# How to Stop Your Cat Throwing Up: Causes and Next Steps Vomiting in cats is the forceful ejection of stomach or upper intestinal contents through the mouth, usually after drooling, swallowing, retching, and hard belly contractions [1]. To stop my cat from throwing up, the first step is figuring out which problem you are actually seeing, because a hairball, a regurgitated meal, and true vomiting need very different responses. Some causes are minor and manageable at home, and others need a veterinarian the same day. This article is educational and is not a substitute for veterinary diagnosis or treatment. ## Quick Answer - A hairball is usually a tubular clump of fur, and frequent hairballs are not normal, so see your veterinarian if they keep happening or your cat vomits repeatedly [1]. - Food that comes up in a soft, undigested tube right after eating is often regurgitation, not vomiting, and it points to eating too fast or a food issue. - True vomiting involves retching, drooling, and belly contractions, and it has a long list of possible causes, from stomach disease to kidney or liver failure, pancreatitis, poisons, parasites, infections, drugs, foreign objects, food allergy, and tumors [1]. - Never give your cat human anti-nausea medicine or any prescription drug without veterinary guidance, because some are toxic to cats and others can hide a serious problem. - Call your veterinarian if vomiting repeats, lasts more than a day, or comes with lethargy, pain, or refusal to eat. ## What Throwing Up Looks Like and What Is Normal Owners use "throwing up" for three different events. Knowing which one you saw changes everything. **Regurgitation** is passive. Food or fluid slides back up with little effort, often within minutes of eating. The material looks like a soft tube of undigested food, sometimes still in the shape of the kibble. There is no retching and no big drama. **True vomiting** is active. Your cat drools, swallows repeatedly, retches, and the belly muscles and diaphragm contract forcefully to push contents out [1]. The material may be digested food, yellow bile, foam, or fluid. **Hairballs** are a specific type of vomit. They are clumps of swallowed fur, often shaped like a cigar. An occasional hairball in a longhaired cat is common. Frequent hairballs are not, and they can signal that something more serious than a hairball is to blame [1]. Normal cats vomit occasionally, but "normal" does not mean daily. If your cat throws up more than a couple of times a month, or if the episodes are getting closer together, that is a pattern worth investigating. For a deeper look at causes, see [Why Is My Cat Vomiting? Common Causes and Red Flags](/knowledge/veterinary-medicine/symptom-guides/why-is-my-cat-vomiting). ## Main Causes of Vomiting in Cats The list of causes is long, and many of them look identical from the outside. Vomiting can come from digestive system disease, kidney or liver failure, pancreatitis, or nervous system disorders [1]. Other causes include poisons, insect stings or snake bites, internal parasites such as heartworm disease, infections, inflammation, drugs, swallowed foreign objects, food allergy, and tumors [1]. | Cause | Typical clues | How urgent | |---|---|---| | Hairball | Tubular clump of fur, occasional, cat otherwise bright | Routine if rare, vet visit if frequent [1] | | Eating too fast | Food comes up soon after meals, undigested, no retching | Manageable at home, vet if it continues | | Food intolerance or allergy | Vomiting after a specific food, sometimes with itching or soft stool | Routine visit for a diet plan | | Hairball prevention diet or treat | Owner recently changed food or added treats | Routine, review the diet | | Foreign object | Sudden vomiting, not eating, hiding, sometimes drooling | Emergency, especially if repeated | | Poison or toxin | Known or suspected exposure, sudden vomiting, drooling, wobbliness | Emergency now | | Parasites or infection | Vomiting with diarrhea, weight loss, poor coat | Same-day to routine visit | | Kidney or liver failure | Vomiting with increased drinking, weight loss, bad breath | Same-day visit | | Pancreatitis | Vomiting with belly pain, hunched posture, no appetite | Same-day visit | | Tumor or mass | Slow onset, weight loss, changing appetite | Prompt veterinary workup | One practical point about hairballs. You can limit how much hair your cat swallows by brushing frequently to remove loose fur, and some commercial diets and treats are made to help prevent hairball formation [1]. In severe cases, surgery may be needed to remove a hairball [1]. That last fact is why repeated hairballs deserve a real exam instead of another round of brushing. ## How to Stop My Cat From Throwing Up After Eating If the food comes back up shortly after a meal and your cat seems fine afterward, you are likely dealing with fast eating or regurgitation. Try these steps. **Slow the meal down.** Spread the food on a plate or use a shallow puzzle feeder so your cat cannot gulp. Multiple small meals beat one large one. **Raise the bowl slightly.** A small elevation can help some cats swallow more comfortably. Keep it low enough that your cat is not reaching up. **Separate meals in a multi-cat home.** Competition makes cats eat fast. Feed cats in different rooms and pick up leftovers. **Warm the food slightly.** A gentle warm-up makes food more appealing and can slow frantic eating for some cats. **Keep a food and symptom log.** Note the brand, flavor, amount, and time of each meal, plus when the vomiting happens. This log is the single most useful thing you can bring to a veterinary visit. If your cat vomits undigested food repeatedly, read [Cat Vomiting Undigested Food: Why It Happens and What to Do](/knowledge/veterinary-medicine/digestive-and-urinary-care/cat-vomiting-undigested-food-why-what-to-do) for more detail on this specific pattern. ## How to Stop My Cat From Throwing Up Hairballs Hairballs form when swallowed fur clumps in the stomach instead of passing through the digestive tract. The fix is less hair in, more hair out. **Brush daily.** This is the most effective home step, and frequent brushing removes loose fur before your cat grooms it off [1]. **Consider a hairball formula diet or treat.** Some commercial cat diets and treats are formulated to help prevent hairball formation [1]. **Ask about lubricants.** If needed, medications such as mineral oil can be given to help cats pass hair through the digestive tract [1]. Do not start this on your own, because the dose and product matter and your veterinarian should decide if it is appropriate for your cat. **Watch the pattern.** See your veterinarian if your cat has frequent hairballs or vomits repeatedly, because something more serious than a hairball could be to blame [1]. ## Red Flags That Make It an Emergency Go to an emergency clinic now if you see any of these. - Repeated vomiting in a short period, especially more than a few times in a day - A known or suspected poisoning, such as lily, onion, acetaminophen, or acetylsalicylic acid exposure - Vomiting with a bloated, painful, or hard belly - Vomiting blood, or material that looks like coffee grounds - Collapse, weakness, wobbliness, or trouble breathing - Straining to vomit with nothing coming up - Vomiting after swallowing string, ribbon, a toy, or any object - A cat that is not eating or drinking and is hiding For poison exposure, call your veterinarian or a pet poison hotline right away. Do not wait to see if symptoms appear. ## Safe Things You Can Do at Home While Waiting Home care is about comfort and information, not treatment. Do these things while you arrange a veterinary visit. **Withhold food briefly, not water.** A short fast of a few hours can settle a mildly upset stomach, but never restrict water. If your cat is a kitten, diabetic, or on medication, skip the fast and call your veterinarian. **Offer small amounts of bland food when ready.** A tablespoon of plain cooked chicken or a veterinary bland diet, offered in small portions, is a reasonable restart for many adult cats. If your cat vomits again, stop and call. **Keep your cat indoors and quiet.** Stress and activity can trigger more vomiting. **Collect a sample.** Put the vomit in a sealed bag or container and photograph it. Color, contents, and presence of hair or foreign material all help your veterinarian. **Do not give human medicines.** Never give your cat anti-nausea drugs, pain relievers, or antacids from your cabinet. Some are toxic to cats, and others can mask a serious problem. **Do not try to make your cat vomit.** Inducing vomiting is a medical procedure. In cats it is difficult and often fails, and it is only appropriate for certain toxins under veterinary direction [2][3]. ## What Your Veterinarian Will Check and Test Your veterinarian will start with a full history, including diet, hairball frequency, possible exposures, and any drugs or supplements. Then comes a physical exam, including weight, hydration, belly palpation, and a look at the mouth and teeth. Testing usually depends on the story but often includes blood work to check organ function, a fecal test for parasites, and imaging such as X-rays or ultrasound if a foreign object or mass is suspected. Because vomiting has so many causes, from kidney or liver failure to pancreatitis, infections, and tumors, the workup is often staged instead of one single test [1]. Treatment depends on the cause. If nausea itself needs control, your veterinarian may prescribe an antiemetic. Maropitant is one option with controlled evidence in cats, and in a pooled analysis it reduced the risk of vomiting compared with control [4]. The dose is calculated from your cat's weight and health, so never use a leftover supply from another pet. One warning about anti-nausea drugs. In cats and dogs with a gastrointestinal foreign body obstruction, giving an antiemetic was linked to a longer time from the start of signs to definitive care and a longer hospital stay [5]. If your cat may have swallowed something, tell your veterinarian before any medication is given. ## Prevention and Monitoring Prevention is mostly about diet, hair control, and early detection. **Feed a consistent, appropriate diet.** Sudden food changes cause upset in many cats. Transition over 7 to 10 days if you switch brands or formulas. If your cat vomits on a specific food, ask your veterinarian about a limited ingredient or prescription diet instead of guessing. **Control hair.** Daily brushing, plus a hairball formula diet or treat if your veterinarian agrees, reduces the fur load [1]. **Keep toxins and small objects out of reach.** Lilies, human medications, string, ribbon, and small toys are common culprits. **Track weight.** A baby scale or regular veterinary weigh-ins catch slow weight loss that vomiting can cause. **Know your cat's baseline.** How often does your cat normally vomit? If the answer changes, that is your signal to call. **Schedule routine exams.** Annual visits for adult cats and twice yearly for seniors catch kidney, liver, and dental problems before vomiting starts. ## Limitations and When to Contact a Veterinarian This article cannot tell you what is wrong with your individual cat. Only a veterinarian who examines your cat can do that, and individual cases always need professional evaluation. **Contact your veterinarian the same day if:** your cat vomits more than twice in 24 hours, vomits for more than a day, has frequent hairballs, stops eating, seems painful, or has diarrhea along with the vomiting. **Go to an emergency clinic now if:** you see repeated vomiting, a suspected poisoning, blood in the vomit, a swollen or painful belly, collapse, trouble breathing, or a cat that is straining to vomit with nothing coming up. **Schedule a routine visit if:** your cat vomits occasionally but is otherwise bright, or if you want to review diet, hairball control, and a monitoring plan. If you are unsure which category fits, call your veterinary clinic and describe what you saw. A phone call is free and can save your cat a lot of discomfort. ## Frequently Asked Questions ### Should I feed my cat after it throws up? For most adult cats, a short pause of a few hours followed by small bland meals is reasonable. If your cat is a kitten, diabetic, or on medication, call your veterinarian before withholding food. If vomiting returns after eating, stop and seek care. ### Can I give my cat human anti-nausea medicine? No. Never give human anti-nausea drugs, pain relievers, or antacids to a cat without veterinary direction. Some are toxic, and others can hide a serious problem like a foreign object or organ failure. ### How do I know if it is a hairball or something worse? A hairball is a clump of fur, and your cat usually acts normal right after. Frequent hairballs or repeated vomiting are reasons to see your veterinarian, because something more serious than a hairball could be to blame [1]. ### What food is best for a cat that throws up? There is no single best food. The right choice depends on the cause, so ask your veterinarian about a limited ingredient, hairball formula, or prescription diet based on your cat's exam and history. Some commercial diets and treats are made to help prevent hairball formation [1]. ### Can my cat vomit from stress or a new environment? Yes, stress and sudden changes can upset a cat's stomach, but stress is a diagnosis of exclusion. If vomiting continues, or comes with lethargy, weight loss, or not eating, have your cat examined to rule out medical causes. ## Related Articles - [Why Is My Cat Vomiting?
