if you haven't yet learned to give them, pls make sure your vet shows you how to give meadow subQ fluids when you guys leave. fluids, pain meds (bupe for cleo), and injectable pepcid can help soothe an irritated pancreas the next time she seems to be starting a pancreatitis flareup and hopefully will prevent such a severe attack from occurring again.
if you can, wear a t-shirt for a few hours to get your smell on it and bring it to meadow to sleep with. it is comforting to have your smell there with you. otherwise you could put a clean sock in your bra for a while to get your smell for her.
very glad she's feeling better, and very very glad you got her to the ER. (((HUGS)))
