  I've had two cats die from FIP. Rather than breathing problems, it expressed itself as a wasting disease. (non-effusive FIP) The cats (wanted to) ate practically 24/7, their hunger being unable to be satisfied. Terrible diarrhea, leading to liver failure and death over the course of a week from first apparent symptoms. One of the cats became so jaundiced that her eyes and skin were almost a florescent yellow before her death. The other experienced such radical muscle atrophy in his hinds after just two weeks of symptoms that he became immobile. He shortly after suffered a stroke or similar such anomaly and died a few days after becoming immobile. He still had a voracious appetite -- even after becoming immobile. It's a brutal and devastating disease for felines. It's also easily transmissible between neighborhood cats. It's a horrible diagnosis to hear from a vet -- it harbors very little hope for the patient. The only silver lining is the usual quickness of the death. I'm sorry that you and your pets had to go through it.
