Background: Pyothorax in cats is treated with intravenous fluids and antibiotics, and while thoracotomy and debridement are less commonly necessary, thoracostomy tubes are the treatment of choice when repeated drainage of the pleural cavity is needed. 
Case Description: An 11-month-old British short-haired cat was presented for a sudden onset of lethargy, dyspnea, and tachypnea, following an ovariohysterectomy 10 days prior to the treatment process. Pyrexia and muffled cardiac sounds on the left hemithorax were noted. A hemogram indicated the development of anemia and neutrophilia with a left shift. Radiography and ultrasonography confirmed a pleural effusion, and a CT scan ruled out the presence of any masses or perforating foreign bodies. A PCR on the pleural effusion ruled out feline coronavirus infection, and fluid analysis was confirmed as a septic exudate with Pasteurella multocida infection. A pleural access port was used to treat the pyothorax that successfully reduced hospitalization time and lowered overall financial outlay despite surgical implantation. 
Conclusion: The present report describes the successful use of a pleural port to treat pyothorax in one cat. This is the first time such a device has been reported for the treatment of pyothorax.
