Rectal prolapse in hamsters is the protrusion of a red-pink fleshy tube of intestinal tissue through the anus, almost always secondary to straining from diarrhea, severe parasitism, intussusception, or proliferative ileitis (wet tail). It is an emergency — prolapsed tissue dries, becomes ischemic, and necroses within hours. Prompt exotic veterinary care with reduction, purse-string suture, and treatment of the underlying cause gives many hamsters a reasonable prognosis when caught early (AEMV Pet Care Guides, 2024).

What Rectal Prolapse Actually Is
Rectal prolapse is the eversion of one or more layers of rectum or distal colon through the anal opening. In hamsters the tissue appears as a glistening pink to red cylindrical mass, ranging from a small button to several centimeters of protruding tissue. As the prolapse persists, tissue swells, darkens, and dries — by 6 to 12 hours of exposure to air, ischemic injury becomes significant. Untreated prolapse leads to tissue necrosis, sepsis, and death within a day or two in most cases.
Why It Happens
Rectal prolapse is a sign rather than a primary disease. The most common drivers in pet hamsters are: proliferative ileitis (wet tail) in young Syrian hamsters, which causes severe diarrhea and straining; severe pinworm or other intestinal parasite burden; intussusception of the distal colon; and chronic diarrhea from inappropriate diet, sudden food change, or bacterial enteritis. As described in Quesenberry & Carpenter's Ferrets, Rabbits & Rodents, identifying and treating the underlying cause is essential — surgical reduction without addressing the cause leads to recurrence within days.
Initial Home First Aid Until You Get to the Vet
If you find a prolapse, keep the tissue moist with sterile saline or clean lukewarm water and a soft damp cloth. Do not attempt to push it back at home — replacement without correct technique can cause further tissue damage. Place the hamster in a quiet warm carrier with a soft damp cloth covering the prolapsed tissue and contact an exotic vet immediately. Do not delay overnight. The window for successful reduction is roughly 6 to 12 hours.
Veterinary Treatment
Initial vet treatment usually involves: sedation and pain control, gentle cleaning of the prolapsed tissue, application of hypertonic sugar or dextrose to reduce edema, manual reduction back through the anus, and placement of a temporary purse-string suture to prevent immediate re-prolapse. The purse-string is sized to allow stool passage and is removed in 5 to 7 days. Fluids, antibiotics targeting enteric pathogens, and a syringe-feed soft diet support recovery. Severely necrotic prolapses require partial colectomy at a specialty exotic surgical center — a major procedure with guarded prognosis in a small mammal.
Treating the Underlying Cause
After reduction, the cause must be addressed or recurrence is the rule. For suspected wet tail in a young Syrian hamster, antibiotics targeting Lawsonia intracellularis (oxytetracycline, doxycycline, or chloramphenicol) plus aggressive fluid support are standard. For pinworms, fenbendazole or ivermectin clears the parasitism. For chronic diarrhea from diet, a slow transition to a high-fiber pellet diet with limited fresh veg is appropriate. Probiotic support is reasonable as an adjunct. Broader supportive care principles for small-mammal GI emergencies are outlined in current exotic mammal husbandry guidance (AEMV Pet Care Guides, 2024).
When to See a Vet
Call your vet today if:
- Any pink or red fleshy tissue visible at the anus
- New or worsening diarrhea, especially in a young Syrian hamster
- Repeated straining at the litter or in the cage
- Soft or watery stool for more than 24 hours
- New diet change followed by loose stool
Go to the ER immediately if:
- Pink, red, or purple tissue visibly protruding from the anus — this is the condition
- Prolapsed tissue that has become dark, dry, or appears dead
- Active bleeding from the anus
- Hamster cold to the touch, unresponsive, or limp
- Profuse watery diarrhea with collapse

Frequently Asked Questions
Can I push the prolapse back in myself?
Strongly recommended against. Even if you reduce the tissue temporarily, the underlying cause is still driving straining and the prolapse will recur immediately. Worse, replacement without sedation, proper analgesia, and a retaining suture damages the tissue and rapidly worsens the prognosis. Keep the tissue moist and get to an exotic vet within hours.
How much does rectal prolapse treatment cost?
Initial exotic emergency exam typically runs $100 to $300, since exotic emergency pricing runs about 1.5 to 2 times standard plus emergency premium. Sedation and prolapse reduction with purse-string suture runs $300 to $700. Hospitalization for fluid support is $200 to $500 per day. Diagnostics for underlying cause (fecal, bloodwork, abdominal radiographs) add $200 to $500. Surgical colectomy at a specialty center runs $1,500 to $3,500+. Catching wet tail or parasites before prolapse develops is dramatically cheaper.
My hamster is a baby and has wet diarrhea — is prolapse next?
Possibly. Young Syrian hamsters with proliferative ileitis (wet tail) frequently develop rectal prolapse from straining if not treated within the first 24 to 48 hours of diarrhea. Wet tail is itself a high-mortality disease in young hamsters and is an emergency in its own right. Seek exotic vet care immediately for any young Syrian hamster with watery diarrhea, sticky wet rear fur, lethargy, and reduced appetite.
What is the survival rate after treatment?
Outcomes depend on duration of prolapse and underlying cause. Simple prolapses caught within 6 hours from treatable diarrhea or parasitism have a good prognosis with appropriate care. Severe prolapses with necrotic tissue, those caused by intussusception, and those in young hamsters with severe wet tail carry guarded to poor prognoses. Recurrence within days of reduction is common when the underlying cause is not addressed.
Could feeding the wrong food cause this?
Sudden dietary changes, high-sugar fruits, lettuce in large amounts, and inappropriately rich treats can produce diarrhea severe enough to cause straining and prolapse. A standardized commercial hamster pellet supplemented with small amounts of safe vegetables is the safer routine. After recovery, reintroduce any new foods gradually over 7 to 10 days.
