<p>The present report describes the first clinically manifested and serologically proven case of <italic>Dirofilaria immitis</italic> infection in a cat in Bulgaria. A 10-year-old intact male cat was referred to the Small Animal Clinic, Trakia University with a history of anorexia, weight loss, intermittent coughing and itching skin lesions on the head and neck. Physical examination revealed abnormal heart sounds and respiration, cyanosis of the mucous membranes, and generalized enlargement of the lymph nodes.

Blood serology revealed antigens of <italic>D. immitis</italic> as well as antibodies against both feline immunodeficiency virus and <italic>D. immitis</italic>. Thoracic radiographic findings included a pronounced generalized reticular interstitial pattern; alveolar and bronchial shades with multiple nodular thickenings throughout the lungs. Electrocardiography demonstrated a sinus tachycardia, a peaked P-wave (P-pulmonale) and an abnormally low ST-segment.
