Feline Leukemia Virus (FeLV) is a highly contagious retrovirus that affects cats, and the abbreviation FELV stands for Feline Leukemia Virus. It is one of the most common infectious diseases observed in domestic cats worldwide. FeLV can cause a wide range of symptoms and health issues, including anemia, suppression of the immune system, infection, and the development of various types of cancers.
FeLV is primarily transmitted through close contact between infected and non-infected cats, such as through mutual grooming, sharing food and water dishes, and biting. Kittens can also acquire the virus from infected mothers during birth or through drinking infected milk. Once a cat is infected, the virus can be present in various body fluids, including saliva, urine, feces, and nasal secretions, making it highly contagious.
The severity of the disease can vary among infected cats, and some may be able to fight off the virus and serve as carriers without developing symptoms or becoming severely immunocompromised. However, other cats may experience chronic illnesses, progressive immune system suppression, and ultimately succumb to the disease.
Preventing FeLV infection is crucial, and vaccination against the virus is available and recommended for all cats, especially those that have outdoor access or are exposed to potentially infected cats. Regular veterinary check-ups and testing can help detect and manage the disease early on. Additionally, keeping infected cats isolated from uninfected ones and maintaining clean living environments can help minimize the spread of the virus.
