- Calciuria, or calcium carbonate sludge, is a common finding in the urinary bladder of the rabbit, which occasionally may lead to a variety of urinary symptoms. Rabbits, unlike most mammals, eliminate almost all of their calcium through the urine (unlike most mammals who eliminate significant amounts within the bile.) Any additionaly increases in dietary calcium may worsen this problem. It is not uncommon to see a little "sludge" in the bladder of normal rabbits at autopsy - this amount is abnormal and may lead to cystitis or persistent dilation and atony.
