I most certainly have Halo in my prayers right now. I hope that she is given another chance... until you know for sure, the best thing to do is spend some time with her quite often and keep an eye on how she acts. I'm very shocked to hear her health problems...that's what happened to my Boots. He developed a big tumor next to his heart that could not be fixed because by the time the doctor diagnosed the problem, it was too late. We had taken him in before, but the previous vet continued to tell me he was fine and that he was just overweight. So we switched vets... and what do ya know... I know my baby and something just wasn't right. I can only hope you caught poor Halo's condition in time to be able to be fixed. I'll be sure to pray for her. Please keep us up to date as to how she is doing.
