FAQ: Common Questions About Cat Vomiting

1. Understanding Vomiting in Cats

Vomiting in cats is a common occurrence, but frequent or excessive vomiting is a cause for concern. It’s essential to distinguish between occasional vomiting and chronic vomiting. Occasional vomiting might be due to something simple, like eating too fast, but chronic vomiting can indicate a more serious underlying issue.

The act of vomiting involves the forceful expulsion of stomach contents, often preceded by signs such as drooling, lip-licking, and abdominal contractions. Understanding the difference between vomiting and regurgitation is also important. Regurgitation is a passive process where undigested food is expelled without any abdominal effort.

Vomiting can be triggered by various factors, including dietary indiscretions, infections, systemic diseases, and even stress. Observing your cat’s vomiting patterns and any accompanying symptoms can provide valuable information for your veterinarian.

2. Common Causes of Frequent Vomiting

Many factors can contribute to frequent vomiting in cats. Identifying the cause is the first step in providing appropriate care. Some common causes include:

Hairballs: Cats groom themselves frequently, ingesting hair that can accumulate in the stomach. Hairballs are a common cause of vomiting, especially in long-haired breeds. Regular grooming can help reduce the incidence of hairballs.

Dietary Indiscretion: Eating spoiled food, garbage, or foreign objects can irritate the stomach and lead to vomiting. Keep garbage cans securely covered and ensure your cat doesn’t have access to potentially harmful substances.
Food Allergies or Intolerances: Some cats are sensitive to certain ingredients in their food, such as grains, artificial additives, or specific proteins. This can lead to gastrointestinal upset and vomiting.
Infections: Viral, bacterial, or parasitic infections can cause inflammation in the digestive tract, resulting in vomiting. Regular vaccinations and deworming can help protect your cat from these infections.
Inflammatory Bowel Disease (IBD): This chronic condition involves inflammation of the digestive tract, leading to vomiting, diarrhea, and weight loss.
Kidney Disease: As kidney function declines, toxins can build up in the bloodstream, leading to nausea and vomiting.
Hyperthyroidism: An overactive thyroid gland can cause various symptoms, including increased appetite, weight loss, and vomiting.
Pancreatitis: Inflammation of the pancreas can disrupt digestion and cause vomiting, abdominal pain, and loss of appetite.
Foreign Bodies: Swallowing non-food items, such as string, toys, or bones, can cause an obstruction in the digestive tract, leading to persistent vomiting.
Toxins: Exposure to toxic substances, such as household cleaners, pesticides, or certain plants, can cause severe vomiting.

3. Dietary Issues and Vomiting

Diet plays a significant role in your cat’s digestive health. Dietary indiscretions, allergies, and intolerances are common triggers for vomiting.

Food Allergies: Some cats develop allergic reactions to specific ingredients in their food, such as beef, fish, or dairy. Symptoms may include vomiting, diarrhea, skin irritation, and itching. A food elimination trial, guided by your veterinarian, can help identify the offending allergen.
Food Intolerances: Intolerances are different from allergies, as they don’t involve the immune system. However, they can still cause digestive upset, including vomiting. Common culprits include artificial additives, preservatives, and grains.

Alt text: A variety of cat food options designed for sensitive stomachs and specific dietary needs, aiding in managing vomiting and digestive issues.

Sudden Diet Changes: Changing your cat’s food abruptly can disrupt the balance of bacteria in the gut, leading to vomiting and diarrhea. Always transition to a new food gradually over several days.
Overeating: Eating too much, too quickly can overload the stomach and trigger vomiting. Provide smaller, more frequent meals to prevent overeating.
Spoiled Food: Always ensure your cat’s food is fresh and hasn’t expired. Bacteria in spoiled food can cause severe gastrointestinal upset.

4. Medical Conditions Causing Vomiting

Various medical conditions can manifest as frequent vomiting. It’s essential to consult with a veterinarian to rule out serious underlying issues.

Kidney Disease: Chronic kidney disease is a common condition in older cats. As kidney function declines, toxins accumulate in the bloodstream, leading to nausea and vomiting.
Hyperthyroidism: This endocrine disorder, common in middle-aged to older cats, involves an overactive thyroid gland. Symptoms include increased appetite, weight loss, hyperactivity, and vomiting.
Pancreatitis: Inflammation of the pancreas can cause severe vomiting, abdominal pain, and loss of appetite.
Inflammatory Bowel Disease (IBD): This chronic inflammatory condition affects the digestive tract, leading to vomiting, diarrhea, weight loss, and abdominal discomfort.
Liver Disease: Various liver conditions, such as hepatitis, liver tumors, and bile duct obstruction, can cause vomiting, jaundice, and loss of appetite.
Diabetes: While less common as a direct cause of vomiting, uncontrolled diabetes can lead to complications like diabetic ketoacidosis, which can cause vomiting.
Cancer: Tumors in the digestive tract or other abdominal organs can cause vomiting, weight loss, and other systemic symptoms.

5. Identifying Types of Vomit

The appearance of your cat’s vomit can provide clues about the potential cause. However, it’s essential to consult with your veterinarian for an accurate diagnosis.

Yellow Vomit: This indicates the presence of bile, which is produced by the liver and stored in the gallbladder. Yellow vomit can suggest an empty stomach or liver-related issues. It can also mean the cat ate something yellow.
Clear Vomit: Clear vomit can result from regurgitation from the esophagus or an empty stomach. It may contain saliva and stomach fluids.
White, Foamy Vomit: Similar to clear vomit, white, foamy vomit often indicates regurgitation or an empty stomach.
Blood in Vomit: The presence of blood, known as hematemesis, is a serious sign. The blood can originate from the mouth, esophagus, or stomach. Fresh, bright red blood suggests a recent injury, while dark, digested blood (coffee-ground appearance) indicates bleeding in the stomach.
Coffee-Ground Vomit: This type of vomit has a dark, granular appearance resembling coffee grounds. It indicates digested blood, suggesting bleeding in the stomach, often due to ulcers.
Brown, Smelly Vomit: This type of vomit can indicate bleeding in the upper gastrointestinal tract or consumption of something brown and foul-smelling.
Undigested Food in Vomit: If the vomit contains undigested food, it suggests that the food never left the stomach. This can occur with food intolerances, allergies, obstructions, or any condition that irritates the upper gastrointestinal tract.

6. When to See a Veterinarian

Knowing when to seek veterinary care for your vomiting cat is crucial. While occasional vomiting might not be a cause for alarm, certain signs warrant immediate attention.

Frequent or Persistent Vomiting: If your cat vomits multiple times a day or for more than 24 hours, it’s essential to consult with a veterinarian.
Blood in Vomit: The presence of blood in the vomit always warrants immediate veterinary attention.
Lethargy or Weakness: If your cat is lethargic, weak, or unresponsive, it could indicate a serious underlying condition.
Abdominal Pain: Signs of abdominal pain include restlessness, hiding, guarding the abdomen, and reluctance to be touched.
Dehydration: Signs of dehydration include dry gums, sunken eyes, and decreased skin elasticity.
Loss of Appetite: If your cat refuses to eat or drink, it’s important to seek veterinary care.
Weight Loss: Unexplained weight loss can indicate a serious underlying condition.
Changes in Behavior: Any sudden or significant changes in behavior, such as increased aggression or hiding, should be evaluated by a veterinarian.
Known Toxin Exposure: If you suspect your cat has ingested a toxic substance, contact your veterinarian or a pet poison helpline immediately.

7. Veterinarian Examination and Testing

A thorough examination by your veterinarian is essential for diagnosing the cause of vomiting. The veterinarian will ask about your cat’s history, diet, and any other symptoms. They will also perform a physical examination, looking for signs such as abdominal pain, masses, foreign bodies, weight loss, and fever.

The initial questions your veterinarian might ask include:

Was the cat exposed to plants and other toxins?
When did the vomiting start?
What is the cat’s normal diet?
Does the cat go outside, and if so does the cat hunt?
What is in the vomit?
Is the cat on medication?
Is there also diarrhea?
Is the cat eating?
When does the vomiting occur (in relation to eating or other activities)?
Is the cat losing weight?
Is the cat drinking a lot or urinating a lot?
Does the cat play with string?

8. Diagnostic Tests: X-rays and Blood Work

If the physical exam suggests an underlying issue, your veterinarian may recommend diagnostic tests, such as abdominal X-rays and blood work.

Abdominal X-rays: X-rays can reveal abnormalities in organ size and shape, foreign bodies, tumors, constipation, and other conditions. They can help rule out obstructions and other structural issues.
Blood Work: Blood work can detect organ dysfunction, endocrine disorders (such as diabetes and hyperthyroidism), and infections. A complete blood count (CBC) assesses red blood cells, white blood cells, and platelets, while a serum chemistry profile evaluates organ function and electrolyte levels. A urinalysis is needed in conjunction with blood work to diagnose conditions like diabetes, kidney disease and urinary tract infections.

Blood work can also give clues about whether an animal has been exposed to some toxins, such as antifreeze. Unfortunately, there are not many easy tests to diagnose toxin exposure. It is often required that the cat’s person knows of potential exposure to the toxin and the presence of classic signs of toxin exposure.

9. Advanced Diagnostics: Barium Study, Ultrasound, and Endoscopy

If initial tests don’t provide a definitive diagnosis, your veterinarian may recommend more advanced imaging techniques, such as a barium study, ultrasound, or endoscopy.

Barium Study: A barium study involves administering barium sulfate, a contrast agent, orally or rectally. X-rays are then taken to track the barium’s movement through the digestive tract. This can help identify obstructions, motility issues, and other abnormalities.
Ultrasound: Abdominal ultrasound uses sound waves to create detailed images of the internal organs. It can help visualize the liver, pancreas, kidneys, and other organs, allowing for the detection of tumors, inflammation, and other abnormalities. Ultrasound can also be used to guide biopsies of different organs.

Endoscopy: Endoscopy involves inserting a flexible tube with a camera and light source into the digestive tract. This allows the veterinarian to visualize the lining of the esophagus, stomach, and upper intestines, looking for inflammation, ulcers, tumors, and foreign bodies. Endoscopy can also be used to collect tissue samples for biopsy.

10. Exploratory Surgery: When Is It Necessary?

In some cases, exploratory surgery may be necessary to diagnose the cause of persistent vomiting. This is especially true when a foreign body is suspected or when other diagnostic tests are inconclusive.

During exploratory surgery, the veterinarian will examine the abdominal organs, looking for abnormalities such as tumors, inflammation, and foreign bodies. Biopsies can be taken of the intestines, stomach, liver, pancreas, and lymph nodes to help diagnose conditions such as inflammatory bowel disease or cancer.

Surgery is preferred over endoscopy by some veterinarians because the whole intestinal tract can be evaluated, as well as different organs in the abdomen. In addition, full thickness and larger intestinal biopsies can be taken during surgery. Furthermore, biopsies of the liver, pancreas, and lymph nodes can be taken.

11. Treatment Options for Vomiting Cats

Treatment for vomiting depends on the underlying cause. Symptomatic therapy, such as fluids and anti-emetics, can provide relief while the underlying issue is addressed.

Symptomatic Therapy: Symptomatic therapy aims to alleviate the symptoms of vomiting, such as nausea and dehydration. This may involve administering fluids, anti-emetics (anti-vomiting medications), and stomach protectants.
Specific Treatments: Specific treatments target the underlying cause of the vomiting. This may involve antibiotics for bacterial infections, anti-inflammatory medications for inflammatory bowel disease, or surgery to remove foreign bodies or tumors.

The treatment for vomiting varies greatly based on the cause, and describing the treatment for each individual cause is beyond the scope of this resource. However, we can give some generalizations for treatment.

12. Fluid Therapy for Dehydration

Dehydration is a common complication of vomiting. Fluid therapy is essential to restore hydration and electrolyte balance.

Subcutaneous Fluids: Subcutaneous fluids are administered under the skin. This is a less invasive method of fluid therapy, suitable for mild to moderate dehydration.
Intravenous Fluids: Intravenous (IV) fluids are administered directly into a vein. This is a more aggressive method of fluid therapy, recommended for severe dehydration or when subcutaneous fluids are not sufficient.

Dehydration is a self-perpetuating problem, meaning that when animals are dehydrated, they don’t feel good and therefore won’t eat or drink and might even vomit more. This makes them more dehydrated, which makes them feel worse and less likely to eat or drink — and then they get more dehydrated.

13. Anti-Vomiting Medications

Anti-emetic medications can help control vomiting and improve your cat’s comfort.

Maropitant (Cerenia): Maropitant is a commonly used anti-emetic that blocks the receptors in the brain that trigger vomiting.
Ondansetron (Zofran): Ondansetron is another effective anti-emetic that is often used in cases of severe vomiting.
Metoclopramide (Reglan): Metoclopramide is a less commonly used anti-emetic that can also help promote stomach emptying.

Another common therapy for most kinds of vomiting is giving an anti-emetic (anti-vomiting) medication, which can help stop the vomiting and thus decrease fluid loss. These medicines can also help relieve abdominal discomfort and make the cat more prone to eating. Sometimes, stomach protectants such as Pepcid or sucralfate might be indicated, but the helpfulness of these is up for debate. They typically do not cause any harm though. If the anti-emetics do not provide adequate pain control, a pain medication might be added to the cat’s treatment plan.

14. Dietary Changes as Treatment

Dietary changes are often necessary to manage vomiting, especially in cases of food allergies, intolerances, or inflammatory bowel disease.

Easily Digestible Diets: These diets are formulated to be gentle on the digestive system and are often recommended for cats with acute vomiting. Examples include Royal Canin Gastrointestinal High Energy cat food and Hill’s ID cat food.
Limited-Ingredient Diets: These diets contain a limited number of ingredients, reducing the risk of allergic reactions or intolerances.
Novel Protein Diets: These diets contain a protein source that your cat has never been exposed to before, such as rabbit or venison.
Hydrolyzed Protein Diets: These diets contain proteins that have been broken down into smaller pieces, making them less likely to trigger an allergic reaction.

For both chronic and acutely vomiting cats, one of the most important treatments is dietary change. If your cat has an acute case of vomiting, this might involve a temporary change to an easily digestible diet, such as Royal Canin Gastrointestinal High Energy cat food, Hill’s ID cat food, or a bland human food such as meat-flavored baby food (with no onion or garlic powder added) or boiled chicken. Keep in mind that chicken and baby foods are not complete diets for cats and therefore should only be used for a few days. For cats with chronic vomiting, a diet change can be therapeutic as well as diagnostic.

15. Prednisone Use: Benefits and Risks

Prednisone is a corticosteroid medication that can be used to treat inflammatory conditions, such as inflammatory bowel disease. However, it has potential side effects and should only be used under the guidance of a veterinarian.

Benefits: Prednisone can reduce inflammation in the digestive tract, helping to control vomiting and diarrhea.
Risks: Prednisone can cause increased thirst, increased urination, increased appetite, weight gain, and a weakened immune system. It can also worsen certain conditions, such as diabetes and kidney disease.

Inflammatory bowel disease might be the cause of vomiting in some cats. The treatment for inflammatory bowel disease often involves the medication prednisone. We don’t recommend that you try prednisone on your cat without any diagnostics being done because prednisone has a lot of side effects, including an increase in thirst, an increase in urination, a weaker immune system, and weak muscles. Giving a cat prednisone can also make some causes of vomiting (such as pancreatitis, diabetes, and kidney disease) worse. However, if your cat’s blood work and X-rays are normal and you do not wish to pursue further diagnostics, a trial of prednisone could be considered. You’ll want to have a thorough discussion with your veterinarian about the risks.

16. Home Care and Prevention Tips

In addition to veterinary care, there are several steps you can take at home to help manage your cat’s vomiting and prevent future episodes.

Provide Fresh Water: Ensure your cat always has access to fresh, clean water to prevent dehydration.
Feed Small, Frequent Meals: Feeding smaller, more frequent meals can help prevent overeating and reduce the risk of vomiting.
Avoid Sudden Diet Changes: Always transition to a new food gradually over several days.
Keep Garbage Secure: Secure garbage cans to prevent your cat from accessing potentially harmful substances.
Groom Regularly: Regular grooming can help reduce hairballs, a common cause of vomiting in cats.
Monitor for Toxin Exposure: Be aware of potential toxins in your home, such as household cleaners, pesticides, and poisonous plants.
Provide a Stress-Free Environment: Stress can contribute to vomiting in some cats. Provide a safe, comfortable, and enriching environment to minimize stress.
