Hair Balls

Although most hair balls are hair today and gone tomorrow, some are longer lasting and much more dangerous. Sometimes even normal size hair balls can cause intestinal blockage or choking. If the retching continues for more than three days or if your cat is constipated or refuses food for more than a day, it is recommended that you take the animal to a vet. A hairball that blocks the digestive tract can be deadly, so catching it early is important.
