Help Gerri Survive Poisoning

Hello friends! This is my baby girl Gerri, and she is not doing so hot currently. She has eaten a mouse poison called Selontra due to some misinformation from a rodent exterminator, and will die due to organ calcification if I do not keep her hospitalized for the week, with a long out patient care plan afterwards to keep her kidneys in check. I do not have the funds for something like this, and that is why i am asking for your help. Any help would be greatly appreciated, as I do not want to loose my friend.
