CRF in Alex

Well, I just got the bad news from the vet. Alex, who is 16 years old, is
just beginning CRF. The vet told me in addition to switching his food to NK,
I should begin weekly subcu fluids. She stated that by so doing, since he is
still in the very early stages of the disease process, it is actually
possible to reverse the situation and return him to relatively normal kidney
function. Has anyone ever heard of this before (that beginning subcu right
at the beginning of CRF can reverse the process?). I did successfully cure
him of diabetes with Lantus insulin, and I never would have thought that
would be possible. Now that he'll be eating NK, we are going to have to keep
a very close watch on his blood glucose to ensure the diabetes doesn't
return. The doctor recommended that we repeat bloodwork to reassess kidney
function in about three months. Does anyone have any thoughts on any of
this?
