Research overview: calicivirus and caudal stomatitis in cats

Feline calicivirus has been associated with caudal stomatitis, inflammation in the back of the mouth that is a hallmark of chronic gingivostomatitis, leading researchers to investigate the virus's role in driving or perpetuating the aberrant immune response underlying this painful condition. Many affected cats persistently carry calicivirus. This overview synthesizes the virology and dental literature rather than one citation, describing the proposed link between persistent calicivirus infection and oral inflammation, why the virus's strain diversity and immune interactions complicate the picture, and how this association informs both understanding and management of stomatitis. It matters because clarifying the viral contribution to gingivostomatitis could improve treatment of a disease that causes severe suffering and often resists conventional therapy, making the calicivirus connection an important avenue of feline oral-disease research.
