Cat Vomits White Mucus or Foam

Cat vomiting white mucus or foam may contain a large amount of gastric juice and can be caused by various reasons. It is not recommended for owners to treat this symptom themselves by giving the cat anti-vomiting medication. It is advised to take the cat to a pet hospital, where the doctor will conduct a comprehensive examination, diagnose the cause, and give targeted medication.

Indigestion

A cat's stomach is similar to that of humans, and it digests food through gastric juice. The pH level is lower than in humans, and the stomach acid is more acidic. If a cat stops eating due to environmental changes or food switches and experiences indigestion, it can lead to a lack of food in the stomach, causing continuous stimulation of the gastric acid, which results in vomiting. The vomit may contain a large amount of foam or mucus. In this case, the owner should feed the cat smaller meals and provide adequate water to rinse the esophagus and reduce the damage to the mucous membrane caused by the gastric juice.

Hairball Syndrome

When a cat licks too much hair into its gastrointestinal tract, the hair accumulates into ball-like clumps, stimulating the gastrointestinal response and causing frequent dry heaving and vomiting. Since the hairball is blocked in the stomach, the vomit mainly contains white mucus or foam. In this case, the owner can help the cat pass the hair by feeding it catnip or hairball gel. Additionally, giving the cat probiotics is appropriate.

Ingestion of Toxic Substances

If a cat eats toxic substances (such as lilies, chocolate, human medication, grapes, etc.), it may stimulate the gastrointestinal tract and cause vomiting. If the cat has access to these items, it is necessary to be vigilant and seek medical attention immediately.

Gastroenteritis

Gastroenteritis is a common cause of vomiting in cats and is often accompanied by diarrhea and bloody stools. Since gastroenteritis can lead to dehydration and collapse, it can be life-threatening. It is advised to seek immediate medical attention. At the pet hospital, the doctor will usually perform fecal and inflammatory marker tests. If necessary, an abdominal ultrasound and X-ray will be done. After a professional diagnosis, the doctor will provide a reasonable treatment plan. If the cat is severely dehydrated, it will be given intravenous fluid therapy, and symptomatic treatment for vomiting and diarrhea will be administered.
