hi lyn
i do not know much about diabetes in animals
but ive been insulin dependant for well over 25 years
and symptoms like
thrush
cystitis
persistant thirst
re occurant abseceses
etc etc
are all showing a poor blood sugar control
most of these illnesses thrive on sugar
im hoping you can get the cats blood sugars more stable
you and your vet are obviuosly working so hard
