Took me a whole morning and many phonecalls, but I've finally got the erythropoietin for Baggy.
Baggy lost another 0.05kg today.
We've given her the first erythropoietin jab. Have to wait for 3-5 days for the body to respond. Praying hard this will help.
I've spoken to three vets - all three did not recommend blood transfusion because it is just "buying time" and does not address the cause.
Thank you everyone, for all your help.
