Wondering, “Why is my cat throwing up and having diarrhea?” Experiencing a cat vomiting and diarrhea can concern pet owners, as these symptoms may indicate underlying issues affecting their feline friend’s health.

While it’s essential to remember that I am not a veterinarian, the information provided here offers insights into potential causes and recommendations for addressing these symptoms. Consulting with a professional veterinarian is imperative for accurate diagnosis and tailored treatment plans.

Gastrointestinal Upset:

Gastrointestinal upset in cats can be expected and may result from various factors. Abrupt changes in diet, introducing new foods, or consuming spoiled or inappropriate items can lead to irritation in the stomach and intestines.

In such cases, it is advisable to revert to a bland diet recommended by your veterinarian until the digestive system stabilizes. If symptoms persist or worsen, seeking professional veterinary advice is crucial.

My Cat Throwing Up and Having Diarrhea Because of Dietary Intolerance or Allergies:

Cats, like humans, can develop dietary intolerances or allergies over time. Certain ingredients in commercial cat food may trigger adverse reactions, leading to vomiting and diarrhea.

It is recommended to consult with your veterinarian to discuss potential allergens and explore specialized diets, such as hypoallergenic options, to address dietary sensitivities. Regularly transitioning to a new diet under veterinary guidance is essential to monitor your cat’s response.

Infections or Parasites:

Bacterial or viral infections and intestinal parasites like worms can significantly impact a cat’s gastrointestinal health. Common symptoms include vomiting and diarrhea; sometimes, blood may be present in the stool.

Diagnostic tests, such as fecal examinations, are essential to identify the specific infection or parasite, allowing the veterinarian to prescribe appropriate medications for treatment. 

My Cat Throwing Up and Having Diarrhea from Gastroenteritis:

Infections, exposure to toxins, or dietary indiscretions can trigger inflammation. Cats with gastroenteritis may experience frequent vomiting and diarrhea.

Treatment typically involves addressing the underlying cause, including medication to reduce inflammation, nutritional changes, and supportive care. Your veterinarian will examine to determine the most suitable course of action.


Pancreatitis, or pancreas inflammation, is another potential cause of cat digestive distress. Various factors, including dietary indiscretions or underlying health issues, can trigger this condition. Diagnostic tests, such as bloodwork and imaging, are necessary to confirm a pancreatitis diagnosis.

Treatment often involves hospitalization, fluid therapy, pain management, and a specialized diet. Early detection and intervention manage pancreatitis effectively.

Foreign Objects or Toxins:

Ingestion of foreign objects or toxic substances threatens a cat’s health and leads to gastrointestinal issues. If you suspect your cat has ingested something harmful, seek immediate veterinary attention.

Diagnostic tests are performed to identify the presence of foreign objects. Treatment may involve surgical removal or, in the case of toxins, supportive care and detoxification measures.

Stress or Anxiety:

Cats are sensitive creatures whose environment or routine changes can induce stress or anxiety. This emotional distress can manifest in physical symptoms, including vomiting and diarrhea.

Identifying and addressing potential stressors, such as changes in the household, new pets, or disruptions to their territory, is essential. Creating a calm and secure environment, offering hiding spots, and providing interactive toys can help alleviate stress. In severe cases, behavioral modification or medications may be recommended by your veterinarian.

Inflammatory Bowel Disease (IBD):

Inflammatory Bowel Disease (IBD) affects the gastrointestinal tract. Cats with IBD may exhibit symptoms like vomiting, diarrhea, weight loss, and changes in appetite. Diagnosing IBD requires a combination of clinical signs, blood tests, imaging, and, often, biopsy samples obtained through endoscopy. Management may involve:

  • Dietary modifications.
  • Medications to reduce inflammation.
  • Ongoing monitoring to ensure the cat’s well-being.

Organ Disorders:

Underlying organ disorders, such as liver or kidney diseases, can contribute to digestive issues in cats. These conditions may manifest with symptoms like vomiting, diarrhea, lethargy, and changes in urination.

Veterinary consultation and diagnostic tests are crucial to identifying and addressing these underlying organ issues. Early detection and appropriate management can significantly impact the cat’s quality of life.

Viral Infections:

Viral infections, such as feline coronavirus or feline leukemia, can affect the gastrointestinal tract and result in vomiting and diarrhea. Veterinary evaluation and testing are necessary for a proper diagnosis. Management may involve supportive care and addressing specific symptoms to enhance the cat’s comfort and well-being.

Why Is My Cat Throwing Up and Having Diarrhea: Promoting Long-Term Well-being

Ensuring your feline companion’s long-term health and well-being involves more than just addressing immediate symptoms. Consider incorporating a holistic approach to your cat’s care by focusing on preventive measures, a balanced diet, and regular veterinary check-ups.

Engage in interactive activities to stimulate physical and mental well-being, providing your cat a fulfilling and enriched environment. This proactive stance, combined with the expertise of your veterinarian, contributes to a resilient and contented cat, fostering a bond built on trust and attentive care.

Understanding why is my cat throwing up and having diarrhea is crucial in promoting their overall well-being. The range of possible issues, from gastrointestinal upset and dietary intolerances to infections, inflammations, and organ disorders, underscores the need for a thorough veterinary evaluation.
