Your poor baby, I can only imagine what you're going through and the sheer heartbreak and worry for you all.
Bobby has been on chemo for 9 months now for treatment of GME (Granular Meningital Enciphilitis) and it was the Predisone which made him sick, not the chemo itself. I can only talk for Bob, but his blood tests are showing improvement month-on-month meaning the chemo is doing its job and it has been worth it all - he's had no side effects at all, we've only seen a massive improvement in his health as a result, but I know this is just his personal story, I hope it could be the same for every other furbaby.
I'm sending all my love and prayers to you all, your baby Oscar has the best care and love and you will do all you can to help him. Wishing you all the very best xxxx
