Rarely, ovarian tissue can be left behind when a cat is spayed. This leads to the ongoing secretion of hormones such as estrogen and progesterone that can result in a cat continuing to have a heat cycle. Ovarian remnants are difficult to diagnose but vaginal cytology, combined with hormone testing, can be used to confirm the presence of functional ovarian tissue. Surgical treatment is typically recommended to prevent other health conditions from developing.

Pandora syndrome affects multiple organ systems, including the urinary tract. The term is often used synonymously with Feline Idiopathic Cystitis (FIC), but FIC is only one component of Pandora syndrome. It is believed to be related to chronic stress.

Patent ductus arteriosus (PDA) is a heart defect that occurs when the ductus arteriosus (an opening between the aorta and the pulmonary artery) fails to close at birth. A PDA is usually diagnosed when your veterinarian hears a continuous heart murmur during a routine physical examination of your puppy. This article explains PDA and discusses signs, treatment, and prognosis for this condition.

Pemphigus is an autoimmune skin disease in which the body's immune system attacks the connections between its own skin cells. The three most common types of pemphigus are pemphigus foliaceus, pemphigus vulgaris, and pemphigus erythematosus. Treatment requires suppression of the immune system and prognosis varies depending on the type.

Pericardial effusion refers to the abnormal accumulation of fluid in the sac surrounding the heart. Pericardial effusion can have a number of underlying causes, including inflammation, infection, cancer, and hereditary defects. Mild cases of pericardial effusion may be asymptomatic, but more significant fluid accumulations can interfere with the heart’s function and lead to severe effects such as sudden death. Treatment and prognosis is dependent upon the underlying cause of the condition.

Pigmentary keratitis is a discoloration of the cornea due to chronic inflammation and is most common in brachycephalic breeds. In many cases, complete resolution cannot be achieved, but the condition can be stopped or slowed down if the underlying cause can be identified and treated. Surgery and medications may be used to help address the problem.

Pituitary macroadenomas are large tumors of the pituitary gland that are either functional (secrete hormones) or non-functional (do not secrete hormones). The clinical signs depend on the type of macroadenoma, though become severe over time in either case. Diagnosis requires specialized CT or MRI imaging. This handout explains the effects of macroadenomas in cats and the treatment options available.
