At the RVC we have started treating cats affected by feline infectious peritonitis (FIP) with two newly available anti-viral drugs: remdesivir and GS-441524.

Until recently FIP was sadly an invariably fatal disease, with very few treatment options. Due to the Covid-19 outbreak, novel anti-viral drugs have become available not just for human but also for veterinary use. The first cat to be treated with remdesivir at the RVC was Merlin in August 2021. Since that time, we have been able to offer this treatment to many other cats with FIP with good outcome and our experience with remdesivr and GS-441524 for treating FIP is rapidly evolving.

Further information for owners and referring veterinary surgeons regarding diagnosis of FIP, treatment options and expected outcomes can be found using the following links:
