A cat's tail serves a couple of purposes. Mainly, the tail is used for balance, as well as for communication. A broken tail in a cat, known as a sacrocaudal fracture, can occur for a number of reasons, such as accidents, cat fights, and other traumas. Often times, no external wounds are present and, thus, a break in the tail may not be obvious. Nerve damage is often the first sign of a break. You may notice some of the following symptoms: involuntary urine dribbling, dragging of the tail or never holding it high, incoordination of the rear legs, and a dilated, flaccid anal sphincter which may be accompanied by diarrhea or fecal incontinence. Other symptoms that your veterinarian may recognize can include a distended bladder, a painful tail head, loss of sensation in the tail, and bloody urine.
