Introduction & Key Takeaways

Rectal prolapse happens when part of the rectal lining protrudes through the anus — a result of straining, diarrhea, parasites, or other intestinal issues. Prompt action is essential to prevent tissue damage and lasting complications.

• 📌 Recognize early signs: visible tissue, straining, mucus/blood.
• ⚠️ Causes include diarrhea, constipation, parasites, tenesmus, and GI inflammation.
• 🔍 Diagnosis via exam, fecal tests, imaging, and sometimes endoscopy/biopsy.
• 🩺 Treatments range from manual reduction to surgery (purse-string, resection, mucosal resection).
• 📈 Aftercare: stool softening, diet, antibiotics, limited activity.
• 🚫 Prevention involves parasite control, managing diarrhea, fiber supplementation, and regular vet checkups.

1. What’s Rectal Prolapse?

This occurs when intestinal wall layers protrude through the anus. It’s classified by depth: mucosal-only, mucosa/submucosa, or full-thickness including muscular layers — with severity guiding treatment options.

2. Underlying Causes

• 💩 Chronic diarrhea or constipation
• 🪱 Intestinal parasites (Giardia, whipworms, hookworms)
• 🫁 Gastrointestinal inflammation: colitis, IBD
• 🩵 Tenesmus: straining from cystitis, prostatitis, constipation
• 🌡️ Fever or systemic illness causing tissue edema

Lasting straining weakens pelvic and anal supporting tissues, leading to prolapse.

3. Signs & Severity

• 🔴 Visible pink/red tissue protruding
• 📌 Straining, urgency to defecate
• 💧 Mucus, fresh blood
• 😾 Discomfort: vocalization, restlessness, licking
• ⚠️ Potential swelling, necrosis, infection if untreated

4. Diagnosing the Problem

1. History: Recent diarrhea/parasites, diet changes
2. Visual/physical exam: Assess tissue viability, swelling, tension
3. Fecal tests: Parasites, Giardia, inflammatory cells
4. Bloodwork: Check hydration, infection, inflammation
5. Imaging: Abdo X-rays or ultrasound for masses, GI obstruction
6. Advanced tools: Endoscopy/rectal biopsy for IBD or tumors

5. Treatment Approaches

Manual Reduction

If caught early and tissue is viable, the vet can gently reduce prolapse under light sedation, lubricating tissue, and applying topical anti-inflammatory.

Purse‑String Suture

A non-absorbable suture encircling the anus prevents recurrence while allowing small stool passage; removed after 5–7 days.

Surgical Resection & Anastomosis

Indicated for necrotic or full-thickness prolapse. The damaged segment is removed and intestines reconnected. Followed by antibiotics, stool softeners, and bed rest.

Mucosal Sleeve Resection

Used when only the mucosal layer prolapses; reshapes tissues and prevents recurrence.

Colopexy/Colostomy

Rarely used in recurrent or obstructive GI disease; attaches colon to abdominal wall or relocates it.

6. Aftercare & Recovery

• 💊 Stool softeners (lactulose), mild fiber diet
• 🧼 Topical antibiotic and anti-inflammatory ointment on the anus
• 🩺 Antibiotics to prevent recurrence
• ✅ Benign high-fiber diet for 4–6 weeks to minimize straining
• 🩹 Prevent licking with E-collar or recovery suit
• 🐾 Restrict activity and litter-box access for 10–14 days
• 📅 Recheck in 7 days to assess suture removal and healing

7. Prognosis & Monitoring

• 📈 Early intervention → excellent outcome
• ⚠️ Delayed or severe cases may lead to stricture, incontinence, or abscess
• 🔄 Recurrent cases require diagnostics (parasites, IBD, tumors) to address cause
• 🔁 Monitor stool quality, straining, appetite, activity

8. Prevention Tips

• 💊 Keep parasite prevention, especially in outdoor cats
• 🍲 High-fiber, digestive-supportive diet
• 🚫 No access to foreign objects prone to ingestion
• 📞 Quickly address diarrhea, straining, constipation
• 📱 Use the Ask A Vet app to track litterbox habits & get advice early

9. FAQs

Is prolapse always emergency?

Yes — even small prolapse can deteriorate quickly. Immediate vet treatment reduces the risk of necrosis.

Can a small prolapse heal alone?

Sometimes self-reduces in mild cases but often recurs. Veterinary exam is safest.

How soon can cats use the litterbox again?

Use high-sided box with soft substrate; usually resumes around day 3 post-suture, supervision needed.

Will kitty have bowel control issues after surgery?

Rarely. Gentle handling and early intervention help preserve anal sphincter function.

10. Supporting Your Cat

• 📍 Log stool frequency, consistency, presence of blood
• 🛏 Provide soft bedding, low stress environment
• 💧 Keep water accessible to prevent constipation
• 🔄 Administer all meds, monitor appetite and energy
• 📱 Use Ask A Vet app for photo consultations and check-in reminders

Conclusion

Rectal prolapse is a serious condition that requires prompt veterinary care. With early treatment, aftercare, and preventative habits like parasite control and fiber diet, most cats fully recover and lead healthy lives.
