cat's esophagus because their esophagus runs straight from the mouth to the stomach, and it takes time for food to reach the bottom.

Because humans walk upright, food entering the mouth travels down the esophagus and quickly reaches the stomach. Cats, however, walk on four legs, so their esophagus is parallel to the ground. As a result, food can get stuck in the esophagus before it ever reaches the stomach.

Furthermore, a cat's stomach isn't very large—it's small to allow for their agility. That’s why they end up regurgitating when they swallow too much or swallow everything all at once.

Ways to prevent regurgitation

The causes of regurgitation are the cat's instinct to "gulp and eat quickly" and the "structure of their esophagus," where food can easily get stuck.

Let’s consider some solutions focused on their eating habits and esophageal structure.

Increase the number of meals

If too much time passes between meals, feelings of hunger will cause the cat to "eat too quickly."

Since eating with intensity causes regurgitation, try reducing the amount of food given at one time and increasing the frequency of feedings, or offer small treats to stave off hunger. Using an automatic feeder while you are away is also a great option.

Separate feeding areas for other household cats

If you have multiple cats, competition can sometimes lead to "fast eating." Try separating their feeding areas or feeding them in different rooms.

Change the cat food

Cats do not have the habit of chewing their food well, but larger kibble can be harder to "swallow whole," which may help prevent regurgitation. On the other hand, some kibble may be too large, causing them to regurgitate, so monitor your cat and try a smaller kibble if necessary.

There are also commercially available "easy-digest" or "regurgitation-reducing" foods that are designed to break down quickly in the stomach.

Use elevated bowls

When I spoke with owners struggling with their cats' regurgitation, they found that "using a tall bowl" or "using a bowl stand" was the most effective solution.

As mentioned earlier, food easily accumulates in a cat's esophagus. When they eat with their head down, the esophagus is positioned lower than the stomach, making it easier for food to come back up. This is especially true for cats that gobble their food, causing it to flow backward.

However, using a tall bowl with legs means the cat doesn't have to lower its head, which prevents regurgitation. Using a bowl stand is equally effective.

When to be careful if your cat vomits

Cats vomit even when they are healthy. For example, it is well known that they vomit hairballs that accumulate in their stomach from grooming.

They may also vomit yellow bile or stomach acid if they go too long without eating. You might see them vomit when their food is suddenly changed, but as long as they seem energetic, it is generally not a problem.

However, you should not rub your cat's back just because they seem distressed; this could lead to the danger of aspiration, so just watch over them from nearby. Also, avoid giving them water or food immediately after vomiting, as their upset stomach might be caused by an underlying gastrointestinal issue.

When to see a veterinarian!

Sometimes vomiting is caused by illness. Observing what was vomited and how the cat is acting is very important. Consult a veterinarian immediately in the following situations:

● Vomiting clear liquid or white foam

If they are too hungry, they may vomit stomach acid. If they can eat normally otherwise, it’s usually fine, but if they vomit repeatedly or daily, it could be a sign of accidental ingestion or digestive disease.

● Blood is present

This may indicate irritation of the esophagus or bleeding in the mouth. It can also occur with roundworm infections or the accidental ingestion of foreign objects, so be sure to check the contents of the vomit.

● Vomiting something brownish

This could be due to bleeding caused by an ulcer or tumor. See a veterinarian immediately.

● Accompanied by diarrhea, fever, or tremors

These may be signs of poisoning from food, plants, or chemicals.

● Unable to vomit successfully, or decreased appetite

If a foreign object is stuck in the esophagus, they may be unable to bring it up. Also, if they are only drooling, it could be a sign of hairball disease.

Summary

The reasons why cats regurgitate their food are their instinct to "gulp and eat quickly" and the "esophageal structure" where food easily accumulates. While regurgitation is a normal physiological phenomenon for cats, it’s hard to watch them look so uncomfortable.

"Reducing the amount per meal and increasing the frequency," "separating feeding areas for other household cats," and "switching to food that is harder to gulp or breaks down easily in the stomach" can help prevent regurgitation caused by eating too fast.

As an immediate and effective measure, I highly recommend "using a tall bowl." Since they can eat without looking down, it prevents food from building up in the esophagus. Many owners have found this to be very effective, so please give it a try.
