Glossary Term: Feline Leukemia

Feline Leukemia (FeLV) is a viral disease that affects cats, and is caused by the feline leukemia virus. It is one of the most common causes of death in cats. The virus can be spread through direct contact with an infected cat, through shared food and water bowls, or through the air. Symptoms of FeLV can vary and can include fever, weight loss, lethargy, poor appetite, enlarged lymph nodes, pale gums, and diarrhea. In some cases, cats may also develop anemia or respiratory problems.

If left untreated, FeLV can lead to a variety of health problems such as anemia, cancer, and immunodeficiency. In immunodeficiency, the cat’s immune system becomes weakened, making them more prone to infection and disease. FeLV can also cause a decrease in fertility and can be passed from a mother to her unborn kittens.

Fortunately, there is a vaccine available for FeLV that can help protect cats from becoming infected. It is recommended that all cats receive the vaccine, especially if they are at risk of coming into contact with an infected cat. Additionally, it is important to keep cats from coming into contact with other cats that may be infected, through regular health check-ups and by avoiding contact with cats that may be sick or have unknown health histories. It is also important to practice good hygiene when handling cats, and to keep litter boxes and food bowls clean.
