Discovering blood in your cat’s vomit, a condition known as hematemesis, is alarming and demands urgent veterinary care.

In this comprehensive guide by Beaconpet, delve into the causes, symptoms, diagnosis, and vital treatment options for cats experiencing hematemesis.

Vomiting Blood in Cats: Causes, Symptoms, and Treatment

Causes

Gastrointestinal ulcers

Gastrointestinal ulcers can occur in cats due to various factors such as stress, certain medications, bacterial or viral infections, or underlying health conditions. These ulcers can erode the lining of the digestive tract, leading to bleeding and subsequent vomiting of blood.

Rat poison ingestion

If a cat ingests rat poison, it can lead to a clotting disorder known as anticoagulant rodenticide toxicity. This can cause spontaneous bleeding, including bleeding in the gastrointestinal tract, resulting in the vomiting of blood.

Clotting disorders

Certain clotting disorders can lead to spontaneous bleeding in cats. These disorders can be genetic or acquired and can cause blood vessels in the digestive tract to rupture, leading to the presence of blood in vomit.

Inflammatory bowel disease

Inflammatory bowel disease (IBD) is a chronic condition that affects the digestive tract of cats. It is characterized by inflammation, ulceration, and thickening of the intestinal walls. In severe cases, this inflammation can result in bleeding and subsequent vomiting of blood.

Heartworm disease

Heartworm disease is caused by a parasitic infection transmitted through mosquito bites. It primarily affects the heart and lungs of cats. In severe cases, heartworm disease can lead to bleeding, including bleeding in the digestive tract, resulting in the presence of blood in vomit.

Foreign material in the digestive tract

If a cat ingests foreign objects such as string, hairballs, or bones, it can cause damage to the digestive tract. This damage can result in bleeding and the subsequent vomiting of blood.

Symptoms

The primary symptom of vomiting blood in cats is the presence of blood in vomit. The blood may appear as bright red streaks if it originates from the upper part of the digestive tract. If the blood originates from the lower part of the digestive tract, it may have a coffee ground appearance. Other accompanying symptoms may vary depending on the underlying cause and may include loss of appetite, weight loss, lethargy, diarrhea, or abdominal pain.

Diagnosis

If you suspect that your cat is vomiting blood, it is crucial to seek veterinary attention immediately. The veterinarian will perform a thorough examination to determine the underlying cause of the vomiting. The following diagnostic tests may be conducted:

Physical examination

The veterinarian will examine your cat for any visible signs of illness, such as pale gums or abdominal pain.

Blood tests

Blood tests may be conducted to evaluate the cat’s overall health and check for any abnormalities, including clotting disorders or signs of infection.

X-rays

X-rays may be taken to assess the condition of the digestive tract and check for any foreign objects that may be causing internal damage.

Ultrasound

An ultrasound may be performed to evaluate the structure and function of the organs in the abdomen and identify any abnormalities.

Endoscopy

Endoscopy involves the insertion of a thin, flexible tube with a camera into the digestive tract to visually inspect the lining of the esophagus, stomach, and intestines. This procedure can help identify ulcers, tumors, or other abnormalities.

Biopsy

If necessary, the veterinarian may perform a biopsy to obtain a small sample of tissue from the digestive tract for further evaluation.

Treatment

The treatment for vomiting blood in cats will depend on the underlying cause identified through diagnosis. The primary goal of treatment is to address the cause of the bleeding and provide supportive care. The following treatment options may be considered:

IV fluids

In cases of severe bleeding, cats may require intravenous fluids to stabilize their condition and maintain hydration.

Blood transfusion

If the cat has experienced significant blood loss, a blood transfusion may be necessary to replace the lost blood and restore normal blood cell levels.

Endoscopy

In some cases, endoscopy may be used as a treatment option. During the procedure, the veterinarian can cauterize bleeding ulcers or remove foreign objects causing damage.

Surgery

Surgical intervention may be required to remove foreign objects or to address underlying conditions such as gastrointestinal ulcers or tumors.

Supportive care

Supportive care may be provided to manage symptoms and promote healing. This may involve medication to control inflammation, pain relief, and a specialized diet to support gastrointestinal health.

Treatment for gastrointestinal ulcers

Symptoms of inflammatory bowel disease

Symptoms of inflammatory bowel disease may include chronic diarrhea, vomiting, weight loss, loss of appetite, and abdominal pain.

Heartworm disease is caused by a parasitic infection transmitted through mosquito bites. Cats can become infected if bitten by an infected mosquito carrying heartworm larvae.

Symptoms of heartworm disease

In cats, symptoms of heartworm disease can vary and may include coughing, difficulty breathing, weight loss, lethargy, vomiting, or sudden collapse.

Treatment for heartworm disease

There is no specific treatment for heartworm disease in cats, and management focuses on supportive care to alleviate symptoms. Preventive measures, such as using monthly heartworm preventives, are essential to protect cats from this potentially fatal disease.

Prevention of heartworm disease

Prevention of heartworm disease in cats involves using monthly heartworm preventives. These preventives are available as topical or oral medications and are highly effective in preventing infection if used consistently.
