What is Vomiting of Blood?

Hematemesis is often a sign of gastrointestinal disorders or bleeding. Contact your vet immediately during the first instance if possible, but especially if the vomiting of blood has persisted for more than 3 days.

While vomiting in cats can be quite common, vomiting of blood, known as hematemesis, may be an indication of a serious condition in cats that warrants immediate veterinary attention. The blood in a cat’s vomit may be bright red or dark-colored with an appearance often likened to “coffee grounds”, which can be differentiated from spots of blood present in the vomit. Spots of blood in the vomit may result from irritation caused by vomiting. However, it is a good idea to seek veterinary attention despite what the blood looks like or what you think the cause may be.

Symptoms of Vomiting of Blood in Cats

If blood in your cat’s vomit is bright red, it is fresh and may have been caused by external trauma to the esophagus, such as swallowing a foreign object, or an oral condition. Darker blood may indicate issues lower in the digestive tract. If the problem persists, seek immediate veterinary attention for your cat as soon as you notice any of the following symptoms:

There are several causes of vomiting of blood in cats. Your vet will be able to determine the cause upon diagnosis. Possible causes include, but are not limited to:

  • Ulcers located in the gastrointestinal tract or esophagus
  • Respiratory disease
  • Certain cancers, particularly if tumors are bleeding

Diagnosis of Vomiting of Blood in Cats

Your vet will ask you about any specific events or known disorders that may have led to the vomiting. Be sure to answer all your vet’s questions to the best of your ability, and be prepared to provide a list of any medications your cat is currently taking.

Your vet can use a number of tests to determine the cause of vomiting of blood. The vet may make a tentative diagnosis based on presentation of symptoms. Tests are required for a definitive diagnosis. Your vet may analyze your cat’s blood and urine in addition to performing an endoscopy, c, ultrasound, and x-rays. If cancer is suspected, the vet may take a biopsy of the gastrointestinal tract.

Do not take a sample of vomit or stool to the vet with you unless it is specifically requested, since you may not have a sanitary means of transport. Vets cannot effectively test vomit samples for disease and other conditions, so these may not be helpful.

Treatment of Vomiting of Blood in Cats

Treatment will vary based on the underlying cause:

Disease

In many cases of vomiting of blood caused by disease, treatment may be more aggressive depending on the disease. Certain diseases may be managed by drug therapy. Gingivitis can be treated through a thorough dental cleaning. Hospitalization and intravenous fluid therapy may also be required to restore electrolytes and fluids lost during vomiting.

Ulcers

The vet may prescribe medication that will help prevent the ulcer from causing any more harm to the lining of the stomach and reduce the acidity of the stomach environment. A special or bland diet is usually also prescribed. Surgery is another method of treatment for ulcers, which will require an endoscopy beforehand to locate the ulcers. Your vet will schedule a follow-up appointment to monitor the ulcers through endoscopy.

Cancer

Depending on the location and stage of the cancer, treatment methods may include surgery, chemotherapy, or radiation treatment. Your vet will discuss your options with you based on your cat’s specific needs.

Recovery of Vomiting of Blood in Cats

Recovery and prognosis will vary based on the underlying cause and the recommended course of treatment. Be sure to follow all your vet’s treatment and recovery instructions carefully.

If your cat has been diagnosed with gingivitis, you will need to ensure that you take proper care of your cat’s teeth by brushing them each day. Your vet will be able to advise you on a dental care regimen.

If your cat has been prescribed drug therapy to treat gastrointestinal ulcers, it is imperative that you administer the medication for the entire duration of the recommended treatment period even if symptoms start to clear up. Failure to do so could result in aggressive recurrence.

If your cat has had surgery, ensure that he or she does not irritate the surgery site. After any major operation or procedure, you’ll need to provide a warm, safe place for your cat to rest. Additionally, you should ensure that clean drinking water is always available and accessible. Your vet will be able to advise you on dietary changes.

Vomiting Blood

Two of my cats are vomiting blood that is bright red. Neither one has been outside or exposed to plants or poison. I did give them canned meat last night and they don't usually have it. The only emergency vet near by is an hour and a half away. Is there anything I can do or watch for to help them or should I go to the vet?

Hello, vomiting blood is very concerning and the best thing that your cats see a vet. This meat could have been bad and upset their stomachs. Usually, when a pet is vomiting, I recommend a bland diet. But vomiting blood could be an indication of a GI ulcer or something more serious wrong that would need immediate vet attention.

Hello I’m sorry that your cat is not feeling well. I recommend that you take her to a veterinarian for an exam. She could be really constipated and if she continues to vomit she could become dehydrated. They may want to run labwork or perform xrays to see what is going on internally. Good luck.

Thank you for your question. Vomiting blood is a problem, I see why you are concerned. If he/she is still having this problem, it would be best to have your veterinarian look at your pup to make sure that all is okay, and see if any treatment is needed. I hope your puppy is okay!

Thank you for your question. . Possible causes for what you are describing might be parasites, or intestinal infections or blockages. Since I cannot see her, It would be best to have your pet seen by a veterinarian, as they can examine them, see what might be going on, and get treatment if needed.

Vomiting Blood

My cat vomited white foam around 3 times, followed by blood. She also had soft poop for around one week. I went to vet 2 weeks ago and they gave her a shot, some pills to stop vomit and vitamin C. My doc suspected that she had flea fever or food poisoning. After the visit she is back to normal but after 2 weeks she vomit blood again with slight diarrhoea. However, she can eat and play well.

Pink Vomit

My cat goes out to the garden and eat some kind of plant I think it's lemon grass. Whenever he does, he vomits. However,this time he vomitted two times and the second time there was a bit of pinkish liquid. He was vomitting a week earlier due to worms, but took the treatment immediately and got better. I am not sure how severe this is and it is very late no Vet is available. I would really apreciate some help. Thank you!

Dark Bright Slimy Blood

I have 3 cats. My tortoiseshell is my original cat. I have a 8 year old male cat who is big, but stomach has always looked saggy and indented since we took him in a few months ago. I have a younge male that showed up at my door this past Christmas. I found a large amount of blood. Its always outside a litter box so I'm not sure if its vomit or feces. I'm assuming its vomit. It looks like the color of ketchup and bbq sauce mixed, and slimy. Nothing else in it. Just straight up blood. I'm guessing it is the 8 year old male. Considering I had no intention of keeping the two males more than a couple days until finding homes I did not take them to the vet. At this point I can not take them to the vet. Absolutely no money to do so. No programs are available to help.

Yesterday, I came home to find my mancoon mix cat having trouble breathing, or panting heavily. I took him in my room to research on line his symptoms. Within just five minutes my cat started vomiting blood an howling turning upside down and clawing at his neck like something was keeping him from getting air. I checked his throat, even tried hymlic removal to find nothing blocking his airway. The blood started gushing out of his mouth and he died. I am so distraught I need to know what happend. I have four other cats and they are my children since I bore none. He was a purfectlly happy cat that morning showing no symptoms of what came next.
