The cat's tail is drooping, motionless and painful when touched, which may be caused by a fracture. You need to take the cat to the pet hospital for examination and treatment to avoid delaying the treatment opportunity. At the same time, the cat must be supplemented with calcium to help the cat recover better. Pay attention to avoid injury to the cat's tail, especially when closing the door or cabinet. It is easy to get the cat's tail caught. Once caught, check the cat promptly to see if it is injured.
