The same thing happened with my cat, I think I replied on your original post when Jaz was sick. Had to do the feeding tube and all that too!! The good thing about the liver stuff is once they start eating the liver will go back to functioning normally, at least Midnight's did, but getting them to eat soon enough is the problem. I went through this twice with him (a year apart) and both times nothing could get him to eat and when we put the tube in I fed him it was like one day he just said "oh, yeah, I'm suppose to eat on my own" and he just started eating again! I don't remember how long he had the tube in, but I don't remember it being very long at all. I hope all turns out well for you and Jaz, good luck.
