Gini,

Thanks for your suggestion. That's exactly what I did.

After trying to sleep for 2 1/2 hours (everytime I started drifting off, Casey would gasp for air), I got up and here I am.

I looked into FIP. The reason being, when MooShoo was 12 weeks old, he tested positive for FIP, which means he was exposed to the virus, as were the rest of my cats.

According to Cornell University, FIP is a very frustrating disease because it consists of 7 coronaviruses. The only way to truly detect it is by doing a post-mortem necropsy (autopsy), by testing the tissue of an infected cat.

Some of the symptoms of FIP are so similar to what I've seen in Casey (diarrhea over time, sneezing, watery eyes, lethargy,antibiotics failure to take care of an infection, loss of appetite), that I'm very suspicious THAT is what is happening here.

I am absolutely devastated at this point because I feel deep down inside he IS suffering and I don't want that.

The questions running through my mind are "Do I keep him on the medicine another 10 days to see if he does any better???" (even after all these weeks of medication and poor results). "Do I take him off all medicines to see if he improves???" "Do I make the ultimate decision that enough is enough and have him put down so that he doesn't suffer, yet always wondering if I did the right thing???"

I am so confused right now. I need answers and there don't seem to be any.
