MolnuFIP™ delivers pure EIDD-1931, the active antiviral metabolite of molnupiravir, in a formulation designed exclusively for feline physiology. By using EIDD-1931 directly—rather than modifying human molnupiravir capsules—MolnuFIP™ provides a more precise, consistent, and veterinary-appropriate approach to FIP care.
Purpose-Built Feline Formulation
Each MolnuFIP™ capsule contains 15 mg of EIDD-1931, equivalent in activity to approximately 66 mg of molnupiravir (EIDD-2801).
This formulation is optimized for:
Feline metabolic rate
Gastrointestinal absorption profile
Reliable dose–response performance
The result is accurate, predictable antiviral activity with reduced variability compared to human-intended products.
Proven Antiviral Potency
Published research demonstrates that:
EIDD-1931 exhibits up to 10× greater in-vitro antiviral potency compared with molnupiravir (EIDD-2801).
EIDD-1931 demonstrates 7.3× higher potency than GS-441524 under similar test conditions.
This potency advantage enables therapeutic efficacy at lower milligram doses, supporting improved tolerability and rapid clinical response.

Reviews
My cat was diagnosed with FIP - she was having high fever, and stomach filled with fluid, she had lost her appetite, i started giving her Molnupiravir 15 mg x 2 times a day , it was big capsule so i couldnt give to the cat so i opened the capsule and put it in the meao treat and gave it to her . with in a week the fluid build up stopped and she started eating regular food . now she is all ok but still iam going to give it for few days .
The pills are large and high quantity of powder, so it has to be mixed with food and not given separately, but so far results are good and it is economical too.
