Polyprenyl Immunostimulant™ and your cat.
Polyprenyl Immunostimulant™ is a unique veterinary biologic USDA-approved for the treatment of feline viral rhinotracheitis (FVR, FRV, FHV-1), a common and ubiquitous upper respiratory infection (URI). Also referred to as PI or PPI, Polyprenyl Immunostimulant™ was designed and developed specifically for cats. PI works by upregulating innate immunity and directing the cellular immune response.
Following research conducted by Dr. Al Legendre of the University of Tennessee-Kentucky, PI is often used by veterinarians to treat cats with FIP (Feline Infectious Peritonitis). It is available through veterinarians.
