Megacolon in Cats

Symptoms, Causes & Natural Remedies

Megacolon in cats is a serious condition where the large intestine (colon) becomes abnormally enlarged and loses its ability to function properly. This can lead to a variety of uncomfortable and potentially life-threatening symptoms, as well as digestive complications that can require veterinary treatment. In this guide, we will explore the symptoms, causes, and natural treatments of megacolon in cats.


The symptoms of megacolon in cats can vary depending on the severity and duration of the condition, but some common signs to watch out for include:

  • Constipation and difficulty passing stool
  • Abdominal discomfort, bloating, and pain
  • Vomiting and loss of appetite
  • Straining to defecate or vocalizing while attempting to pass stool
  • Foul-smelling breath and stool
  • Dehydration and weight loss
  • Lethargy and depression

If you notice any of these symptoms in your cat, it’s important to have your kitty checked by a veterinarian for an accurate diagnosis. 


There are several factors that can contribute to the development of megacolon in cats, including:

  • Chronic constipation and dehydration, which can cause the colon to become overstretched and unable to contract normally.
  • Nerve damage or dysfunction, which can disrupt the colon’s ability to move stool through the digestive system.
  • Obesity, which can put additional pressure on the colon and interfere with its function.
  • Inflammatory bowel disease (IBD) or other gastrointestinal disorders, which can lead to chronic inflammation and damage to the colon.
  • While some cats may be more prone to developing megacolon due to genetic factors, it’s important to note that this condition can affect cats of any breed or age.

Natural Treatments:

If your cat has been diagnosed with megacolon, your veterinarian will likely recommend a combination of medical and dietary interventions to help manage their symptoms. However, there are also several natural treatments that can be used in conjunction with veterinary care to support your cat’s overall health and well-being.

  1. Probiotics: Probiotics are beneficial bacteria that can help improve digestive function and reduce inflammation in the gut. Adding a high-quality probiotic supplement to your cat’s diet may help improve their stool quality and promote a healthier gut microbiome.
  2. Fiber-rich foods: Increasing your cat’s fiber intake can help regulate their bowel movements and prevent constipation. You can add fiber to your cat’s diet by feeding them pure canned pumpkin.
  3. Herbal remedies: Some herbs, such as slippery elm and marshmallow root, have anti-inflammatory and soothing properties that can help reduce inflammation in the colon and improve digestive function. 
  4. Exercise: Regular exercise can help improve your cat’s overall health and support healthy digestive function. Encourage your cats to play and engage in physical activity with them on a daily basis to help keep their colon functioning properly.

Dr. Chris Bessent’s Megacolon Recommendation:


Probiotics are beneficial bacteria that help balance the gut microbiome to support gut health. 

Prebiotics feed probiotics. They’re long-chained sugars that encourage the growth of beneficial bacteria in the gut. 

Digestive Enzymes break down large molecules into smaller, more usable pieces. (Basically, they help your cat digest and use his food!)

Gut-Soothing Herbs soothe tummy troubles naturally, without interfering with the digestive enzymes & probiotics already at work. 

Use Microflora for…

  • The Gut Microbiome
  • Irregular Stool 
  • Bad Gas 
  • Effective Nutrient Use  
  • Immune System Support

Combine with Herbsmith Slippery Elm for occasional GI upset & Scooter’s to support bowel health.
