ASPCA logo Constipation-difficult or infrequent bowel movements-is one of the most common health problems associated with a pet’s digestive system. Cats usually have at least one healthy bowel movement every day. But if your cat is passing dry, hard stools, straining when trying to defecate or making unsuccessful trips to the litter box, please see your veterinarian. These symptoms may indicate an underlying health problem.

How Can I Tell if My Cat Is Constipated

If your cat suffers from any of the following symptoms, please consult your veterinarian. These signs may also be symptoms of urinary disorders, so it’s important that your vet helps you to determine the cause right away:

  • Straining or crying out in pain when trying to eliminate
  • Small, dry, hard stools, possibly covered in mucous or blood
  • Frequent, unproductive trips to the litter box
  • Loss of appetite
  • Weight loss
  • Lethargy
  • Vomiting
  • Displays of abdominal discomfort
  • Lack of grooming

What Causes Cats to Become Constipated

There are many reasons why your cat may have trouble eliminating:

  • Low-fiber diet
  • Dehydration
  • Hairballs/excessive grooming
  • Blocked or abscessed anal sacs
  • Enlarged prostate gland
  • Tangled hair on the buttocks
  • Ingestion of foreign objects such as string, cloth, bones, etc.
  • Side effect of medication
  • Tumor or other intestinal obstruction
  • Neurologic disorder
  • Obesity
  • Abnormal colon shape or motility

How Can I Treat My Cat's Constipation?

Depending on what’s causing your cat’s constipation, your vet may recommend one or several of the following treatments: (Never give your cat medications without discussing it with your veterinarian first.)

  • Stool softener
  • Laxative
  • Enema (administered by a professional, not at home, please). It is important to note that cats do not take kindly to these procedures, and some over-the-counter enemas contain substances that can be toxic to cats. This is a procedure best left to your veterinarian.
  • Medication to increase the contractile strength of the large intestine
  • Manual evacuation of the bowels
  • Surgery to remove obstruction in the bowels
  • Veterinarian-prescribed, high-fiber diet
  • Adding fiber to your cat’s diet with canned pumpkin, bran cereal or a product such as Metamucil
  • Increase in water consumption
  • Increase in exercise
