I am so sorry about Chili. I want to tell you about my tuxedo cat, but don't want to unnecessarily alarm at the same time. The only common thread our cats share is the high white blood cell count, which became way out of sight with my cat. The first thing I noticed was that there were no stools in the litter box. That led me to observe that she wasn't eating. The first vet diagnosed some unknown infection and sent me home with antibiotics and something else - I can't even remember. After no improvement, I took her to the second vet, who was just positive that tests would confirm his suspicions of kidney failure. Well, it wasn't that so he sent me home with the same meds. No improvement. The third vet diagnosed her with FIP, the effusive kind, which was obvious with her distended abdominal area. By this time it was so bad that there was pressure on her diaphragm with made breathing difficult. He wanted to treat her, but cautioned me that very few cats respond to treatment, and those that do only survive less than a year. We elected to have her put down because she was in her late teens. It is a horrible disease and difficult to diagnose. One point of telling you this is that sometimes it takes more than one vet to figure out what is going on.
