Pleural effusion refers to the abnormal accumulation of fluid within the chest cavity. The fluid is not found within the lungs, but instead within the pleural sac, essentially meaning the lungs are floating in a chest that is full of fluid. Several conditions can cause pleural effusion, including chylothorax, heart failure, and tumors in the lungs or chest wall. Immediate treatment often requires oxygen support and the removal of the excess fluid by thoracocentesis, which can also then be tested to diagnose the cause of the pleural effusion. Treatment and prognosis vary depending on the underlying cause of the pleural effusion.

Pulmonary thromboembolism describes a condition in which a blood clot lodges in one of the pulmonary arteries, blocking blood flow into the portion of the lung served by that artery. The signs of pulmonary thromboembolism include sudden difficulty breathing, rapid breathing, decreased appetite, fainting, coughing, spitting up blood, weakness, exercise intolerance, and the inability to get comfortable. Sudden death is possible. This article discusses potential causes, treatment, and prognosis.

Pyometra is a serious and life-threatening infection in the uterus, occurring in female cats who have not been spayed. The condition must be treated quickly and aggressively. The preferred treatment is to surgically remove the uterus and ovaries by performing an ovariohysterectomy. There is a medical approach to treating pyometra, although the success rate is highly variable and not without considerable risk and potential long-term complications.
-
Pyothorax is the presence of inflammatory fluid or pus within the chest cavity, which is the area between the lungs and the inner walls of the ribs. Signs of pyothorax include rapid, shallow, open-mouthed breathing that may be painful, depression, lethargy, decreased appetite. Clinical examination by a veterinarian, particularly listening to the chest with a stethoscope, may indicate fluid in the chest.

Pyrethrin insecticides are naturally derived from the chrysanthemum (mum) flower, and pyrethroids are the synthetic versions. The use of pyrethrins/pyrethroids is generally safe in dogs; however, cats and fish are very sensitive to these products.

Retinal detachment can cause sudden blindness or vision changes. It is generally secondary to an underlying condition like high blood pressure. Diagnostics and treatment are discussed. Prognosis is guarded to good depending on the underlying cause.

Sago Palms are pretty plants but beware—they pack a deadly punch for pets. The popular Sago Palm enhances outdoor landscapes in warmer areas of the U.S. and serves as indoor decor in many colder climates. All parts of the Sago Palm are poisonous, but the seeds (nuts) are the most toxic to pets. As with all poisoning cases, early detection and treatment increases the rate of success.

A seizure is a sudden surge in the electrical activity of the brain causing signs such as twitching, shaking, tremors, convulsions, and/or spasms. Epilepsy is used to describe repeated episodes of seizures. With epilepsy, the seizures can be single or may occur in clusters, and they can be infrequent and unpredictable or occur at regular intervals. Since many different diseases can lead to seizures, it is important to perform diagnostic tests to investigate the underlying cause of the seizures. Treatment of seizures in the cat depends on the nature of the underlying disease.
-
Smoke inhalation injuries are caused by a combination of heat and airborne toxins. Clinical signs of smoke inhalation vary, depending on the materials contained within the smoke and how much smoke the cat inhales. Common signs include coughing, shortness of breath, eye injuries, and burns. Neurologic signs can also occur, especially in cases of carbon monoxide inhalation. Treatment typically involves oxygen therapy and other supportive care measures.

Strokes are rare in cats. Some causes include a blood clot such as a thrombus or embolus that lodges in a cerebral blood vessel, cerebral bleeding from trauma, or a blood clotting disorder; however, the cause is often unknown. Signs of a stroke are variable depending on the regions of the brain affected and the degree and duration of blood and oxygen deprivation. Magnetic resonance imaging is the ideal diagnostic test for diagnosing a stroke. Treatment is complex and there is no guarantee of complete success. Your veterinarian will help you assess progress and plan remedial action.
