Summarize the following:
Your cat's changed behavior might be one of the first signs you notice that alerts you to a tail injury. Your cat may begin dragging his tail or keeping it low to the ground all the time, dribbling urine randomly, or having diarrhea. Your cat may begin walking unevenly or losing coordination in his back legs. Dribbling urine and having diarrhea are not symptoms of a broken tail on their own. If the tail injury was severe enough to cause these signs, the cat will definitely be dragging the tail. Gently feel along the length of the tail. Signs of injury or break include tender, swollen or bent areas. If you notice redness, tenderness, and swelling with fluid underneath, there may be an abscess, or pocket of pus, forming on your cat’s tail. If there is exposed bone or if the skin has been stripped from the tail leaving only bone this is called a ‘degloving’ injury.  If you happen to notice a hard, non-painful kink in your cat’s tail, it’s probably because he was born with the kink in the tail or it's an old, already healed injury.  Never pull or try to remove a severed portion of tail since there are tough tendons and sensitive nerves. If you pull or stretch the tendons, you'll damage the use of the tail, hind limbs, bladder and bowel functions. It may also cause arterial bleeding, which is difficult to control and potentially life-threatening for your cat. The vet can address the injury without additional damage to the tail. Your cat may need a partial or full amputation of his tail if he has a degloving injury, deep cut, or if his tail is deeply or mostly severed. Your vet can also prescribe antibiotics to prevent infection which is highly likely with any open wound. Even if there are no external wounds, the vet can check your cat for other injuries. The vet may find neurologic damage from the tail being pulled during the accident.  The vet will examine the tail for signs of physical or neurological damage. If the vet suspects nerve damage, your cat may have an electromyogram test. Anal sphincter and tail muscles are tested for nerve input. This lets the vet know if the tail will be able to recover. Your cat may still be in pain when you bring him to the vet's office. Stay close to him and speak in gentle comforting tones. You may want to loosely wrap your cat in a towel and place him in his carrier when you bring him to the vet's. This will calm him. Depending on where and how the tail is injured, your veterinarian will determine surgery or another treatment. If the tail is paralyzed, but your cat can still walk, the vet will probably amputate the tail. If the end of the tail has a break that's not causing problems for your cat, the vet may tell you to let it heal on its own.  Your cat may need to stay at the veterinarian's for a few days to either rest and heal, or to determine the extent of the damage to the tail. If your cat's tail must be amputated, don't worry. It may take him a while to adjust to the lack of nerve sensation and change in balance. But, your cat will adapt to the change and his mobility won't suffer in the long run.
Watch your cat's behavior. Examine the cat's tail for injury. Take your cat to the vet if you suspect a tail injury. Understand treatments.
