Has Lucky been checked for kidney problems? When my Puddy throws up bile, it's because her kidney is acting up again which affects the liver, thus, the bile. After she gets some subQ treatments, it usually snaps her out of the nausea. Is Lucky dehydrated? If so, a subQ treatment would probably help.

I'm sorry to hear about your Dad but it does sound like you have a good option. I hope it works out for you real soon. It's tough, I know, but it appears that better times are ahead for all concerned once he gets situated in his new surroundings.
