What is cat tail falls off?

Cats typically shed their tails as a defense mechanism when they are in a traumatic or dangerous situation. This is called autotomy, where an organism purposely sheds a body part to escape from a predator or other danger. However, if a cat's tail falls off due to injury, it can be a serious problem and may result in nerve damage or infection. It is important to monitor your cat's tail for any signs of injury or infection and seek veterinary attention if needed. Some common causes of tail injuries in cats include getting caught in doors, getting grabbed or bitten by another animal, or being hit by a car.
