In summer of 2009, an exciting paper appeared by Prof. Al Legendre of Tennessee Veterinary School in the Journal of Feline Medicine and Surgery reporting cure of 3 cases of non-effusive FIP using
Polyprenyl Immunostimulant from Sass & Sass.
Unfortunately,
Polyprenyl Immunostimulant does not work on effusive (wet) FIP cases.
2009 Effect of
Polyprenyl Immunostimulant on the survival times of three cats with the dry form of feline infectious peritonitis.
I remain skeptical that
polyprenyl immunostimulant is of any value to your cat.
Dr. Al Legendre, professor in the department of small - animal clinical sciences at the University of Tennessee College of Veterinary Medicine, Knoxville, is working on how one drug,
Polyprenyl Immunostimulant, seems to be helping some cats with FIP.
