I'm so sorry to hear this. My cat Ziggy Stardust was diagnosed with a minor case of this several weeks ago but it's still inconclusive if she ever had this or not. She just stopped eating and then if she did eat she'd throw it back up again. I had to hospitalize her for about 24 hours and luckily when I brought her home she started eating on her own again. At first she didn't eat as much as before but now she's totally back to normal and doing great. She had 3 very stressful episodes before this happended and my vet said that stress can cause this.

Has she had an ultrasound done yet? Has she had bloodwork done? Even if the bloodwork results are normal it still doesn't rule this out. Have you been giving her sub-q fluids or liquid pepcid? This is what I was sent home with for Ziggy as well as appetite stimulant pills. Later she received a vitamin B-12 shot instead to help stimulate her appetite because the pills were upsetting her stomach. I'm supposed to continue giving these to her once a week until I'm out of it. She was also on liquid antibiotics for quite a while too. I sure hope that you'll be able to get her well again. I'll keep all of you in my thoughts and prayers. Please take care. (((HUGS)))
