Sudden Onset of Vomiting in Cats
Cats will commonly vomit from time to time, often because they might have eaten something that upset their stomachs, or simply because they have sensitive digestive systems. However, the condition becomes acute when the vomiting does not stop and when there is nothing left in the cat's stomach to throw up except bile. It is important you take your pet to a veterinarian in these cases.
While vomiting may have a simple, straightforward cause, it may be an indicator of something far more serious. It is also problematic because it can have a wide range of causes, and determining the correct one may be complicated.
Symptoms of Sudden and Severe Vomiting
Some of the more common symptoms include:
- Non-stop vomiting
- Pain and distress
- Bright blood in the stool or vomit (hematemesis)
- Evidence of dark blood in the vomit or stool (melena)
Causes of Sudden and Severe Vomiting
Some possible risk factors include:
- Heat stroke
- Liver disease
- Changes in the diet
- Dietary indiscretion
- Gobbling food/eating too fast
- Allergic reaction to a particular food
- Food intolerance (beware of feeding an animal "people" food)
- Adrenal gland disease
- Dislocation of the stomach
- Intestinal parasites (worms)
- Obstruction in the esophagus
- Metabolic disorders such as kidney disease
Diagnosis of Sudden and Severe Vomiting
If possible take a sample of your cat's vomit to the veterinarian. The veterinarian will then take the cat's temperature and examine its abdomen. If it turns out to be no more than a passing incident, the veterinarian may ask you to limit the cat's diet to clear fluids and to collect stool samples over that period, as the underlying cause may be passed along in the stool. Occasionally, the cat's body may use vomiting to clear the intestines of toxins. If the vomit contains excessive amounts of mucus, an inflamed intestine may be the cause. Undigested food in the vomit can be due to food poisoning, anxiety, or simply overeating. Bile, on the other hand, indicates an inflammatory bowel disease or pancreatitis.
If bright red blood is found in the vomit, the stomach could be ulcerated. However, if the blood is brown and looks like coffee grounds, the problem may be in the intestine. Strong digestive odors, meanwhile, are usually observed when there is an intestinal obstruction. If the obstruction is suspected in the cat's esophagus, the veterinarian will conduct an oral exam. Enlarged tonsils are a good indicator of such an obstruction.
Treatment for Sudden and Severe Vomiting
Treatment is dependent on the underlying cause of the vomiting; some of the veterinarian's possible suggestions include:
- Dietary changes
- Medication to control the vomiting (e.g., cimetidine, anti-emetic)
- Antibiotics, in the case of bacterial ulcers
- Corticosteroids to treat inflammatory bowel disease
- Surgery, in the case of tumor-caused vomiting
- Special medications for treating chemotherapy induced vomiting
Always follow the recommended treatment plan from your veterinarian. Do not experiment with medications or food. Pay close attention to your cat and if it does not improve, return to your veterinarian for a follow-up evaluation.
