The Epogen does seem to be helping her! I'll mention the alternative med in case it becomes useful. darbepoetin (Aranesp ®)

Lara, I don't think Epogen makes the kidneys better...but maybe the one remaining kidney doesn't work as hard because the anemia is being healed? That could be.

Hopefully the Clindamycin works - Puddy wouldn't be the first kitty to have a recurrence of a UTI! When something "normal" happens during crisis illness, it easily becomes part of the crisis.

HUGS and prayers to you and Puddy.
