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. In cats, it is often caused by bite wounds from fighting. This handout discusses causes, signs, and treatment of this condition.

Pantoprazole is a proton pump inhibitor (stomach acid reducer) used to treat stomach ulcers in cats, dogs, and other animals. It has also been used to treat esophagitis and gastric reflux. This medication is used off-label in veterinary medicine.

Papillomas are benign, sometimes multiple, tumors caused by viruses. They are commonly known as warts. The virus is transmitted through direct contact from an infected pet or the pet’s environment (e.g., toys, food bowls, or bedding) and gain access to the body when the skin becomes softened by moisture, through cuts and abrasions, or with the assistance of insects. Pets with immature immune systems such as young dogs and puppies, and those that are immune compromised, are more prone to developing papilloma tumors. The tumors often disappear within 1-2 months because the animal slowly develops an immunity to them. However, sometimes they persist, and surgical removal is necessary.

Parathyroid tumors are uncommon in dogs and cats. Benign adenomas occur more often than malignant tumors. Keeshonds appear to have a genetic predisposition to developing parathyroid tumors, but no breed or genetic relationship has been established in cats. Pets may exhibit signs of lethargy, little or no appetite, vomiting, and muscle twitching. Diagnosis is confirmed with PTH testing and ultrasound of the neck region after hypercalcemia is observed on bloodwork. Surgery to remove the affected gland(s) is the typical treatment, but ultrasound-guided ablation may be pursued. Careful monitoring of calcium levels post-surgery is important, as some pets may develop transient hypocalcemia and require calcium supplementation. Prognosis is excellent, and the metastatic rate for these tumors is extremely low.

Paromomycin (Gabbrovet®, Parofor®) is an aminoglycoside antibiotic used to treat intestinal parasites in dogs, cats, cattle, sheep, goats, pigs, amphibians and reptiles. In dogs, paromomycin is also used topically to treat cutaneous leishmaniasis.

Paroxetine (brand names: Paxil®, Brisdelle®) is a selective serotonin reuptake inhibitor (SSRI) antidepressant used to treat canine aggression, anxiety, and stereotypic/obsessive compulsive behaviors. In cats, it has been used to treat aggression, urine marking, and other behavior problems.

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.

Penetrating wounds can look minor on the surface but may cause severe injury below the skin. A thorough assessment requires sedation or anesthesia and surgery may be required to address the extent of the injury. This handout outlines first aid steps a pet owner can take while transporting their injured pet to the veterinary hospital.

Penicillamine is used to treat copper-storage disease and copper-related liver disease in cats and dogs, subclinical hepatitis in Dobermans, and to treat cystine bladder stones in dogs. It has also been used as an antidote and chelating agent in the treatment of lead or mercury poisoning in birds, cats, and dogs.
