How To Treat Gastroenteritis In Cats

If your cat shows signs of gastroenteritis, take him to the vet immediately. Your doctor will ask you for your cat’s medical history and perform a detailed physical exam.

At this point, your cat’s medical history is of great importance for an accurate and rapid diagnosis. So, what information should you pay attention to for a detailed medical history? Let’s examine it in detail:

  1. Does your cat have a long-term disease?
  2. What did he consume in food and drink over the last two days?
  3. How often does the current diet plan feed? How much does it eat?
  4. Have you given your pet any medication, vitamins, or supplements in the past month?
  5. Has it had any illness recently?
  6. Have you made any food changes? Does it eat treats?
  7. Have you been exposed to substances such as medicines, cleaning products, or pesticides in the home recently?
  8. Has it had contact with a new animal or person in the past?
  9. Have your cat experienced previous episodes of diarrhea and vomiting? What was the cause and what treatments have been applied?

After taking a detailed medical history, it is time to conduct tests to confirm the diagnosis. However, the specific tests that the veterinarian will perform will vary based on the severity of the case, its duration, and the cat’s medical history and physical exam.

Your veterinary may recommend a complete blood count (Hemogram) to detect any dehydration, anemia, toxins exposure or infection in the cat.

A stool analysis can identify parasitic, bacterial, or fungal infections of the intestine.

An abdominal x-ray will determine whether there are any abnormalities or obstructions in the stomach or intestines. This technique is very successful at controlling causes or foreign bodies that can lead to gastroenteritis. Contrasting x-ray may be requested in case of any suspected foreign body.

An abdominal ultrasound detects any obstruction in the intestine and the presence of abnormal conditions such as cancer.

Urinalysis in urinary tract infection and kidney disease as well as diabetes determines the presence of disease or dehydration.

Treatment for gastroenteritis is planned based on the underlying cause of the disease.

If your cat has symptoms of diarrhea and vomiting, these symptoms will be immediately controlled by antibiotics, antiemetics (anti-nausea medications), fluid supplements, and antidiarrheals.

After specific therapy, a treatment plan will be applied according to the underlying cause of the condition.

There are many other treatment options, including surgery, dietary changes, antibiotics, anti-inflammatory or anti-parasitic drugs and some substances that protect the gastrointestinal tract can be used to prevent stomach ulcers.

You should not give your cat any medication that your vet has not prescribed.

How To Prevent Gastroenteritis In Cats?

The most common causes of gastritis include eating a new food, exposure to toxins, and ingesting foreign objects. For this reason, you should keep harmful things your cat shouldn’t eat in a place it can’t reach.

If you’re going to switch to a new diet, make sure to mix in the new food slowly with the old food. Start by increasing the amount of old food, then increase the amount of new food.

Regular veterinary checkups, fecal scans and blood tests may detect a possible disease that can cause gastroenteritis. Additionally, to reduce your cat’s risk of gastroenteritis, you should make regular internal and external parasite protection practices, cleaning practices and prevent contact with foreign pets.
