Cat (Felis catus) — Von Willebrand disease III (hereditary; OMIA-verified species predisposition)

Claims
Species: Cat (Felis catus)Disorder: Von Willebrand disease IIIClin feat: vWD is rarely recognized in cats (Thomas 1996). French et al. (1987) diagnosed von Willebrand disease in a 9-year-old male Himalayan cat. The cat presented with persistent oral bleeding after routine dental extraction. Haematuria (blood in the urine), petechia, melena (black stools due to gastrointestinal bleeding) were also observed. Laboratory testing identified disseminated intravascular coagulation (thrombocytopenia, prolonged activated partial thromboplastin time, and increased fibrin degradation products) and recurring iron-deficiency anemia. Coagulation factor assays revealed low factor VIII coagulant activity and undetectable factor VIII-related antigen. The cat initially recovered after treatment but showed spontaneous gingival bleeding 8 month later. No history of abnormal bleeding existed for the cat's sire or dam.
