Why Is My Cat Throwing Up After Pooping?

If your cat is constantly throwing up after pooping, it could be a cause for concern, and several potential reasons may be contributing to this behavior. It’s important to note that vomiting in cats can be a sign of various underlying issues, and a thorough veterinary examination is recommended to determine the specific cause. Here are some possible reasons why a cat may throw up after pooping:

– Gastrointestinal Issues: Your cat may be experiencing gastrointestinal problems, such as inflammatory bowel disease (IBD), infections, parasites, or other digestive disorders. These conditions can lead to vomiting as a symptom.

– Dietary Factors: Sudden changes in diet, food allergies, intolerances, or ingestion of something indigestible can cause digestive upset, leading to vomiting.

– Hairballs: Cats groom themselves by licking, and hair ingested during grooming can form hairballs in the stomach. If the hairball is not adequately passed through the digestive system, it may lead to vomiting.

– Constipation or Megacolon: Difficulty in passing stool due to constipation or a condition like megacolon (enlarged colon) can cause discomfort and lead to vomiting.

– Obstruction: An obstruction in the gastrointestinal tract, such as a foreign object or a mass, can lead to vomiting. This is a serious condition that requires immediate veterinary attention.

– Infections or Parasites: Gastrointestinal infections or the presence of parasites, such as worms, can lead to digestive disturbances and vomiting.

– Dental Issues: Pain or discomfort in the mouth, throat, or digestive tract, possibly due to dental problems, may result in vomiting after eating or defecating.

– Systemic Diseases: Certain systemic diseases, such as kidney disease or diabetes, can manifest with gastrointestinal symptoms, including vomiting.

– Stress or Anxiety: Cats can exhibit physical symptoms in response to stress or anxiety. Changes in the environment, new pets, or other stressors may contribute to vomiting.

Should I Be Concerned If My Cat Only Occasionally Throws Up After Pooping?

While occasional vomiting in cats is not unheard of, it should not be ignored as it may be a symptom of underlying health issues. Some cats may vomit due to eating too quickly, having a sensitive stomach, or due to hairballs. However, if the vomiting is accompanied by other symptoms such as weight loss, lethargy, diarrhea, or changes in appetite, it is advisable to consult with a veterinarian. Changes in poop or the process of pooping can put pressure on the cat’s abdomen leading to vomiting. But again, if this is a regular occurrence, it is necessary to seek advice from a professional to rule out conditions such as gastrointestinal problems or parasites. Regular health check-ups can help ensure your cat’s wellbeing and catch potential health issues early on.

What Should I Do If My Cat Is Vomiting After Defecating?

If your cat is vomiting after defecating, it’s essential to take the following steps:

Seek Veterinary Help: If your cat frequently vomits after defecating, it’s critical to consult with a vet as soon as possible. This could be a sign of serious health issues such as gastrointestinal problems or parasites.

Monitor and Document Symptoms: Keep a close eye on your cat’s behavior and symptoms. Document instances of vomiting, their bowel movements, and any other unusual behaviors. This information will be useful when consulting with your vet.

Hydration: Ensure there’s always fresh water to rehydrate your cat. Vomiting can dehydrate your cat quickly, which can lead to further health complications.

Avoid Food Immediately After Vomiting: Allow your cat’s stomach to settle for a little while after a vomiting episode before offering food again.

Consider Dietary Changes: Under your vet’s guidance, you may need to modify your cat’s diet. This could involve changing to a different type of cat food, or introducing a special diet to help manage your cat’s health condition.

Medication: Your vet may prescribe medication to help manage your cat’s condition and reduce instances of vomiting. Always follow your vet’s instructions when administering medication.

Regular Follow-ups: Regular follow-ups with the vet are important to monitor your cat’s condition and make necessary adjustments to their treatment plan. 

Be patient and provide a comfortable environment for your cat during the recovery period. It’s vital to be observant and follow the advice of your veterinarian.

How Can I Prevent My Cat From Throwing Up After Pooping?

Preventing your cat from throwing up after pooping depends on identifying and addressing the underlying cause of the behavior. Here are some general tips that may help reduce the likelihood of your cat experiencing this issue:

  • Monitor Diet: A balanced diet is essential in maintaining your cat’s digestive health. Avoid sudden changes in their diet as it may lead to upset stomachs and vomiting.
  • Slow Feeding: If your cat tends to eat quickly, consider using a slow feeder bowl to slow down their eating pace, which can help prevent vomiting.
  • Hydration: Ensure your cat is properly hydrated. Dehydration can lead to constipation which may cause straining during defecation and subsequent vomiting.
  • Regular Exercise: Regular physical activity can aid in efficient digestion and help prevent constipation.
  • Hairball Control: Regular grooming your cat and using hairball control products can help minimize hairball formation, which may lead to vomiting post-defecation.
  • Portion Control: Overfeeding can cause digestive issues in cats. Make sure to follow recommended feeding guidelines to prevent overconsumption.
  • Regular Vet Check-ups: Regular vet visits can help detect any underlying health issues that may be causing your cat to vomit after pooping. 


In conclusion, it is not uncommon for cats to throw up after pooping, but it should not be ignored. It could be a sign of a serious underlying issue that needs to be addressed by a veterinarian. By understanding the potential causes and taking preventive measures, such as proper diet and regular check-ups, we can ensure the health and well-being of our feline companions. So if you notice your cat throwing up after pooping, don’t brush it off as a normal occurrence, but instead take proactive steps to address it. As pet owners, it is our responsibility to provide the best possible care for our furry friends. Let’s stay vigilant and attentive to any changes in our cats’ behavior and seek professional help if needed. Remember, early detection and intervention are key in keeping our cats healthy and happy.
