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.

The pancreas is a vital organ on the right side of the abdomen adjacent to the stomach. It produces enzymes to assist in food digestion and hormones such as insulin, which regulates blood sugar or glucose metabolism. When the pancreas becomes inflamed, the condition is called pancreatitis. Common clinical signs include decreased appetite, nausea, vomiting, lethargy, diarrhea, and abdominal pain. If the attack is severe, acute shock or death may occur. Successful pancreatitis management will depend on early diagnosis and prompt medical therapy.

Pancreas-specific lipase is a form of lipase produced only in the pancreas and is highly specific to the pancreas. Blood values increase only when there is pancreatic inflammation. There is now a version of the fPLI test that can be used in-clinic (SNAP fPL© from IDEXX). Ideally, the sample should also be sent to the laboratory to get an actual value of fPLI to help with treatment and monitoring.

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. This article discusses causes, signs, diagnosis, treatment, and prognosis for cats with this condition.

Panniculitis is a localized inflammation of the tissues under the skin, causing a firm swelling (nodule) that may ulcerate and drain fluid. It is a common problem in cats and is less common in dogs. There are several causes of panniculitis, but in younger animals with a single lump, the cause is often blunt trauma and, in cats, it is often caused by bite wounds from fighting. An accurate diagnosis relies on the microscopic examination of tissue and the most common treatment is the surgical removal of the lump(s).

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.

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.

Pets may have visible or hidden disabilities that require some adjustments to their care or lifestyle to maximize their quality of life. With some support, these pets can have a fairly normal life and be just as loving as any other pet.

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.

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.
