Primary liver tumors in dogs and cats are rare. There are 4 types: hepatocellular tumors, bile duct tumors, neuroendocrine tumors, and sarcomas. These cancers can be massive, nodular, or diffuse in form. In dogs, most liver tumors are malignant, while in cats, most are benign. The signs of liver tumors range from being asymptomatic to having inappetence, fever, lethargy, and weight loss; and less commonly, nausea, vomiting and diarrhea; increased drinking and urination; and jaundice. Occasionally there are neurological signs, such as seizures. With tumor rupture and intrabdominal bleeding there may be weakness, collapse, and difficulty breathing. The diagnosis is based on history, clinical signs, exam findings, diagnostic imaging, and FNA or liver biopsy. A biopsy is best for a definitive diagnosis. Surgery is the treatment of choice for most primary liver tumors followed by chemotherapy. Chemoembolization is a newer treatment.

Lories and Lorikeets are small to medium size, energetic parrots. They come from southeastern Asia, Papua New Guinea, Australia, and Polynesia.

Grief is the normal and natural response to the loss of someone or something. It is a full body experience that includes physical, emotional, cognitive, social, and spiritual responses. The best way to manage your grief is to be reassured that these reactions are normal and to let them run their natural course. Grieving takes time. Usually it gradually lessens in intensity over time, but if it doesn’t, then professional counseling may help.

The peach-faced lovebird is the largest and most commonly kept of the nine species of lovebirds. Lovebirds are incredibly inquisitive, playful, and possess a delightful, spirited sassiness. Although not generally very destructive, they do enjoy chewing. Young, single love birds bond closely with their owners and can be a wonderful, affectionate, and interactive family pet. A pair of lovebirds often bonds more strongly to each other even if they are the same sex. Young birds may be easier to tame and train than older, wild-caught, or colony- or parent-raised birds. After bringing your new bird home, you should have it examined by a veterinarian familiar with birds to help ensure that it is healthy. Like all other pet birds, lovebirds require annual, routine veterinary health check-ups.

Lung flukes in North America are parasites called Paragonimus kellicotti that infect the lungs of cats after they have eaten an infected crayfish or rodents that have eaten infected crayfish. Eggs are then released by the parasite into the cat’s sputum to be coughed out or swallowed and released in the feces to continue the life cycle. Lung flukes can be found anywhere in North America but more commonly around the Mississippi River and Great Lakes. Infected cats can be symptom-free or may develop cough with sometimes bloody mucus, pneumonia, pneumothorax, lethargy and weakness. Diagnosis can include locating eggs of the parasite from feces or mucus from the lungs. X-rays can also reveal cysts in the lungs caused by the parasite. Treatment requires one of 2 commonly used anti-parasitic medications: Praziquantel or Fenbendazole. Although zoonotic, these parasites won’t transmit directly from cats to humans.

Lung tumors are considered rare in cats and dogs. Many pets may not show symptoms at first, and a tumor may be found coincidentally. Depending on the type and stage of cancer, treatment may be possible; otherwise, symptomatic supportive care may be an alternative option.

In North America, many parasitic lungworms infect cats. Cats can become infected by swallowing infective stages of parasitic lungworm. The exact means of becoming infected varies according to the life cycle of the particular parasite. Signs can include coughing, heavy breathing, wheezing, sneezing, poor appetite or anorexia, weight loss, fever, enlarged lymph nodes, and ocular or nasal discharge, and may be more prominent in kittens due to their immature immune systems. Although the success rate of treatment depends on the severity of symptoms and the number of parasites present, the prognosis for recovery is generally good.

There are many species of lungworm that can cause respiratory problems in dogs. Infection is acquired through either: ingestion of an intermediate host such as snails or slugs, ingestion of animals that have been infected by eating these animals or depending on the species, from an infected dog by contact with saliva, nasal discharge, or contaminated food and water bowls. Lungworms can be found throughout North America and the world with certain species seen in certain areas. Clincal signs can range from asymptomatic to tachypnea, coughing, sneezing, wheezing, respiratory distress or exercise intolerance. The degree of clinical signs is usually proportional to the strength of the dog’s immune system. Diagnosis involves history, physical exam, x-rays and organism identification through either baermann fecal examination or BAL/bronchoscopy. Treatment involves use of specific antiparasitic drugs for various lengths of time depending on type and severity of infection. Prognosis is good but re-infection can occur.
