Guinea pigs live, on average, 5-6 years; although some can live to 8-10 years of age. Their teeth grow continuously, throughout life, and it is critical that they eat grass hay, such as Timothy hay, every day to help them wear down their teeth as they grow. Young guinea pigs display a unique behavior called popcorning when they are happy, in which they jump straight up in the air and let out squeals of delight. Guinea pigs reach sexual maturity at around 3-4 months of age; therefore, if young males and females are housed together, they should be separated by this age, otherwise they are likely to breed. The average gestation period for guinea pigs is 63 days. If gestation continues over 70 days, the guinea pig should be seen immediately by a veterinarian, and it is likely that the entire litter will be stillborn.

Pacheco's disease is caused by an avian herpesvirus. It is often a fatal disease, but treatment with an anti-herpes medication may be life-saving if used at first presentation. This disease is seen less often in today's pet bird population since most parrots are domestically raised and not imported.

Most cats instinctively hide their pain as a survival mechanism which can make detecting pain in cats a challenge. Although the signs may be subtle, careful observation of a cat’s everyday behaviors will often reveal pain when it is present. These signs may include changes in behavior, mobility, elimination, and grooming habits. Common pain medications include NSAIDs and opioids. Your veterinarian will choose the appropriate drugs based on your cat's specific needs.

Many dogs will instinctively hide their pain as a survival mechanism which in the past, led well-meaning experts to presume that dogs did not feel pain the same way humans do. Although the signs may be subtle, careful observation of a dog’s everyday behaviors will often reveal pain when it is present. These signs may include changes in behavior, mobility, and appetite. Common pain medications include NSAIDs, opioids, and other therapeutics. Your veterinarian will choose the appropriate drugs based on your dog’s specific needs.

Primary pancreatic tumors are rare in dogs and cats. Exocrine tumors include adenomas and adenocarcinomas, and endocrine tumors include insulinomas, gastrinomas, and glucagonomas. Insulinomas are the most common type of pancreatic tumor, followed by adenocarcinomas. Both tumors are more common in dogs than cats. Large breed dogs and Siamese cats may be predisposed. Insulinomas are usually diagnosed with the finding of hypoglycemia with normal to high insulin on bloodwork and concomitant clinical signs. Adenocarcinomas typically go undetected until the clinical signs of metastasis are evident. For both tumors, diagnostic imaging and exploratory surgery with tumor removal (or biopsy) and histopathology are needed for a definitive diagnosis. Insulinomas can be treated with surgery and chemotherapy. Surgery is possible with adenocarcinomas, but as the cancer is more diffuse and has usually metastasized by the time of diagnosis, the prognosis is poorer. Chemotherapy and radiation therapy are ineffective in the treatment of adenocarcinomas. Given the high rate of metastasis with these tumors, staging is recommended prior to surgery.

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.

The pancreas is a vital organ that produces enzymes to assist in food digestion and hormones such as insulin, which regulates blood sugar or glucose metabolism. Pancreatitis is inflammation of the pancreas. Common clinical signs include decreased appetite, nausea, vomiting, lethargy, diarrhea, and abdominal pain. Diagnosis is generally made with laboratory testing and/or abdominal ultrasound. Successful pancreatitis management will depend on early diagnosis and prompt medical therapy. The prognosis depends on the severity of the disease and the response to initial 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. A version of the cPLI test can now be used in-clinic (SNAP fPL© from IDEXX). Ideally, the sample should also be sent to the laboratory to get an actual value of cPLI to help with treatment and monitoring.

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).
