Understanding Cat Vomiting and Diarrhea
When your cat is experiencing both vomiting and diarrhoea, it's a clear indication that their digestive system is distressed. This dual symptom set can range from a minor, transient upset to a sign of a serious underlying health issue. Identifying the cause is paramount for effective treatment and ensuring your feline companion recovers swiftly and safely.
As a pet owner, observing these symptoms can be worrying. This guide aims to provide clarity on what might be causing your cat to be sick and have diarrhoea, what signs warrant immediate veterinary attention, and what steps you can take at home to support your cat's well-being.
The most crucial initial step is observation. Note the frequency, consistency, and any other accompanying symptoms. This information will be invaluable when consulting with your veterinarian. While many cases resolve on their own with supportive care, some require urgent medical intervention.
It is vital to differentiate between occasional regurgitation and true vomiting. Vomiting usually involves abdominal heaving and retching, often preceded by nausea. Diarrhoea, on the other hand, is characterised by loose, watery stools, often with increased frequency or urgency.
When a cat is exhibiting both symptoms, it suggests a systemic upset affecting the entire gastrointestinal tract. This means the stomach and intestines are both inflamed or irritated, leading to the expulsion of contents and poorly formed waste.
- Dual symptoms indicate significant digestive upset.
- Observe frequency, consistency, and other signs.

- Differentiate vomiting from regurgitation and diarrhoea.
- Home care is supportive, but professional diagnosis is key.
Common Causes of Cat Vomiting and Diarrhea
The reasons behind a cat being sick and having diarrhoea are varied, spanning from dietary indiscretions to more serious medical conditions. Understanding these potential triggers can help you assess the situation and communicate effectively with your vet.
Dietary issues are frequent culprits. This includes sudden changes in food, eating spoiled food, or even consuming non-food items like string, plastic, or plants. Foraging outdoors can lead to ingestion of toxins or indigestible materials. Some cats develop food sensitivities or intolerances, which can manifest as vomiting and diarrhoea after eating specific ingredients. Even an excessive amount of cat poo from dietary fibre could be a factor.
Parasites are another significant cause, particularly in younger cats or those with weakened immune systems. Intestinal worms like roundworms, tapeworms, and protozoa such as Giardia and Coccidia can irritate the gut lining, leading to inflammation, vomiting, and diarrhoea. Feline hairballs, while often associated with vomiting, can also contribute to gastrointestinal upset and diarrhoea if they become lodged or cause significant irritation.
Medical Conditions and Infections
Beyond diet and parasites, a range of medical conditions can precipitate these symptoms. Infections, whether viral (like feline panleukopenia, though rare in vaccinated cats) or bacterial (such as Salmonella or E. coli), can cause severe gastrointestinal distress. Inflammatory Bowel Disease (IBD) is a chronic condition where the intestinal tract becomes inflamed, leading to recurring vomiting and diarrhoea. Pancreatitis, an inflammation of the pancreas, can also cause significant nausea, vomiting, and diarrhoea, often accompanied by a cat not eating.
Organ dysfunction, such as kidney disease or liver disease, can cause toxins to build up in the bloodstream, leading to nausea and vomiting. Hyperthyroidism, a common endocrine disorder in older cats, can accelerate metabolism and lead to weight loss, increased appetite, vomiting, and diarrhoea. In rare cases, gastrointestinal tumours or obstructions caused by foreign bodies can present with similar symptoms.
Toxins and poisons are a critical concern. Ingesting household plants, cleaning products, certain human medications, or antifreeze can cause acute and severe gastrointestinal signs, often including vomiting and diarrhoea. If you suspect your cat has ingested something toxic, contact your vet or an animal poison control centre immediately.
The presence of blood in cats poop or vomit is a serious sign that warrants immediate veterinary attention. It can indicate severe irritation, ulceration, or bleeding within the gastrointestinal tract.
Always consider recent changes in your cat's environment or routine, as stress can sometimes manifest in physical symptoms for sensitive felines.
Recognising the Signs: When to Seek Veterinary Help
While mild, isolated incidents of vomiting or diarrhoea might resolve with home care, a combination of both, or specific accompanying symptoms, signal that professional veterinary advice is essential. Prompt recognition of warning signs can prevent complications and ensure your cat receives timely treatment.
The frequency and severity of the symptoms are primary indicators. If your cat is vomiting multiple times within a few hours, or has persistent, watery diarrhoea that doesn't improve, a vet visit is necessary. Lethargy and lack of appetite are also significant red flags. A cat not eating for more than 24 hours, especially when also experiencing vomiting and diarrhoea, is a serious concern due to the risk of dehydration and other complications.
Critical Warning Signs
Look out for specific characteristics in the vomit or stool. Vomiting blood (haematemesis), or passing blood in the stool (haematochezia or melena – dark, tarry stools), indicates internal bleeding and requires immediate attention. If your cat appears to be in pain, is constantly trying to vomit without producing anything (a sign that can indicate bloat or obstruction), or shows signs of extreme distress, do not delay in seeking veterinary care.
Dehydration is a major risk with combined vomiting and diarrhoea. Signs include sunken eyes, dry gums, reduced skin elasticity (if you gently pinch the skin on their back, it doesn't snap back quickly), and decreased urination. Young kittens, elderly cats, and those with pre-existing health conditions are particularly vulnerable to rapid dehydration.
Other concerning symptoms include a distended abdomen, straining to defecate without producing stool, or a pale tongue and gums, which can indicate shock or severe anaemia. If your cat is exhibiting any of these critical warning signs, contact your veterinarian or an emergency animal hospital without delay. Your vet will likely ask about your cat's diet, behaviour, potential exposure to toxins or foreign objects, vaccination status, and any recent changes.
Accurate description of the vomit and cat poo is crucial for diagnosis.
Home Care and Supportive Measures
When symptoms are mild and your cat is otherwise alert and comfortable, you might be able to manage the situation at home with supportive care. However, it is always best to err on the side of caution and consult your veterinarian, especially if you are unsure about the severity of the symptoms or your cat's underlying health.
The first step in home care is often to withhold food for a short period, typically 12-24 hours, to allow the gastrointestinal tract to rest. This is generally only advisable for adult cats; kittens, elderly cats, or those with specific health conditions should not be fasted without veterinary instruction. Ensure fresh water is always available. If your cat is reluctant to drink, you can offer small amounts of water frequently or try a bland, low-sodium chicken or fish broth (ensure it contains no onion or garlic).
After the fasting period, reintroduce food gradually with a bland, easily digestible diet. Common recommendations include boiled, unseasoned chicken or turkey breast (no skin or bones) mixed with plain boiled white rice, or a specialised veterinary diet formulated for gastrointestinal upset. Feed small, frequent meals rather than one or two large ones. This diet should be continued for several days, gradually transitioning back to your cat's normal food over a week or more, provided symptoms have fully resolved.
It is important to monitor your cat closely during this recovery period. Keep an eye on their appetite, hydration levels, stool consistency, and overall demeanour. If symptoms worsen, return, or new concerning signs appear, seek veterinary advice immediately.
The goal of home care is to support your cat's recovery while avoiding further irritation to their sensitive digestive system.
Avoid giving your cat any over-the-counter human medications for diarrhoea or vomiting unless specifically instructed by your veterinarian. Many human medications are toxic to cats, and even seemingly safe ones can mask symptoms or interfere with veterinary treatment.
If your cat is vomiting white foam, try offering a small amount of water or a bland diet. If it persists, consult your vet, as it can sometimes indicate an underlying issue.
Veterinary Diagnosis and Treatment Options
When you bring your cat to the vet for vomiting and diarrhoea, they will begin with a thorough physical examination and a detailed history. Based on these findings, various diagnostic tests may be recommended to pinpoint the exact cause. This diagnostic process is crucial for effective treatment planning.
Common diagnostic steps include blood tests to check for infection, inflammation, organ function (kidneys, liver), and electrolyte imbalances, which are critical when dealing with dehydration. A faecal examination is performed to identify intestinal parasites like worms or protozoa. Urinalysis can help assess kidney function and hydration status.
Advanced Diagnostics
If initial tests are inconclusive, or if a more serious condition is suspected, your vet may suggest imaging. X-rays can reveal foreign bodies, obstructions, or abnormalities in the size or shape of abdominal organs. An ultrasound offers a more detailed view of the gastrointestinal tract, pancreas, and other abdominal organs, helping to detect inflammation, tumours, or thickenings of the intestinal walls indicative of IBD.
In some cases, a biopsy of the intestinal lining may be necessary to definitively diagnose conditions like IBD or cancer. This can be obtained via endoscopy (a less invasive procedure using a flexible camera) or surgery. If a blockage is suspected, diagnostic imaging is key to determining its location and nature, differentiating between an object and a functional obstruction.
Treatment will depend entirely on the diagnosis. For parasitic infections, antiparasitic medications will be prescribed. Bacterial infections may require antibiotics. If a foreign body is causing an obstruction, surgery is often the only viable treatment. For IBD or pancreatitis, treatment typically involves dietary management, anti-inflammatory medications, and sometimes immunosuppressants.
Fluid therapy (intravenous or subcutaneous) is a common supportive treatment to combat dehydration and correct electrolyte imbalances. Anti-emetic medications may be given to control vomiting, and anti-diarrhoeal agents might be used cautiously, depending on the underlying cause. For chronic conditions like IBD, long-term management strategies are developed, focusing on diet, medication, and regular veterinary check-ups.
Never administer prescription medications without veterinary guidance, as incorrect dosages or inappropriate drugs can be harmful.
Prevention Strategies for Digestive Upset
While not all instances of cat vomiting and diarrhoea can be prevented, implementing certain strategies can significantly reduce the likelihood of your feline companion experiencing digestive distress. Proactive care focuses on diet, environment, and regular health checks.
Ensure your cat has a balanced, high-quality diet appropriate for their age and health status. Avoid sudden changes to their food; if a change is necessary, transition gradually over 7-10 days by mixing increasing amounts of the new food with the old. Store cat food properly to prevent spoilage and keep it away from pests. Be mindful of what your cat might ingest from around the house or garden. Keep toxic plants, chemicals, and small objects that could be swallowed out of reach. Secure rubbish bins to prevent access to spoiled food or non-food items.
Regular Veterinary Care and Parasite Control
Regular veterinary check-ups are fundamental. Annual or semi-annual exams allow your vet to detect potential health issues early, before they become severe. This includes discussing any subtle changes in your cat's behaviour or habits that you might have noticed. A robust parasite control programme is also vital. Administering regular deworming treatments as recommended by your vet helps prevent internal parasites that can cause vomiting and diarrhoea. Flea control is also important, as fleas can transmit tapeworms.
For cats prone to hairballs, regular grooming can help reduce the amount of fur they ingest. Brushing your cat several times a week, especially long-haired breeds, can make a significant difference. Specialised hairball remedies or diets can also be beneficial. If your cat has a history of eating non-food items or shows obsessive behaviour, working with your vet to address the underlying cause, which could be stress or a nutritional deficiency, is important.
Educating yourself on common cat toxins and keeping them out of your home is a primary preventative measure.
If your cat is prone to vomiting, consider switching to a specialised diet designed to aid digestion or reduce hairballs, after consulting your vet.
