Rabbit Incontinence: Causes of Leaking Urine or Loss of Bladder Control

Urine leaking in rabbits often happens because something is irritating the bladder or making it hard for the rabbit to empty the bladder normally. Common urinary causes include urinary tract infection, bladder sludge from thick calcium-rich sediment, and bladder stones. These problems can lead to dribbling, frequent small urinations, straining, strong-smelling urine, blood in the urine, or wet fur on the hind legs and around the tail. Rabbits with sludge may also have sandy or gritty urine and painful urine scald on the skin.

Not every rabbit that seems incontinent has a primary bladder problem. Arthritis, obesity, sore hocks, weakness, or poor mobility can make it hard for a rabbit to posture correctly to urinate, so urine ends up on the fur instead of in the litter box. Spinal injury or neurologic disease can also reduce bladder control. In female rabbits, blood or discharge from the reproductive tract can sometimes be mistaken for urinary disease, so your vet may need to sort out where the fluid is coming from.

A wet rear end can also be made worse by urine scald, where constant moisture irritates the skin and causes redness, hair loss, odor, and pain. Once the skin is inflamed, rabbits may lick more, move less, and become even harder to keep clean. That is why ongoing leaking should not be written off as a litter box issue, especially in an older rabbit or one that seems stiff or uncomfortable.

See your vet the same day if your rabbit is straining to urinate, passing only drops, crying out, hunched, grinding teeth, has a swollen belly, or stops eating. Those signs can happen with severe bladder pain, obstruction, or advanced sludge and stones. Blood in the urine, marked lethargy, or a sudden soaked hind end also deserves prompt attention.

You should also book a visit soon if the leaking has been happening for more than a day, your rabbit has urine scald, the urine looks thick or sandy, or your rabbit is missing the litter box despite previously good habits. Rabbits often hide pain, so mild-looking urinary signs can still reflect significant discomfort.

Brief monitoring at home may be reasonable only if your rabbit is otherwise bright, eating normally, passing normal amounts of urine, and the wetness seems mild and short-lived. Even then, keep the area clean and dry, watch appetite and droppings closely, and contact your vet if the problem returns. If you are unsure whether the issue is urine, diarrhea, or reproductive discharge, it is safest to have your vet examine your rabbit.

Your vet will start with a careful history and physical exam. They will want to know when the leaking started, whether your rabbit is straining, what the urine looks like, whether there is blood or odor, and whether your rabbit has had mobility changes, weight gain, or trouble grooming. The exam often includes checking the bladder size, feeling for stones, looking for urine scald, and assessing the spine, hind limbs, and overall hydration.

Common tests include a urinalysis to look for blood, inflammatory cells, crystals, and urine concentration, plus a urine culture if infection is suspected. Many rabbits also need X-rays because bladder sludge and stones are often visible on radiographs. In some cases, your vet may recommend ultrasound, bloodwork, or both to check kidney function, hydration, and whether another illness is contributing.

Treatment depends on the cause. Your vet may discuss pain control, fluids, antibiotics when infection is confirmed or strongly suspected, skin care for urine scald, diet and hydration changes, bladder expression or flushing in selected cases, and surgery if there is a large stone or obstruction. If arthritis, obesity, or neurologic disease is part of the problem, the plan may also include mobility support and changes to the home setup.

Home care focuses on keeping your rabbit clean, dry, eating, and comfortable while your vet works on the cause. Gently clean soiled fur with rabbit-safe guidance from your vet, then dry the area well. Replace damp bedding often, use soft absorbent materials, and consider a low-entry litter box if your rabbit is older, arthritic, or weak. Check the skin at least once daily for redness, hair loss, odor, or sores.

Encourage normal hydration and hay intake unless your vet recommends otherwise. Good hydration can help support urinary flow, and steady eating is essential for rabbit gut health. Watch for appetite changes, smaller droppings, hiding, tooth grinding, or reluctance to move, since those can signal pain.

Do not start leftover antibiotics, human creams, or over-the-counter pain medicines on your own. Some products are unsafe for rabbits, and the wrong medication can delay proper treatment. If your rabbit becomes more lethargic, stops eating, strains, or seems unable to pass urine, see your vet immediately.
