  • The American Animal Hospital Association and American Veterinary Medical Association have established guidelines to standardize preventive health care for cats, helping them to live longer, healthier lives. This handout provides an overview of the recommendations within these guidelines and why they are so important.

  • Progressive retinal atrophy (PRA) is a group of degenerative diseases that affect photoreceptor cells in the eyes. With this disease, the cells deteriorate over time, eventually leading to blindness. There are two main forms of PRA recognized in cats, an early-onset, inherited form called retinal dysplasia, and a late-onset form. PRA is an inherited condition in Abyssinian and Persian cats. When a cat develops PRA, it should be removed from the breeding program, along with its parents and siblings. As PRA progresses, your cat's vision gradually worsens until she becomes completely blind. There is currently no effective treatment for PRA.

  • Medical waste includes needles, syringes, body parts, bodily fluids, feces and medications among other things. This handout addresses some of the ways such waste can be safely disposed.

  • Prostatic disease in cats is uncommon and, as a result, relatively little is known about these conditions. Enlargement of the prostate is a common sign with most prostatic diseases and may be noted by your veterinarian on a rectal exam. Other diagnostic tests may be required to determine the cause of your cat's condition.

  • The word enteropathy means any disease of the intestinal system. Protein-losing enteropathy (PLE) is not a specific disease, but rather describes a group of diseases that cause the loss of proteins from the bloodstream into the gastrointestinal (GI) tract.

  • Pulmonary hypertension means that the peak blood pressure in the arteries of the lungs is much higher than normal. Several abnormalities can lead to high blood pressure in the arteries of the lungs and many of the underlying reasons involve the heart. There are many signs of pulmonary hypertension including exercise intolerance, difficulty breathing with or without exertion/exercise, rapid breathing, coughing, spitting up blood from the lungs, fainting, and more. There are many potential causes of pulmonary hypertension. Several medications are available to treat your cat. Activity may need to be restricted. It is essential to monitor cats with pulmonary hypertension for worsening of clinical signs. Periodic physical examinations, blood pressure monitoring, and ultrasound evaluations of the heart are also important. The long-term prognosis is very guarded for cats with pulmonary hypertension.

  • 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.

  • Pulsed electromagnetic field (PEMF) therapy is the use of a generated electromagnetic field to affect changes in tissues of the body. PEMF is believed to have beneficial pain-relieving and healing effects but definitive clinical evidence or a positive benefit is currently lacking. Potential benefits and contraindications are discussed.

  • Pyelonephritis is an upper urinary tract infection involving the kidneys and ureters. Many cats have no clinical signs when they have pyelonephritis, although they may have signs of lower urinary tract disease. Pyelonephritis is usually caused by a bacterial infection that moves up the urinary tract from the bladder to the kidneys. Cats with sudden pyelonephritis do well and return to normal health unless concurrent complications exist.

  • 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.
