Hello! If you’d like, I can take a look at your cats’ medical history and the test results that led to the FIP diagnosis.

The reason I’m asking is that FIP itself is generally not considered directly contagious. While cats living together can be exposed to feline coronavirus, it would still be relatively unusual for two cats in the same household to develop FIP at the same time.

Because FIP is a serious diagnosis, it’s very important to be as certain as possible before committing to treatment. A second opinion may also help avoid unnecessary expenses, especially since GS-441524 is not a cheap medication and treatment can last anywhere from several weeks to around 12 weeks, depending on the protocol and the individual case.

If you’d like a second opinion, feel free to send me a private message with their medical records, blood tests, and any other relevant results. I’ll do my best to help you make sense of everything.
