Welcome to the Essential FIP Survivor Guide website.
This guide focuses on the treatment of the non-effusive (dry form) of Feline Infectious Peritonis (FIP), a fatal disease with currently no cure or vaccine. The treatment discussed in the guide is an off-label use of a veterinary biologic called Polyprenyl Immunostimulant (PI). We currently have over eighty cats diagnosed with FIP who are surviving, some for years, with great quality of life and no clinical signs.
