It's all fluid, but they couldn't get a sample?! Doesn't that seem weird to you guys? Did they not have an ultrasound machine in the clinic? They should be able to easily find a fluid pocket using ultrasound. Take her to a different vet tomorrow if you can (one with a decent hospital and the proper facilities/technology)! I assume they did OTHER testing to come up with this FIP diagnosis? Please ask them what her feline coronavirus (FCoV) titer was. Ask them what her albumin:globulin (A:G) ratio was in her blood plasma. In FIP, AGP levels are usually greater than 1500 mg/ml. In normal cats, it’s up to 500 mg/ml. What is her Alpha one acid glycoprotein (AGP) level? In FIP, AGP levels are usually greater than 1500 mg/ml. In normal cats, it’s up to 500 mg/ml. Is she jaundiced? Does she have the typical eye symptoms associated with FIP? Does she have neurological signs, ataxia (wobbly and falling over when walking), head tremors, seizures, or are her eyes may dart from side to side?
Once you find a better vet (one able to stick a needle in something the size of a grapefruit), take this webpage, print it off, and demand they run these tests: http://www.dr-addie.com/WhatIsFIP.htm#Wet%20or%20effusive%20FIP Phaewryn
