For cat owners across the United States, Feline Infectious Peritonitis (FIP) remains one of the most devastating and confusing diagnoses.While GS-441524 has proven to be highly effective, access challenges, treatment costs, and rising FIP cases across the country have led many pet owners and rescuers to seek safer, more affordable antiviral alternatives.
One of the most promising options emerging from recent scientific research is Molnupiravir—specifically its active antiviral form EIDD-1931, branded as MolnuFIP™.Unlike human Molnupiravir (EIDD-2801), which was originally created for COVID-19 patients, MolnuFIP™ is formulated specifically for cats and optimized for feline metabolism.

This is critical because cats process antiviral drugs differently from humans, and using human medications off-label can be risky or ineffective.
What Is EIDD-1931 (MolnuFIP™)?
EIDD-1931 is the active metabolite of Molnupiravir—the compound responsible for stopping the FIP virus from replicating.
Human Molnupiravir (EIDD-2801):
is a prodrug,
requires conversion in the liver,
and does not activate efficiently in cats.
MolnuFIP™ solves this problem by delivering ready-to-act EIDD-1931, resulting in:
faster antiviral activity
higher potency
more consistent clinical response
Scientific studies show EIDD-1931 to be 4.4 times more potent than human Molnupiravir, with real-world success rates of about 97% in wet and dry FIP cases.
Key Advantages of EIDD-1931 (MolnuFIP™)
✔ Formulated specifically for cats
✔ Immediate antiviral effect (no metabolic conversion required)
✔ Softgel capsules—easy to administer
✔ No reported cases of viral resistance
✔ Most cats show improvement within 5–7 days
These benefits offer U.S. pet owners a safer, more predictable treatment path than using human medication not designed for feline physiology.
