![]() There are two major forms of FIP, an effusive, or “wet” form and a noneffusive, or “dry” form. Only a small percentage of cats that are exposed to the FeCV develop FIP, and this can occur weeks, months, or even years after initial exposure to FeCV. In most cases, these mild signs are self-limiting. ![]() Some cats may show mild upper respiratory symptoms such as sneezing, watery eyes, and nasal discharge, while others may experience mild gastrointestinal signs such as diarrhea. To our knowledge, coronaviruses cannot be passed from infected cats to humans.Ĭats that have been initially exposed to FeCV usually show no obvious symptoms. Once a cat develops clinical FIP, the disease is usually progressive and almost always fatal without therapy that has recently become available, but that has yet to be approved to treat FIP in cats by the Food and Drug Administration (FDA) (see below). It is this interaction between the body’s own immune system and the virus that is responsible for the development of FIP. An intense inflammatory reaction to FIPV occurs around vessels in the tissues where these infected cells locate, often in the abdomen, kidney, or brain. When this occurs, the virus is referred to as the FIPV. In approximately 10 percent of cats infected with FeCV, one or more mutations of the virus can alter its biological behavior, resulting in white blood cells becoming infected with virus and spreading it throughout the cat’s body. FeCV-infected cats usually mount an immune response through which antibodies against the virus are produced within 7-10 days of infection. Cats infected with FeCV usually do not show any symptoms during the initial viral infection, but may occasionally experience brief bouts of diarrhea and/or mild upper respiratory signs from which they recover spontaneously. These are referred to as feline enteric coronavirus (FeCV). ![]() ![]() Most strains of feline coronavirus are found in the gastrointestinal tract and do not cause significant disease.
