Are Hiccups in Cats Normal? Causes and When to Worry

By Dr. Zubair Khalid, DVM, MS, PhD · 2026-10-02

Occasional hiccups in cats are normal, especially in kittens and young adults. They usually last a few seconds to a couple of minutes and stop on their own. The question of whether hiccups in cats are normal gets more complicated when the episodes become frequent, start suddenly in an older cat, or come with other signs like coughing, vomiting, or trouble breathing.

This article is educational and is not a substitute for veterinary diagnosis or treatment.

Quick Answer

• A hiccup is a sudden, repeated jerk of the belly and chest, often with a small "hic" sound or a quick head bob. It is caused by a spasm of the diaphragm with closure of the flap over the windpipe.
• Short, occasional hiccup bouts in a playful, eating, normal kitten or adult cat are not a health concern.
• Frequent hiccups in cats, hiccups that last more than a few minutes, or hiccups that appear for the first time in an older cat deserve a veterinary exam.
• Hiccups can be confused with coughing, reverse sneezing, hairballs, or a type of muscle jerk called myoclonus, so the exact look of the episode matters.
• Never give your cat human hiccup remedies, sedatives, or leftover medications. Call your veterinarian or a poison control hotline if you think your cat ate something toxic.

What Hiccups Look Like in Cats

A true hiccup is a reflex. The diaphragm, the sheet of muscle under the lungs, contracts suddenly, and the opening of the windpipe snaps shut. That produces the familiar jerk and sound. In people, the reflex involves signals traveling along nerves in the throat, including the glossopharyngeal nerve [1]. The same basic reflex is thought to occur in cats.

In a cat, you may see:

• A quick, rhythmic jerk of the belly or chest
• A small head bob or a brief stretch of the neck
• A soft "hic" or click, though many cats are silent
• The episode stopping within seconds to a couple of minutes

Kittens get hiccups often. Their eating is fast and messy, they swallow air, and their nervous systems are still maturing. A kitten who hiccups after a meal and then runs off to play is almost certainly fine.

Adult cats hiccup less often than kittens, but an occasional bout is still normal. The pattern to remember is short, infrequent, and harmless.

What Do Hiccups in Cats Mean?

Most of the time, hiccups mean nothing more than a full stomach or a bit of swallowed air. The reflex can be triggered by stomach distension, eating or drinking quickly, or irritation anywhere along the nerve pathway that runs from the throat to the diaphragm.

When hiccups become frequent, last a long time, or show up in a cat who never had them before, they can be a clue to an underlying problem. The table below lists the main categories veterinarians consider.

Some of these causes overlap. A cat with chronic intestinal inflammation may also have reflux, and a cat with kidney disease may twitch because of medication or because of the disease itself. Your veterinarian sorts this out with an exam and testing.

Causes of Hiccups in Cats

Eating and Drinking Habits

This is the most common and most harmless cause. A cat who bolts food, eats dry food too fast, or drinks a lot of water at once swallows air and stretches the stomach. The diaphragm reacts. Splitting meals into smaller portions and using a slow feeder often reduces episodes.

Gastrointestinal Disease

The stomach and intestines sit right next to the diaphragm, so irritation there can trigger the reflex. Chronic inflammation of the colon, called colitis, causes long-term diarrhea and is most often seen in middle-aged cats, and purebreds seem overrepresented [2]. When the large intestine is damaged by illness, parasites, or other causes, diarrhea is often the result [2]. Cats with chronic colitis may also have vomiting, weight loss, and reduced appetite, and hiccups can appear alongside those signs. If your cat has diarrhea with a jelly-like coating, see Cat Diarrhea with Mucus: Causes and When to Worry.

Reflux and Hiatal Changes

Gastroesophageal reflux means stomach acid washes back into the esophagus. In cats, reflux is thought to occur frequently with upper airway obstruction, including in flat-faced breeds [3]. A study of CT scans found that the opening in the diaphragm where the esophagus passes through, called the esophageal hiatus, can differ in size between flat-faced and other cats [3]. Reflux can cause gulping, lip smacking, and hiccup-like spasms after eating.

Respiratory Disease

Coughing is often mistaken for hiccups. A cat with asthma, bronchitis, or pneumonia may have repeated chest jerks that look like hiccups but come with wheezing or a honking cough. If your cat is coughing, read Cat Coughing: When Should You Worry?. Breathing that is fast, labored, or done with an open mouth is an emergency.

Neurologic Causes and Myoclonus

This is the category owners most often miss. Myoclonus is a sudden muscle jerk. In cats, a specific syndrome called spontaneous late-onset myoclonic epilepsy causes head jerking in older cats. In a study of 15 cats, all were older, with a median age of 13.2 years, and every cat had spontaneous jerking of the head, with some also involving the front legs or the whole body [4]. The jerking got more frequent over time in about half the cats, and the median time from the first episode to veterinary presentation was 5.5 months [4]. Two of the 15 cats also had generalized seizures [4].

This matters because owners often describe these jerks as hiccups. If an older cat develops new, repeated head or body jerks, that is not a simple hiccup and needs a neurologic workup.

Medication Reactions

Some drugs can cause twitching. Two cats with stage 2 chronic kidney disease and a history of seizures developed intermittent short jerks of the head after receiving gabapentin at doses of 11.8 to 16.4 mg/kg before veterinary visits [5]. These were the first published reports of this possible effect in cats, and the risk factors mirrored those seen in people [5]. Another report described a cat who developed muscle jerks, rigidity, and urinary retention after morphine was given near the spinal cord, and the jerking resolved with treatment that included midazolam [6]. If jerking starts after a new medication, call your veterinarian. Do not stop or change a prescription on your own.

Toxins

Sudden twitching, drooling, wobbling, or vomiting after your cat gets into something it should not have is an emergency. Bring the packaging or a photo of the substance with you.

Red Flags: When Hiccups in Cats Are an Emergency

Go to an emergency clinic now if your cat has any of these:

• Open-mouth breathing, blue gums, or obvious struggle to breathe
• Collapse, unresponsiveness, or a seizure
• Continuous jerking that will not stop
• Twitching along with drooling, vomiting, or wobbling after possible toxin exposure
• A swollen, painful belly or repeated unproductive retching

Call your veterinarian the same day if you see:

• Hiccups that last more than a few minutes or keep restarting
• New hiccups in a cat older than 8 years
• Hiccups with vomiting, diarrhea, weight loss, or poor appetite
• Hiccups with coughing, wheezing, or a change in breathing
• Jerking that is getting more frequent over weeks or months
• Any new twitching after starting a medication

Schedule a routine visit if the hiccups are mild but have been happening more often than before, or if you are not sure whether the episodes are hiccups or something else.

What You Can Do at Home While You Wait

You cannot cure a hiccup reflex, but you can reduce triggers and gather good information.

• Slow down meals. Use a shallow plate, a slow feeder, or several small meals instead of one large one.
• Keep the food and water bowls clean and place them away from litter boxes.
• Note the timing. Write down when episodes happen, how long they last, and what the cat was doing just before.
• Record a video. A 10-second phone video of the episode is one of the most useful things you can bring to an appointment.
• Keep a simple log of appetite, vomiting, diarrhea, coughing, and energy level.
• Do not give human medications, sedatives, or supplements for hiccups.
• Keep the cat indoors and away from string, plants, and human foods that can cause harm.

If your cat is hiding more than usual along with the hiccups, that can be an early sign of discomfort. See Cat Hiding: When to Worry and When It's Normal Cat Behavior. If vomiting is part of the picture, see Why Is My Cat Vomiting? Common Causes and Red Flags.

What Your Veterinarian Will Check

Your veterinarian will start with a full history. Expect questions about diet, eating speed, vomiting, diarrhea, coughing, breathing, medications, and how the episodes look. The video you recorded helps here.

The physical exam focuses on the mouth and throat, the belly, the heart and lungs, and a neurologic check. Your vet will watch your cat move and may test reflexes.

Testing depends on what the exam suggests. For suspected gastrointestinal disease, your veterinarian may ask detailed questions, do a physical exam, try specific diets, and run blood, urine, and fecal tests, plus abdominal x-rays or ultrasound, endoscopy, or biopsies if needed [2]. For suspected reflux or airway problems, imaging of the chest and throat may be recommended [3]. For suspected myoclonus or epilepsy, advanced imaging of the brain is often part of the workup, and in one case series about half of the cats had advanced imaging [4].

Treatment depends on the cause. Diet changes, anti-nausea drugs, acid reducers, parasite treatment, or anti-seizure medication may all be options. Your veterinarian calculates any medication dose from your cat's weight and health status.

Prevention and Monitoring

You cannot prevent every hiccup, but you can lower the odds of the harmless kind and catch the serious kind early.

• Feed smaller, more frequent meals and slow down fast eaters.
• Keep up with routine wellness visits, especially for cats over 8 years old.
• Brush your cat regularly to reduce hairball and grooming-related throat irritation.
• Watch for changes in drinking and urination. If your cat is drinking more and urinating more, see Cat Urinating Frequently: Causes and When to Worry.
• Track episodes over time. A pattern of increasing frequency is a reason to call your vet, even if each episode looks mild.
• Tell your veterinarian about every medication and supplement your cat receives, including ones given before travel or vet visits.

Limitations and When to Contact a Veterinarian

This article cannot tell you what is causing your cat's hiccups. Only a veterinarian who examines your cat can do that. Individual cases need a veterinarian.

Use these timing rules:

• Emergency now: trouble breathing, collapse, seizure, continuous jerking, or suspected toxin exposure.
• Same day: new hiccups in an older cat, episodes lasting more than a few minutes, hiccups with vomiting, diarrhea, weight loss, or coughing, or new twitching after a medication.
• Routine visit: mild hiccups that are becoming more frequent, or episodes you cannot clearly identify as hiccups.

When in doubt, call your veterinary clinic and describe what you see. A short phone call often settles whether your cat needs to be seen right away.

Frequently Asked Questions

Is it normal for kittens to get hiccups?

Yes, hiccups are common and normal in kittens. They often happen after fast eating or drinking, and the episodes are short. If a kitten hiccups constantly, stops eating, or has trouble breathing, call your veterinarian.

What do hiccups in cats mean when they happen every day?

Daily hiccups are more likely to have an underlying trigger than occasional ones. Common triggers include fast eating, reflux, and stomach or intestinal irritation. Your veterinarian can help sort out which one applies to your cat.

Can hiccups in older cats be a sign of something serious?

Yes, they can. New, repeated jerking in an older cat may be myoclonus or a seizure disorder instead of true hiccups. In one case series, all affected cats were older, and the jerking tended to become more frequent over time [4]. A neurologic exam is the right next step.

How can I tell hiccups apart from a cough or a hairball?

Hiccups are rhythmic, short, and usually silent or make a small click. Coughs are louder, often end with a gag or a swallow, and may bring up foam. Hairball episodes involve retching and a stretched-out neck. A video helps your vet tell the difference.

Should I try to stop my cat's hiccups at home?

No. There is no safe home remedy for cat hiccups, and human treatments can be harmful. If the episodes are short and your cat is otherwise normal, simply wait and note what happened. If they are frequent or come with other signs, call your veterinarian.
