My cat's just been prescribed EPO.

He recently reached end-stage renal failure. For the last week, I've been giving him subcutaneous fluid treatment and various medications. Today was his follow up appointment, and the vet said that all of his stats are noticeably better except his hematocrit levels. So, he's getting a blood transfusion and a week of erythropoeitin to see if that counteracts the anemia.

My warped sense of humor finds it funny that after all I've read about EPO in bike racing, I'll now be administering it to my cat
