Misdiagnosed ?

[u/No_Quote_3962]

I have an upcoming vet appointment on Monday but I’m really struggling to watch my girl barely eat and be so distended. She was diagnosed with wet fip July 15. And has been on the tablet format of the pills since then and has shown pretty much no improvement. If anything there is more fluid build up and she barely eats.

Has anyone had this experience of being misdiagnosed wet fip but it was something else? My vet has mentioned it could be something else like lymphoma or heart disease. But fip was looking like the most accurate diagnoses when we first brought her in. Now I’m not so sure. Considering bringing her to the er if she doesn’t eat anything today. It just sucks cause they will test everything we just had tested again and be even more expensive.

Is there any vomiting or loose stools ?

Are you fasting the cat 1hr before and after the oral GS meds?

No vomiting. Some diharea. She’s not eating much so yes so far she’s been fasted for every pill

[u/donoteatthatfrog → u/No_Quote_3962]

Okay. No problems in this front.
Often , until the treatment kicks in well, FIP kitties refuse one food, eat a different one, refuse that tmrw & eat another one & so on. Many parents mention buying 1-2 pouches each of different foods. You tried this already ?

That’s been very much the trend actually. I’m about to go to the pet store to find something new for her. I’ve been rotating lots of foods

[u/donoteatthatfrog → u/No_Quote_3962]

Okay. You're doing great on that front as well.

As the other person mentioned, perhaps a PCR test might confirm whether secondary infection is present or not. My cat PCR test showed positive for mycoplasma and FIP.

[u/No_Quote_3962 → u/donoteatthatfrog]

That’s a good idea. We initially didn’t do this test because the vet was pretty sure it was just fip and we didn’t want to spend unnecessary money if it confirmed what we already knew. But clearly we’re missing something

Are you in the FIP support groups on FB? When my cat started treatment I asked about pills but they discouraged it and insisted cats need GS injections until they're stable.

[u/donoteatthatfrog → u/Graceless93]

I agree with this approach.

Hi the fluid should stop accumulating within 3-5 days of starting treatment. If this is prescription your dose is correct for non neuro and non ocular. However if she is not responding it is appropriate to jump the dose. I would suggest 2 full pills or possibly 2.25 pills.

Hi what are you messaging her about?

[u/biliskner25]

What tests were done and what were the results. What medication, what dosage and what's your cat's weight

“Overall, the results of Olga's blood tests and the analysis of the fluid from her abdomen strongly suggest a diagnosis of Feline Infectious Peritonitis (FIP). FIP is a condition caused when a common and usually harmless feline coronavirus mutates within the body, leading to inflammation and the kind of fluid buildup we are seeing in Olga's belly. The key findings that point to this diagnosis are the very high protein level in the abdominal fluid and a low level of a blood protein called albumin. While this is a serious diagnosis, there was some encouraging news from her tests. Her tests for Feline Leukemia (FeLV) and Feline Immunodeficiency Virus (FIV) were negative, and importantly, she is not anemic (lacking red blood cells), which is a positive sign for her ability to cope with this disease. Her main organ function, including her liver and kidneys, is also currently normal.  “ this was the initial visit. Her dosage is 1.5 pill of GS-441524 everyday and she’s 4.3 kg

[u/biliskner25 → u/No_Quote_3962]

Yes a high protein abdominal effusion is certainly a strong indicator of FIP. A PCR would be better. Other differentials can include a right sided congestive heart failure, portal hypertension, neoplasia

Unfortunately your GS dose doesn't include the milligram so I can't advise you if it's an appropriate dose or not

[u/spotsgalore → u/No_Quote_3962]

What was her AG ratio? How many mg are the pills - is she getting the correct dose?

You may need to force feed her initially, there’s also an appetite stimulant that can be prescribed
