You can find it here.

You will need to use this calculator at least once a week to account for weight gain and keep your dosage accurate.


Visit our STEP 1 page for more information about how this treatment works, how to administer it, how to adjust the dosage and other important information regarding FIP in cats.


Recommendation note:
We know how important it is to start treatment as soon as possible. That is why we keep our costs low and ensure that every cat, even those who appeared to be lost in FIP darkness for all eternity, can have a better chance to be saved!
Treatment is easier and more effective when started early. Delaying treatment can be disastrous, as later stages of FIP require double the dosage and exponentially reduce your cat's chance of survival.


We love cats and prioritize their health and happiness:

While other merchants may make bold claims such as "The cure is here" or "99% chance of being cured," we choose to present a realistic picture without compromising your trust. We understand that every cat is unique, and we cannot guarantee a 100% success rate. Although GS treatment has not yet met the legal requirements to be labeled as a cure, we are confident that it is one of the best chances your cat has to fight FIP.
(You can explore numerous case studies and positive testimonials regarding GS treatment starting from 2019.)


Please take the time to read our disclosures carefully so that you can make an informed decision about your cat's treatment. If you find yourself in disagreement for any reason, we respect your choice; please discuss alternative treatment options with your veterinarian.



Please contact us if you have any questions. Your pet is in our prayers!  


  • NO GUARANTEE of cure is made. By purchasing, you agree that you understand that the treatment is experimental and may or may not result in the successful treatment of the condition and that you will not consider FIPCAT viable if your pet dies or shows any side effects.  Please read all other disclaimers. If you disagree, consult your veterinarian about other options.
