Cat Constipation: Causes, When to Worry, and When to Seek Care

Constipation in cats occurs when bowel movements become infrequent, difficult, or painful. While occasional changes in stool can happen, ongoing or severe constipation should not be ignored.

Because cats can become uncomfortable quickly—and in some cases develop more serious complications—it’s important to recognize the signs early.

Common Causes of Constipation in Cats

Constipation can be caused by a variety of factors, many of which affect the digestive system or hydration status. Common causes include:

• Dehydration
• Low-fiber diet
• Hair ingestion from grooming (hairballs)
• Obesity or lack of exercise
• Pain or difficulty with posture (arthritis)
• Intestinal blockage
• Pelvic injury or narrowing
• Neurologic conditions
• Chronic conditions such as megacolon

In some cases, constipation may worsen over time if not addressed.

When Should You Be Concerned?

While mild constipation may resolve on its own, certain signs indicate your cat should be evaluated by a veterinarian.

You should seek care if your cat:

• Is straining to defecate
• Has not had a bowel movement in more than 48 hours
• Is producing small, hard stools
• Is vocalizing or showing signs of pain in the litter box
• Has decreased appetite
• Is lethargic or hiding
• Is vomiting

If your cat is unable to pass stool or appears very uncomfortable, prompt care is recommended.

How We Diagnose Constipation in Cats

At Nexus Veterinary Urgent Care, we evaluate constipation by identifying the underlying cause and determining the severity.

Diagnostics may include:

• Physical examination and abdominal palpation
• Review of diet, hydration, and litter box habits
• X-rays to assess stool buildup or obstruction
• Bloodwork if underlying disease is suspected
• Additional testing depending on findings

Our goal is to determine whether the issue is mild or requires more advanced care.

Treatment Options

Treatment depends on the cause and severity of your cat’s constipation.

Common treatments may include:

• Fluid therapy to improve hydration
• Stool softeners or laxatives
• Dietary changes (increased fiber or prescription diets)
• Hairball management
• Enemas (performed by a veterinarian when needed)
• Treatment of underlying conditions

More severe or chronic cases may require ongoing management.
