As of February 2019, yes!  Thousands of cats have used GS441 from China and have been clinically cured of feline infectious peritonitis.  GS441 has effectively cured wet FIP, dry FIP, ocular and neurological FIP.  GS441 comes in both oral and injectable form. The treatment protocol calls for 12 weeks of daily administration of the drug. Most cats see significant improvement of physical symptoms within the first 1-3 days, but require the full course of treatment to fully eradicate the virus.

No.  What is sometimes called (incorrectly) and “FIP test” is actually an FCoV titer test.  This test can show if the cat has been exposed to the coronavirus, but is in NO WAY indicative of FIP. 

A proper FIP diagnosis requires a combination of diagnostics, including but not limited to: physical exam, complete blood count, RT-PCR of effusion (wet FIP), and  PCR (RT-qPCR) on fine-needle aspirates (dry FIP). 

No.  The coronavirus is highly contagious and most cats will be exposed to it at some point during their life.  FCoV is shed through feces, so cats who share a litter box or groom one another are exposed to the benign form of the virus.  Cats who have a healthy immune system will pass the coronavirus with little to no issue other than a bout of diarrhea and/or cold-like symptoms.

Cats who have a weakened or not fully developed immune system may not be able to pass the coronavirus, and the virus mutates into FIP.  Once mutated into FIP, the virus is no longer contagious. 

There is believed to be a genetic component with FIP, so biological litter mates may share the same genetic predisposition that allows FCoV to mutate.  A family history of FIP does unfortunately increase the likelihood that siblings will develop FIP.    

The recommended length of treatment is 12 weeks. However, the actual treatment length may depend on many factors such as how quickly your cat responds to the treatment,  the stage of the FIP infection when you began the treatment, and your personal financial situation. 

Yes, GS is an antiviral treatment, and can be used with other medications to improve the overall health of your cat.  However, it is not recommended to use Lysine IS with GS or antibiotics called Fluroquinolones along with GS because they can be harmful to the nervous system of cats with FIP.

Each treatment option has its pros and cons. Both treatment options are effective against feline infectious peritonitis (FIP) infections.  Vials are precise and more controllable.  The effects are immediate.  We recommend starting all feline infectious peritonitis (FIP) treatments with vials.  Oral tablets are easier to administer, cause no pain, and can be done easily at home.  However, GS-441524 will take longer to travel to the bloodstream because it first has to go through the digestive system.  It is also impossible to know how much of the GS-441524 is absorbed by the body to combat FIPV.   We recommend starting oral capsules treatment only after your cat’s condition is stable. Feline infectious peritonitis virus often damages digestive organs such as the stomach, intestines, kidneys and liver as it spreads throughout the body. Damaged organs reduce digestive functions and will cause poor absorption of GS-441524 into the bloodstream.  When oral capsules are given too early in the treatment, it may cause prolonged treatment or higher chances of relapse in the future.
