Chitosan and alginate have the capacity to absorb the secretion, to stimulate collagen production and to restore tissue lesions, and were proved to be biocompatible and biodegradable. This article describes the treatment of an open infected bite-injury located on the right side of the abdominal-chest region, with subcutaneous-tissue loss, in a cat. Chitosan and chitosan-alginate films developed in the Department of Biotechnological Process of the Chemical Engineering School of the State University of Campinas (Unicamp) were used to cover the wound. These film dressings were changed at intervals of 48, 72 hours, and at 4, 7, 14, 21, and 24 days. On the 30th day the patient was released. Facing the satisfactory evolution of the injury, one may conclude that both films were effective for the treatment of the described case, leading to a healthy granulation reconstruction of the tissue, and to quick healing and scaring within 30 days.
