I'm so sorry to hear this. My Ziggy had a mild form of pancreatitis and luckily she only had to be in the hospital for 24 hours.They gave her fluids, pain meds, antibiotics and later they force fed her and she was able to keep it down so then I brought her home and she was ready to eat on her own. They gave me Hills A/D and you can mix it with water and then put it in a large syringe to force feed Paris if you need to. Ziggy also got vitamin B-12 shots to help to stimulate her appetite and they really worked. They gave her one and then I gave them to her weekly for about 6 weeks or so. I sure hope that she'll start eating again and will be able to gain some weight back. Lots more prayers and positive thoughts are being sent her way. Please take care. (((HUGS)))
