If our cat vomits repeatedly, it's easy to think, "It must be hairballs again." However, depending on the frequency and pattern of vomiting, there are cases where internal medicine causes need to be confirmed. If you are considering a cat vomiting examination in Busan, we recommend checking the cause at an animal medical center with a dedicated cat treatment space and an internal medicine interdepartmental consultation system.


In Busan, How to Choose the Right Hospital for Cat Vomiting Examination?

Cats tend to vomit more frequently than dogs, but "vomiting frequently" and "normal vomiting" are entirely different matters. Repeated vomiting can be a signal of various internal medicine diseases such as digestive disorders, kidney disease, hyperthyroidism, and triaditis, and the types of necessary tests vary depending on the color, frequency, and accompanying symptoms of the vomit.

A single episode of vomiting can be observed for a while. However, according to My Pet Life data, if repeated vomiting, decreased appetite, vomit mixed with blood, or abdominal swelling appear, it is recommended to visit the hospital promptly. Before visiting, taking photos of the vomit can help with more accurate diagnosis.

When selecting an animal hospital in Busan for cat vomiting examination, it is recommended to also check whether there is a dedicated cat treatment space and internal medicine departmental examination system.

In short: If there is repeated vomiting or abnormal signals, a cause examination is more important than "waiting and seeing."


What Causes Should Be Suspected When Cats Vomit Repeatedly?

Repeated vomiting can be a signal of various internal medicine diseases rather than simple indigestion. Refer to the table below and compare it with our pet's condition.

Suspected Disease

Main Characteristics

Required Tests

Gastritis/Chronic Gastrointestinal Inflammation

Fasting yellow liquid vomit, vomiting after meals

Blood test, abdominal ultrasound

Inflammatory Bowel Disease (IBD)

Chronic repeated vomiting, weight loss

Ultrasound, tissue biopsy

Triaditis

Combined vomiting, loss of appetite, lethargy

Blood test, ultrasound, pancreatitis kit

Hyperthyroidism

Weight loss despite maintained appetite, vomiting

Serum thyroid level test

Kidney and Liver Disease

Vomiting, change in water consumption, lethargy combined

Serum chemistry test, ultrasound

Gastrointestinal Lymphoma

Chronic vomiting, weight loss, mass on palpation

Ultrasound, fine needle aspiration, tissue biopsy

Food Allergy

Repeated vomiting and diarrhea after eating specific food

Dietary trial, blood test

In particular, according to Health Kyunghyang data, triaditis is a complex disease characteristically appearing in cats, referring to a state where inflammatory bowel disease, cholangiohepatitis, and pancreatitis occur simultaneously. When repeated vomiting and loss of appetite appear together, complex tests including blood tests, abdominal ultrasound, and pancreatitis kits are necessary to differentiate triaditis.

Additionally, according to Daily Vet reports, in cases of chronic vomiting in cats, it is recommended to confirm bowel wall thickness through ultrasound examination, and if necessary, perform full-thickness biopsy and tissue examination to differentiate IBD and lymphoma. It is difficult to distinguish pathological causes by vomit color alone, so judgment based on age, underlying diseases, and accompanying symptoms is important.


24H UN animal medical center's Approach to Cat Vomiting Diagnosis

A stepwise examination approach is important to identify the cause of cat vomiting. As guided in materials from Konkuk University Veterinary Medical Teaching Hospital, the basic principle for diagnosing internal medicine vomiting in cats is to perform blood tests, urinalysis, radiography, ultrasound, and endoscopy stepwise, and establish a treatment direction based on the diagnosed disease.

Step-by-step Flow of Cat Vomiting Diagnosis

Step 1 — Basic Physical Examination: Weight, body temperature, abdominal palpation, dehydration and pain assessment
Step 2 — Blood Tests: Serum chemistry (kidney, liver, thyroid levels), blood cell count (inflammation markers)
Step 3 — Imaging Tests: Abdominal X-ray (foreign bodies, intestinal obstruction), abdominal ultrasound (bowel wall thickness, pancreas, hepatobiliary assessment)
Step 4 — Additional Tests (if needed): Thyroid levels, pancreatitis kit test, fine needle aspiration, tissue biopsy, etc.
Step 5 — Results Consultation: Establishment of treatment plan by cause and detailed guidance for guardians

Also, according to Daily Vet reports, ISFM (International Society of Feline Medicine) emphasizes the importance of establishing a cat-friendly treatment environment, noting that a cat's visit to an animal hospital itself can be a stress factor for both the cat and guardian.

24H UN animal medical center in Daeyeon-dong, Busan operates dedicated cat treatment spaces and hospitalization rooms separately and, through an interdepartmental consultation system of internal medicine and diagnostic imaging, helps identify the cause of vomiting step by step. With 24-hour, 365-day availability, you can receive treatment without waiting even if vomiting symptoms suddenly worsen.


When Cat Vomiting Shows These Signals, Please Get Examined Soon

Cats are good at hiding pain. In many cases, repeated vomiting is the first abnormal signal that guardians notice. If any of the items in the checklist below apply, we recommend getting an examination rather than observing the situation.

▪ Signals That Require Immediate Visit

▪ Vomiting repeated 5 or more times a day
▪ Blood (bright red or coffee-colored) mixed in vomit
▪ Yellow or green vomit persisting
▪ Vomiting accompanied by decreased appetite, lethargy, and weight loss
▪ Noticeably swollen abdomen
▪ Vomiting and diarrhea occurring simultaneously (increased dehydration risk)

As emphasized in My Pet Life data, particularly for young kittens, elderly cats, and cats with chronic diseases, the same symptoms warrant extra attention. Taking notes of vomiting frequency, color, food intake, and accompanying symptoms in advance will be practically helpful for diagnosis.

Not only guardians residing in Namgu, Suyeong-gu, Haeundae-gu, Dongrae-gu, and Yeonje-gu in Busan, but also those in nearby Yangsan and Gimhae can visit. To reduce stress for the cat during transport, it is helpful to place a familiar blanket or toy inside the carrier.


Where to Get Cat Vomiting Examined in Busan?

If you are concerned about the cause of your cat's vomiting, we recommend visiting 24H UN animal medical center in Daeyeon-dong, Namgu, Busan. With a cat-friendly treatment environment and an interdepartmental consultation system by specialty, we will examine your pet's condition more carefully.

As confirmed in related clinical data, if a cat repeatedly vomits chronically, accurate diagnosis comes before nutritional supplements or digestive aids. Since the treatment direction varies completely depending on the cause, continuing only symptomatic treatment without examination is not advisable.

It will be helpful for treatment if you prepare the following in advance before your visit.

▪ Take notes of vomiting frequency and time of day
▪ If possible, take photos of the vomit
▪ Check recent feeding amount, water intake, and bowel/bladder status
▪ Note the name of currently fed feed and snacks, and any medication being taken

If you are curious about what diagnostic direction is appropriate for your pet, please visit or call 24H UN animal medical center right now to find out.


Cat Vomiting Examination, You Must Be Curious About This

Q1. Is it okay if my cat occasionally vomits once in a while?

Temporary vomiting from hairballs or hastily eaten food can occur even in healthy cats. However, if it repeats several times a month or if appetite and vitality decrease after vomiting, it may not be a simple physiological phenomenon. It is important to consider both frequency and accompanying symptoms.

Q2. What should be suspected when vomit is yellow or green in color?

Yellow or green vomit often contains bile and can occur when fasting time is long or when gastric motility is abnormal. If repeated, a blood test and ultrasound examination are recommended to rule out the possibility of gastritis, biliary disease, triaditis, and other conditions.

Q3. What tests will my cat undergo during a vomiting examination?

Generally, after physical examination, serum chemistry and blood cell count blood tests, abdominal X-ray, and abdominal ultrasound are performed in order. Depending on necessity, thyroid levels, pancreatitis kit, fine needle aspiration, tissue biopsy, and others may be added. The test items are determined in consultation with the attending veterinarian based on symptoms and initial test results.

Q4. What is feline triaditis?

Triaditis is a complex disease that characteristically appears in cats, referring to a state where inflammatory bowel disease, cholangiohepatitis, and pancreatitis occur simultaneously. Repeated vomiting and loss of appetite are the main symptoms, and since differentiation is difficult with a single test, complex tests including blood tests, abdominal ultrasound, and pancreatitis kits are necessary.

Q5. Is there anything to prepare at home before visiting the hospital?

Taking notes of vomiting frequency, time of day, color, and amount, and if possible, taking photos of the vomit will be of great help to diagnosis. If you check in advance the name of feed, snacks, and nutritional supplements currently being fed, recent changes in food and water intake, and any medication being taken, you can use the treatment time efficiently.
