I am so sorry about Binky's illness. I'm just seeing this thread. Is Binky having bloody diarrhea? Did anyone mention
HGE? This is a serious, potentially deadly situation, and should be addressed asap. I have read the previous posts, and understand there is no money. Now that I think about it: surely your vet has ruled this out, or s/he would treat Binky for it.
Prayers .....
