The Appearance of Rabbit Urine ------------------------------ Urine from normal rabbits usually contains large amounts of a light-colored sediment and may appear abnormal to the uninitiated. The color of normal rabbit urine varies from white, to yellowish-white, to light brown. Rabbits that drink large quantities of water tend to produce clearer urine containing less sediment. Rabbits that have been recently treated with antibiotics and those undergoing significant stress may temporarily produce urine that is orange or red-tinged. Such urine can be differentiated from that which accompanies urinary tract infections or uterine bleeding by use of a urinalysis, performed by a veterinarian.
