If blood loss is severe, your pet will be hospitalized and will receive blood and plasma transfusions. In fact, repeated transfusions may be necessary to control or prevent further hemorrhaging. Your veterinarian will probably also prescribe vitamin K, especially if your pet has ingested rodent poison or is experiencing other conditions that deplete this vitamin.
Your doctor will continue to test your cat's blood on an ongoing basis to determine the effectiveness of vitamin K supplementation, if it has been prescribed. It should begin to normalize 24 to 48 hours after the beginning of therapy. The only way to test whether a hereditary deficiency has been treated successfully is by factor analysis; whether the hematomas (collections of clotted blood) have been resolved, and most importantly, whether the bleeding has stopped. Transfusion sometimes causes immune reactions when antibodies resist the new blood. If transfusion is a decided treatment, your pet will need to be monitored for symptoms of rejection.
There is no particular breed that is more susceptible than another, so there is nothing that can be done to prevent it unless it is known to be in the genetic makeup of your cat's family line. If it is determined that a hereditary factor is responsible for the coagulation factor deficiency, it is best not to breed this animal.
