This is a common problem in rabbits and can be tricky to treat as there are a number of reasons that can cause this. The most commonly problems are incontinence and urine scalding and sludgy bladder disease, which means that either too much or too little urine is being produced at times.
Kidney or bladder stones (urolithiasis) and sludgy urine are the common urine tract disorders which occur because of a diet rich in calcium, less water intake and little exercise. Your bunny will develop thick and white urine, of almost tooth-paste like consistency at times.
Cystitis is an inflammation or the urinary bladder that can cause frequent urination – a burning sensation and can cause sludgy urine. This is often caused by a bacterial infection, which can be treated by antibiotics.
Urine scalding is a problem that is seen in bunnies that lived in damp conditions, or passing down urine not in the correct position so it dribbles down the inside of the leg and the underside of the tail. A bunny’s urine is corrosive and is an irritant so it can make the skin very sore if it’s in contact and if the bunny is not able to clean itself.
