Well it sounds like Ms Josi is rallying, which is great! I have to say, it didn't look so good last night, but now she is getting up and eating and looking alert, it seems good.
Our Blaise always loved her tucker and we always figured that when she stopped eating that it was a sign we had come to the end of the line, and thats how it went :( The last few days she would barely get up and no food tempted her, no cheese, no dog chocs or jam toast.
So I think if she has her appetite and her eyes are alert she might well pull out of this, for a while at least.
Best wishes to you.
