Rabbit Urine Scald: Causes, Treatment, and Prevention

If the fur around your rabbit's hindquarters is yellowed, wet, or losing hair, you may be seeing urine scald — one of the most uncomfortable but common conditions exotic vets treat. In 2026, the House Rabbit Society continues to emphasize that urine scald is rarely just a hygiene problem. It almost always means something else is wrong, and the skin damage is just the first thing you notice.

What Is Urine Scald?

Urine scald (also called urine dermatitis) is inflammation, redness, and breakdown of the skin caused by chronic contact with urine. In rabbits, this most often shows up on the:

• Belly
• Inner thighs
• Around the genitals and anus
• Back paws (rabbits sit in urine when they can't move freely)

The urine's ammonia content damages the skin barrier, and the constant moisture invites bacterial and yeast infections.

Why Is My Rabbit Soaking in Her Own Urine?

A clean, healthy, mobile rabbit does not get urine scald. The presence of scald almost always means something is preventing normal urination posture or hygiene.

Common Underlying Causes

Urinary disease

• Bladder sludge or stones
• Urinary tract infection
• Urinary incontinence (E. cuniculi, spinal injury)

Mobility problems

• Arthritis or hind-leg weakness
• Obesity preventing the rabbit from raising her hindquarters
• Spinal injury or paralysis
• Severe pododermatitis (sore hocks)

Environmental issues

• Cage too small to step away from urine
• Soiled bedding left too long
• Wire cage floors that cause foot injuries

Neurological causes

• Encephalitozoon cuniculi (E. cuniculi) — a parasitic infection causing weakness and incontinence
• Head tilt or vestibular disease

Signs of Urine Scald

• Yellow, orange, or brown staining of fur around the hindquarters
• Damp, sticky fur in those areas
• Red, raw, or weeping skin
• Foul ammonia smell
• Loss of fur in the affected areas
• Visible skin sores, scabs, or crusty patches
• Maggots in severe outdoor cases (flystrike — a life-threatening emergency)
• Reluctance to move or hop

When To Worry

See an exotic vet within 24 hours for:

• Raw or broken skin in the affected area
• Smell of infection
• A rabbit who has stopped grooming herself
• Combined symptoms of weakness, head tilt, or incontinence
• Sudden onset of urinary changes

Go to an emergency exotic vet right away if you see maggots, fly eggs (small rice-grain looking clusters), or your rabbit is collapsed and very weak. Flystrike kills within hours.

How to Treat Urine Scald at Home

Treatment must address both the skin damage and the underlying cause.

Clean and Dry the Skin

• Trim away soiled fur with blunt-tipped scissors (be very careful — rabbit skin tears easily)
• Bathe the affected area only with warm water and a vet-approved gentle cleanser. Do not full-bath a rabbit — wet rabbits chill rapidly and can go into shock.
• Pat dry thoroughly with a soft towel; consider using a hair dryer on cool, low setting at a safe distance
• Keep the rabbit somewhere clean and dry to recover

Topical Care

Ask your vet for an appropriate barrier cream or topical treatment. Do not apply human creams (especially anything containing zinc, salicylic acid, or steroids) without veterinary direction — rabbits ingest topicals during grooming.

Address the Cause

Treating the scald without fixing the underlying problem only buys time. Work with your vet to investigate:

• Urine analysis and bladder imaging
• Spine and limb evaluation
• E. cuniculi testing (blood titer)
• Weight management plan if obese

Prevention

• Daily spot-cleaning of litter box and any soiled bedding
• Litter box training — most rabbits litter-train well; offer multiple litter pans in larger enclosures
• Soft, absorbent bedding — avoid wire floors
• Weight management — keep a slim body condition; obese rabbits cannot reach to groom
• Move arthritic rabbits regularly, with low-step litter pans and non-slip flooring
• Annual exotic vet checks, especially as your rabbit ages

Frequently Asked Questions

Q: Can urine scald heal on its own? A: Mild irritation may resolve once urine contact stops, but moderate to severe scald usually requires veterinary care and addressing the underlying cause.

Q: How can I tell urine scald from regular wet fur? A: True urine scald involves redness, skin damage, fur loss, and odor. Normal wet fur from a single mishap dries without skin damage.

Q: Is urine scald painful for rabbits? A: Yes. The skin breakdown can be severely painful, especially when bacterial infection sets in. Rabbits often hide pain — look for changes in posture and appetite.

Q: My older rabbit suddenly has urine scald — why? A: Older rabbits often develop arthritis, weakness, or bladder issues. Get her examined — addressing pain or mobility issues may resolve the scald entirely.

Q: What is flystrike and how is it connected? A: Flystrike is when flies lay eggs on soiled or wet rabbit fur, and the hatching maggots feed on the rabbit's skin. It's a true emergency, usually fatal within hours. Daily inspection of the hindquarters in warm weather is essential.
