Feline leukemia, also known as feline leukemia virus (FeLV), is a viral disease that affects cats worldwide. It is a significant cause of illness and death in cats, particularly those that are infected at a young age or have weakened immune systems. The symptoms of feline leukemia can vary widely, making it challenging for cat owners to recognize the disease in its early stages. In this article, we will delve into the common symptoms of feline leukemia, its causes, diagnosis, and treatment options, providing cat owners with the necessary knowledge to protect their feline friends.
The feline leukemia virus is highly contagious and can be transmitted through direct contact with an infected cat's saliva, blood, or other bodily fluids. Kittens can also contract the virus from their mother during birth or nursing. Once a cat is infected, the virus attacks the immune system, making it difficult for the cat to fight off infections and diseases. The symptoms of feline leukemia can be divided into three stages: acute, subacute, and chronic.
Key Points
- Feline leukemia is a viral disease that affects cats worldwide, causing a range of symptoms from mild to severe.
- The disease is highly contagious and can be transmitted through direct contact with an infected cat's saliva, blood, or other bodily fluids.
- Kittens can contract the virus from their mother during birth or nursing, making them more susceptible to the disease.
- The symptoms of feline leukemia can be divided into three stages: acute, subacute, and chronic, each with distinct characteristics.
- Diagnosis of feline leukemia typically involves a combination of physical examination, laboratory tests, and imaging studies.

The acute stage of feline leukemia is characterized by mild symptoms, such as fever, lethargy, and loss of appetite. Some cats may also experience vomiting, diarrhea, or respiratory problems. In this stage, the virus is actively replicating, and the cat’s immune system is trying to fight it off. If the cat’s immune system is unable to clear the virus, the disease progresses to the subacute stage.
In the subacute stage, the symptoms of feline leukemia become more pronounced. Cats may experience weight loss, pale gums, and anemia. They may also develop secondary infections, such as pneumonia or skin infections, due to their weakened immune system. Some cats may also exhibit neurological symptoms, such as seizures or tremors. The subacute stage can last for several weeks or months, during which time the cat's condition may deteriorate rapidly.

The chronic stage of feline leukemia is the most severe and debilitating stage of the disease. Cats in this stage may experience severe weight loss, muscle wasting, and skin problems. They may also develop opportunistic infections, such as toxoplasmosis or cryptococcosis, which can be life-threatening. In addition, cats in the chronic stage may exhibit behavioral changes, such as aggression or withdrawal, due to the progression of the disease.
| Stage of Feline Leukemia | Symptoms |
|---|---|
| Acute | Fever, lethargy, loss of appetite, vomiting, diarrhea, respiratory problems |
| Subacute | Weight loss, pale gums, anemia, secondary infections, neurological symptoms |
| Chronic | Severe weight loss, muscle wasting, skin problems, opportunistic infections, behavioral changes |
Diagnosis and Treatment of Feline Leukemia
Diagnosing feline leukemia typically involves a combination of physical examination, laboratory tests, and imaging studies. A complete blood count (CBC) and blood chemistry profile can help identify abnormalities in the cat’s blood, such as anemia or low platelet count. A polymerase chain reaction (PCR) test or enzyme-linked immunosorbent assay (ELISA) can detect the presence of the feline leukemia virus in the cat’s blood or saliva.
Treatment of feline leukemia depends on the stage of the disease and the cat's overall health. In the acute stage, treatment may involve supportive care, such as fluid therapy and antibiotics, to manage secondary infections. In the subacute and chronic stages, treatment may involve more aggressive measures, such as chemotherapy or immunomodulatory therapy, to slow the progression of the disease. Unfortunately, there is no cure for feline leukemia, and treatment is often focused on managing the symptoms and improving the cat's quality of life.
Prevention of Feline Leukemia
Preventing feline leukemia is crucial to reducing the risk of transmission and protecting cats from the disease. Cat owners can take several measures to prevent feline leukemia, including vaccinating their cats against the disease, preventing exposure to infected cats, and practicing good hygiene, such as washing hands and cleaning food and water bowls regularly. Additionally, cat owners should ensure that their cats are spayed or neutered to reduce the risk of transmission through breeding.
