Feline Immunodeficiency Virus (FIV), a slow-acting virus, is not the catastrophe it was once made out to be. While FIV diagnosis requires extra support and care, it is a manageable condition. To provide the best care for an FIV+ cat, understand what is actually happening inside their body. FIV targets the immune system itself, damaging and destroying white blood cells, causing their white blood cell numbers to drop. There are three stages to the disease, the Acute Phase, the Asymptomatic phase, where the virus is present but dormant, many cats will stay for their entire lives. The Progressive Phase is when chronic infections become more common and difficult to treat, particularly in the mouth, skin, or respiratory tract. The Three Stages of FIV in Cats can help manage expectations, your vet visits, and the best options for supportive care at home.
