Kittens vomiting blood may be infected with feline distemper virus, especially kittens aged 3-5 months that have not been vaccinated. It may also be caused by ingestion of foreign bodies, hairball disease, gastroenteritis and other reasons. Regardless of the reason why the kitten vomits blood, the owner should take the kitten to the pet hospital for examination and treatment in time. If not treated in time, it may cause anemia, dehydration, etc., and even endanger the kitten's life.

1. Infection with feline plague virus

If the kitten is young and has not been vaccinated, it is necessary to consider whether it is vomiting caused by infection with feline distemper virus, especially for kittens aged 3-5 months. If vomiting occurs frequently, damage to the esophagus or gastric mucosa will lead to bleeding. Symptoms such as depression, decreased appetite, abnormal body temperature, lethargy, vomiting, diarrhea, and dehydration may also occur. The owner can do a cat distemper virus antigen test on the kitten. After the diagnosis is confirmed, it needs infusion and injection treatment, and at the same time, the surrounding environment must be completely disinfected.

When raising kittens in daily life, owners need to inject kittens with the vaccine against feline plague according to the vaccination procedures, so that the body can produce protective antibodies to resist the invasion of the virus.

2. Swallowing foreign objects

If a kitten swallows chicken bones, fish bones, needles and other foreign objects and scratches the stomach or intestines, it will cause vomiting of blood. The owner can recall whether the cat has eaten solid food, and promptly take the kitten to the pet hospital for a x-ray examination to confirm the location of the foreign body and the damage to the digestive tract, and then remove the foreign body. If necessary, surgical treatment is required.

When raising cats, do not feed them sharp objects such as chicken bones, fish bones, duck bones, etc. to avoid scratching or blocking the digestive tract.

　3. Hairball syndrome

When a cat licks its hair, it swallows a lot of hair and forms hair balls in the stomach, which affects the gastrointestinal tract and causes gastritis or blockage, which may cause the cat to vomit blood or hair balls. It is recommended to feed cats hair loss cream or cat grass to help the hair balls be discharged smoothly. In this regard, the owner can check whether the cat has vomited hair balls. If so, it is recommended to wait until the cat stops vomiting and feed it hair removal cream or cat grass to help the hair balls be discharged smoothly.

4. Gastroenteritis

Due to gastroenteritis caused by improper diet, cold, parasites, viruses, etc., vomiting of blood and water may also occur in severe cases, along with symptoms of listlessness and loss of appetite. The owner can first feed the cat an appropriate amount of probiotics to adjust the balance of gastrointestinal flora, and then take the cat to the pet hospital for examination to confirm the specific cause and then take corresponding treatment measures.
