Rabbit Urinary Health

Urinary issues are one of the most common problems in rabbits. From urinary sludge to bladder stones, these conditions can cause pain, infections, and serious complications if left untreated.

Rabbits are prone to urinary problems due to their unique calcium metabolism.
Common issues include sludge, bladder stones, kidney infections, and urinary tract infections.
Diets too high in calcium or poor hydration increase the risk.
Symptoms may range from mild straining to blood in urine or complete urinary blockage.

Why Do Rabbits Get Urinary Problems?

Rabbits absorb most of the calcium from their food, unlike many other animals. Excess calcium is excreted through urine, which makes them more likely to develop urinary sludge or bladder stones if their diet is too rich in alfalfa or certain leafy greens. Poor hydration, stress, obesity, and lack of exercise also increase risks. Infections, genetics, and age can play a role too.

Types of Rabbit Urinary Problems

Urinary Sludge

Thick, creamy urine filled with calcium deposits, often caused by excess calcium or dehydration, irritating the bladder lining.

Bladder Stones (Urolithiasis)

Hard mineral stones form inside the bladder, leading to straining, blood in urine, or urinary blockage.

Urinary Tract Infection (UTI)

Bacterial infection in the urinary system causes painful urination, foul-smelling urine, and frequent accidents.

Kidney Stones or Kidney Disease

Stones in the kidneys or chronic disease cause weight loss, lethargy, and increased thirst.

Symptoms of Rabbit Urinary Problems

Straining to Urinate

Rabbits squat for long periods but produce little or no urine.

Blood in Urine (Hematuria)

Urine appears pink, red, or brown, signaling bleeding inside the urinary tract.

Thick or Sludgy Urine

Urine looks creamy or gritty, leaving chalky deposits in the litter box.

Abdominal Swelling

A bloated belly indicates a bladder blockage that needs urgent care.

Frequent Urination

Rabbits urinate many times a day, but only small amounts come out.

Urine Scald

Wet, irritated fur around the bottom develops from constant urine leakage.

Painful Reactions

Squeaking, grinding teeth, or sudden movements show pain during urination.

Lethargy and Weakness

Rabbits become less active, hide more, and seem tired.

Prevention & Pet Care

Prevention of Health Risks

Keep the rabbit’s living space clean, well-ventilated, and free from dust, smoke, and drafts. A diet rich in vitamin C and fiber supports a strong immune system.

Post-Treatment Monitoring

Watch for sneezing, nasal discharge, or labored breathing. If your rabbit refuses food, breathes with its mouth open, or becomes lethargic, seek urgent care.

Dietary Support

Encourage hay and fresh greens to keep the digestive system active. Syringe feeding or vitamin supplements may be needed if appetite is low.

Limit Stress & Exposure

Separate sick rabbits from healthy ones to prevent spread. Keep the environment quiet and stress-free during recovery.

Long-Term Care

Schedule follow-up visits, as respiratory issues can recur. Avoid dusty bedding and maintain proper hygiene to lower reinfection risk.

Rabbit Urinary FAQ

Rabbits excrete excess calcium in urine. Diets high in alfalfa, spinach, or calcium-rich greens often cause sludge buildup.

No. While mild sludge may pass with hydration, most urinary issues require veterinary treatment to prevent recurrence or complications.

It can indicate bladder stones, infection, or uterine problems in unspayed females. Any blood in urine should be checked immediately.

Yes, especially in middle-aged or overweight rabbits fed calcium-rich diets. Stones may require surgical removal.

Vets may use X-rays, ultrasound, and urine tests to identify stones, infections, or other abnormalities.
