1. Initial Assessment: Questions Your Vet Will Ask About Cat Vomiting

When your cat starts vomiting, your veterinarian will need detailed information to understand the possible causes. Providing thorough answers to these questions can significantly aid in diagnosis and treatment.

Was the cat exposed to plants and other toxins?
- This helps determine if poisoning is the cause. Exposure to toxic substances can lead to vomiting as the cat’s body tries to expel the harmful material.
When did the vomiting start?
- The timing of the onset is important. Acute vomiting (sudden onset) may suggest different issues than chronic vomiting (long-term, recurring).
What is the cat’s normal diet?
- Understanding the diet helps identify potential food intolerances or allergies. A sudden change in diet can also cause digestive upset.
Does the cat go outside, and if so does the cat hunt?
- Outdoor cats may ingest prey, which can carry parasites or toxins. Hunting also increases the risk of consuming spoiled food.
What is in the vomit?
- The contents of the vomit can provide clues. Undigested food, bile, or blood all suggest different underlying problems.
Is the cat on medication?
- Certain medications can cause vomiting as a side effect. Knowing the cat’s medication history is crucial.
Is there also diarrhea?
- Vomiting and diarrhea together often indicate a gastrointestinal issue, such as an infection or inflammatory condition.
Is the cat eating?
- Changes in appetite can be significant. A cat that stops eating in conjunction with vomiting may have a more serious condition.
When does the vomiting occur (in relation to eating or other activities)?
- The timing of vomiting can be telling. Vomiting immediately after eating might indicate regurgitation or a food intolerance.
Is the cat losing weight?
- Weight loss can indicate a chronic underlying condition, such as inflammatory bowel disease or cancer.
Is the cat drinking a lot or urinating a lot?
- Increased thirst and urination can be signs of diabetes, kidney disease, or hyperthyroidism, all of which can cause vomiting.
Does the cat play with string?
- Cats that ingest string or other linear foreign bodies can develop intestinal obstructions, leading to vomiting.

Based on the answers to these questions, your veterinarian will have a better understanding of which diagnostics, if any, to use.

2. Decoding Vomit: What Different Colors And Consistencies Mean

The appearance of your cat’s vomit can provide valuable clues, though it’s not a definitive diagnosis. Here’s a breakdown of what different vomit characteristics might suggest:

Vomit Characteristics	Possible Causes
Yellow vomit	Bile, liver disease, empty stomach, or ingestion of something yellow
Clear vomit	Regurgitation from the esophagus or empty stomach
White, foamy vomit	Regurgitation from the esophagus or empty stomach
Blood in the vomit	Bleeding from the mouth, esophagus, or stomach
Coffee-ground appearance	Bleeding from the stomach, often associated with ulcers
Brown, smelly vomit	Bleeding in the upper gastrointestinal tract or ingestion of something brown and smelly
Undigested food in the vomit	Food never left the stomach, food intolerances/allergies, obstructions, GI tract irritation

Yellow Vomit: This often contains bile, which can indicate liver issues, especially if it’s frequent. However, it’s also common when a cat vomits on an empty stomach. Sometimes, it simply means your cat ate something yellow.
Clear Vomit: This is often regurgitation, which comes from the esophagus, or it could be stomach fluids if the stomach is empty.
White, Foamy Vomit: Similar to clear vomit, this typically indicates regurgitation from the esophagus or an empty stomach.
Blood in the Vomit: This indicates bleeding in the mouth, esophagus, or stomach. The underlying cause needs to be identified to prevent further blood loss.
Coffee-Ground Appearance: This type suggests bleeding in the stomach, typically caused by ulcers. The dark color results from blood being partially digested.
Brown, Smelly Vomit: This can be due to bleeding in the upper gastrointestinal tract or from eating something brown and foul-smelling.
Undigested Food: This means the food didn’t leave the stomach. This can be due to food intolerances, allergies, obstructions, or general irritation of the upper gastrointestinal tract. The timing of the last meal is crucial here. If a cat hasn’t eaten in a day and vomits undigested food, it strongly suggests an obstruction or motility disorder.

3. Veterinary Examination: What To Expect During A Check-Up

A thorough physical examination by your veterinarian is crucial for diagnosing the cause of your cat’s vomiting. The vet will look for several key indicators:

Abdominal Pain: Palpating the abdomen can reveal areas of tenderness, suggesting inflammation or obstruction.
Masses in the Abdomen or Elsewhere: The vet will check for any abnormal growths or lumps that could indicate tumors or other issues.
Obvious Foreign Body: Examining under the tongue, the vet may find strings or other foreign objects that the cat has ingested.
Evidence of Weight Loss: Weight loss can indicate a chronic condition affecting nutrient absorption or overall health.
Heart Murmur: Heart issues can sometimes contribute to gastrointestinal problems, so the vet will listen for any abnormal heart sounds.
Enlarged Thyroid Gland: An enlarged thyroid can indicate hyperthyroidism, a condition known to cause vomiting.
Fever: A fever suggests an infection or inflammatory process is occurring in the body.

The findings from this examination will help the veterinarian determine which diagnostic tests are necessary. Discover a wealth of veterinary insights and detailed diagnostic guides at FOODS.EDU.VN, ensuring comprehensive care for your feline companion.

4. Diagnostic Tools: X-Rays And Blood Work For Cats

If the physical exam warrants further investigation, abdominal X-rays and blood work, including a urinalysis, are usually the first tests performed.

4.1. Abdominal X-Rays

Abdominal radiographs, or X-rays, can reveal a variety of issues within the abdomen that a physical exam might miss. X-rays can identify:

Abnormalities in Organ Size and Shape: Enlarged or shrunken organs can indicate disease.
Foreign Bodies: X-rays can detect the presence of ingested objects that are causing an obstruction.
Tumors: Growths within the abdomen may be visible on X-rays.
Constipation: Severe constipation can sometimes cause vomiting.
Other Abnormalities: This can include fluid accumulation or structural issues.

4.2. Blood Work and Urinalysis

Blood work and urinalysis are essential for assessing your cat’s overall health. These tests can detect:

Organ Dysfunction: Blood work can identify issues with the liver, kidneys, and pancreas.
Endocrine Disorders: Conditions like diabetes and hyperthyroidism can be diagnosed through blood tests.
Diabetes: Elevated glucose levels in the blood and urine can indicate diabetes.
Kidney Disease: Blood work can reveal elevated kidney values, while urinalysis can detect protein in the urine.
Urinary Tract Infections: Urinalysis can identify the presence of bacteria and inflammatory cells in the urine.
Exposure to Toxins: Blood work can sometimes detect exposure to toxins like antifreeze, though specific tests are often needed and the cat’s history is important.

5. Advanced Diagnostics: Barium Study, Ultrasound, And Endoscopy

When initial tests like X-rays don’t provide a clear diagnosis, more advanced imaging techniques may be necessary. These include barium studies, ultrasounds, and endoscopy.

5.1. Barium Study

A barium study involves administering barium, a contrast agent, to the cat, followed by a series of X-rays. This helps to:

Identify Foreign Objects: Barium can highlight obstructions caused by foreign objects.
Assess Intestinal Motility: The study can reveal issues with the movement of food through the intestines.

5.2. Ultrasound

An abdominal ultrasound uses sound waves to create detailed images of the abdominal organs. Ultrasound can help visualize:

Organ Architecture: Detailed images of the liver, kidneys, pancreas, and other organs.
Sampling Guidance: Ultrasound can guide the collection of tissue samples for biopsy.

5.3. Endoscopy

Endoscopy involves inserting a flexible tube with a camera into the cat’s gastrointestinal tract. This allows the veterinarian to:

Visualize Foreign Objects: Identify and retrieve foreign objects that don’t show up on X-rays.
Examine the GI Tract Lining: Look for abnormalities, inflammation, or ulcers in the stomach and intestines.
Collect Samples: Obtain tissue samples for biopsy to diagnose conditions like inflammatory bowel disease or cancer.

6. Surgical Intervention: Exploratory Surgery For Persistent Vomiting

In cases of persistent vomiting that cannot be controlled with symptomatic treatment, or when there is a strong suspicion of a foreign body, exploratory surgery may be necessary.

6.1. When Is Exploratory Surgery Considered?

Acute Vomiting: Suspicion of a foreign body that needs immediate removal.
Chronic Vomiting: Investigation of intestinal cancer, non-intestinal abdominal disease, or inflammatory bowel disease (IBD).

6.2. How Surgery Helps

Diagnosis and Treatment: Surgery can both identify and resolve the problem, such as removing a foreign object.
Biopsy Collection: If no foreign object is found, biopsies can be taken from the intestines, stomach, liver, pancreas, and lymph nodes to diagnose the underlying issue.
Comprehensive Evaluation: Surgery allows the veterinarian to evaluate the entire intestinal tract and other abdominal organs.

6.3. Surgery vs. Endoscopy

Feature	Surgery	Endoscopy
Evaluation	Whole intestinal tract and abdominal organs can be evaluated.	Limited to the stomach, upper intestines, or colon.
Biopsy Size	Full thickness and larger intestinal biopsies can be taken. Liver, pancreas, and lymph node biopsies can be taken.	Smaller samples, typically representative of the intestines, can be collected.
Cost	More expensive (can cost more than $2,000).	Less expensive (can run up to $1,500).
Invasiveness	More invasive, requiring a longer recovery period (several weeks).	Less invasive, with a recovery period of a few hours to a day.
Diagnostic Ability	Preferred by some vets for its ability to evaluate the entire abdomen and collect larger, more comprehensive samples. Can diagnose conditions like inflammatory bowel disease or a form of cancer.	May provide a representative sample of the intestines to provide a diagnosis and is much less invasive. Can also be used to look for foreign objects in the stomach that do not show up on X-rays and retrieve them.

Many owners opt for symptomatic treatment due to the invasive and costly nature of diagnostic procedures like endoscopy and surgery. However, these decisions should be made in consultation with your veterinarian to fully understand the risks and benefits.

7. Treatment Options: How To Help Your Vomiting Cat

Treatment for vomiting in cats varies widely depending on the underlying cause. Here are some common approaches:

7.1. Fluid Therapy

Administering fluids is a cornerstone of treating vomiting cats. Fluids help to:

Flush the System: Aid in removing toxins and irritants.
Maintain Hydration: Replace fluids lost through vomiting.

Even if the cat isn’t clinically dehydrated, fluids are beneficial. Dehydration can worsen the condition by reducing appetite and increasing vomiting.

7.1.1. Subcutaneous Fluids

Subcutaneous (under the skin) fluids are often used for mild to moderate dehydration.

Advantages: Can be administered at home, less expensive.
Disadvantages: Slower absorption, not effective for severe dehydration.

7.1.2. Intravenous Fluids

Intravenous (IV) fluids are used for severely dehydrated or weak cats.

Advantages: Direct and rapid fluid replacement, allows for greater fluid volume.
Disadvantages: Requires hospitalization, more expensive.

7.2. Anti-Vomiting Medication

Anti-emetics help to control vomiting, reduce fluid loss, and relieve abdominal discomfort. Common anti-emetics include:

Maropitant (Cerenia): A highly effective anti-emetic that targets the vomiting center in the brain.
Metoclopramide: Helps to increase gastric motility and reduce nausea.

Stomach protectants like Pepcid or sucralfate may also be used, although their effectiveness is debated. If anti-emetics don’t provide adequate pain control, a pain medication might be added.

7.3. Dietary Changes

Dietary changes are crucial for managing both acute and chronic vomiting.

7.3.1. Acute Vomiting

A temporary change to an easily digestible diet can help. Options include:

Prescription Diets: Royal Canin Gastrointestinal High Energy, Hill’s i/d.
Bland Human Food: Meat-flavored baby food (without onion or garlic powder), boiled chicken.

These foods should only be used for a few days, as they are not nutritionally complete.

7.3.2. Chronic Vomiting

Diet changes can be both therapeutic and diagnostic. A diet trial involves switching to a new food for several weeks to see if it controls the vomiting. Consider:

Prescription Diets: Limited-ingredient or hypoallergenic diets.
Novel Protein Diets: Foods with protein sources the cat hasn’t eaten before (e.g., duck, venison).

7.4. Prednisone

Prednisone, a corticosteroid, is often used to treat inflammatory bowel disease (IBD). However, it should only be used after thorough diagnostics due to its potential side effects.

Side Effects: Increased thirst and urination, weakened immune system, muscle weakness.
Contraindications: Can worsen conditions like pancreatitis, diabetes, and kidney disease.

If blood work and X-rays are normal, a trial of prednisone may be considered after discussing the risks with your veterinarian.

8. Preventive Measures: How to Minimize Cat Vomiting

While it’s not always possible to prevent vomiting, here are some strategies to minimize the likelihood:

Regular Vet Check-ups: Early detection and management of underlying health issues.
Controlled Diet: Stick to high-quality, age-appropriate cat food.
Avoid Sudden Diet Changes: Introduce new foods gradually to prevent digestive upset.
Hairball Management: Regular grooming and hairball remedies can reduce hairball-related vomiting.
Safe Environment: Keep toxins, medications, and small objects out of reach.
Slow Feeding: If your cat eats too quickly, use a slow-feeder bowl to prevent vomiting.
Monitor Outdoor Activity: Supervise outdoor cats to prevent ingestion of toxins or prey.
Water Availability: Ensure constant access to fresh, clean water to prevent dehydration.

9. Understanding The Root Causes Of Cat Vomiting

To effectively address the issue of cat vomiting, it’s crucial to understand the various underlying causes. Here’s a comprehensive overview:

9.1. Dietary Issues

Food Allergies/Intolerances: Just like humans, cats can develop allergies or intolerances to certain ingredients in their food. Common allergens include beef, dairy, and wheat.
- Symptoms: Vomiting, diarrhea, skin irritation, and excessive grooming.
- Management: A veterinarian can help identify the specific allergen through an elimination diet. Once identified, the cat should be switched to a diet that avoids the allergen.
Sudden Diet Changes: Abrupt changes in diet can disrupt the balance of gut bacteria, leading to digestive upset.
- Symptoms: Vomiting, diarrhea, loss of appetite.
- Management: Introduce new foods gradually over a period of 7-10 days. Start by mixing a small amount of the new food with the old food, gradually increasing the proportion of the new food each day.
Eating Too Quickly: Some cats tend to gulp down their food, which can cause them to vomit shortly after eating.
- Symptoms: Vomiting immediately after eating, often with undigested food.
- Management: Use a slow-feeder bowl to slow down the eating process. Alternatively, divide the cat’s daily ration into several small meals.
Spoiled Food: Eating food that has gone bad can cause vomiting and diarrhea.
- Symptoms: Vomiting, diarrhea, lethargy.
- Management: Always check the expiration date on cat food and store it properly. Discard any uneaten wet food after a few hours.

9.2. Gastrointestinal Issues

Inflammatory Bowel Disease (IBD): IBD is a chronic inflammatory condition that affects the digestive tract.
- Symptoms: Vomiting, diarrhea, weight loss, loss of appetite.
- Management: Treatment typically involves a combination of dietary changes, medication (such as corticosteroids), and probiotics.
Infections: Viral, bacterial, or parasitic infections can cause vomiting and diarrhea.
- Symptoms: Vomiting, diarrhea, fever, loss of appetite.
- Management: Treatment depends on the type of infection. Antibiotics may be used for bacterial infections, while antiviral medications may be used for viral infections. Parasitic infections are typically treated with deworming medications.
Obstructions: Foreign objects, such as hairballs or pieces of toys, can become lodged in the digestive tract, causing an obstruction.
- Symptoms: Vomiting, loss of appetite, abdominal pain.
- Management: Treatment usually involves surgery to remove the obstruction.
Pancreatitis: Inflammation of the pancreas can cause vomiting, diarrhea, and abdominal pain.
- Symptoms: Vomiting, diarrhea, loss of appetite, abdominal pain.
- Management: Treatment typically involves supportive care, such as IV fluids and pain medication.

9.3. Systemic Diseases

Kidney Disease: Kidney disease can cause a build-up of toxins in the blood, which can lead to vomiting.
- Symptoms: Vomiting, loss of appetite, increased thirst and urination.
- Management: Treatment typically involves a combination of dietary changes, medication, and fluid therapy.
Liver Disease: Liver disease can also cause a build-up of toxins in the blood, which can lead to vomiting.
- Symptoms: Vomiting, loss of appetite, jaundice (yellowing of the skin and eyes).
- Management: Treatment depends on the underlying cause of the liver disease.
Hyperthyroidism: An overactive thyroid gland can cause vomiting, weight loss, and increased appetite.
- Symptoms: Vomiting, weight loss, increased appetite, increased thirst and urination.
- Management: Treatment options include medication, radioactive iodine therapy, and surgery.
Diabetes: Diabetes can cause vomiting, increased thirst and urination, and weight loss.
- Symptoms: Vomiting, increased thirst and urination, weight loss, increased appetite.
- Management: Treatment typically involves insulin injections and dietary changes.

9.4. Other Causes

Hairballs: Cats often ingest hair while grooming, which can form hairballs in the stomach.
- Symptoms: Vomiting, gagging, coughing.
- Management: Regular grooming can help reduce the amount of hair that the cat ingests. Hairball remedies, such as special cat foods or lubricating gels, can also help.
Motion Sickness: Some cats experience motion sickness during car rides.
- Symptoms: Vomiting, drooling, anxiety.
- Management: Anti-nausea medications can help prevent motion sickness. It’s also helpful to make the car ride as comfortable as possible by providing a secure carrier and keeping the temperature cool.
Toxins: Ingestion of toxins, such as household cleaners or poisonous plants, can cause vomiting.
- Symptoms: Vomiting, diarrhea, drooling, seizures.
- Management: If you suspect that your cat has ingested a toxin, contact your veterinarian or a pet poison control center immediately.
Medications: Certain medications can cause vomiting as a side effect.
- Symptoms: Vomiting, loss of appetite, lethargy.
- Management: Talk to your veterinarian about any medications that your cat is taking and whether they could be causing the vomiting.
