If you notice your cat straining to defecate, tiny or hard feces and/or not defecating for days you may need to investigate. Cats with constipation or obstipation may exhibit the following signs:

  • Infrequent or no defecation
  • Defecating outside the litter box
  • Small quantities of feces
  • Small amount of liquid stool with mucus or blood
  • Vomiting
  • Lack of appetite
  • Straining to defecate
  • Hard, dry feces
  • Depression

Veterinarians may be able to feel your cats belly to detect firm feces in the intestines. In overweight cats, however, abdominal fat can limit a veterinarian’s ability to feel fecal material in the intestines. In these cases, an x-ray may be necessary to assess the problem. In the case of obstipation or megacolon, the colon will be greatly stretched beyond its normal size.

On occasion an endoscopic exam may be necessary. Anesthesia is required for this procedure and a tube is inserted in the rectum, containing a small camera. This allows the veterinarian to look inside the rectum and colon for abnormalities such as narrowing of the colon or tumors that may prevent feces from passing. A biopsy of the tissue may also help identify other health issues that are causing constipation. Your Veterinarian may also recommend blood work to look for underlying diseases that may cause dehydration leading to constipation.


Treatments for your cats constipation can vary, depending on the degree of constipation and the amount of discomfort. If  the constipation is mild, your veterinarian may supplement your cat’s diet with fiber, such as canned pumpkin, bran or psyllium. Other medications, such as stool softeners, laxatives and motility modifiers, may help, as well. If a health condition, like kidney disease, is causing dehydration and constipation, treating the problem and re-hydrating your cat will help. Increasing water consumption is key to help constipation in cats and always provide multiple fresh water sources. You can try a dripping faucet or a continuous flow cat water fountain. If your cat eats dry food consider switching to wet food to increase his water intake. For more severe forms of constipation an enema may be necessary.

If your cat is diagnosed with megacolon, the diameter of the colon can sometimes be stretched so far that the muscles of the digestive tract are permanently damaged. If this happens, surgical removal of the affected portions of the colon may be necessary to save your cat’s life.


Most cats with constipation problems can be managed without surgery and they will continue living normal, healthy lives. If your cat requires surgery to correct the mega-colon, the prognosis is good. Whatever the cause, do not ignore your cats’s constipation.
