Found out my vet is following the older, non-tight regulation protocol - 2 weeks, curve, adjust, repeat as needed.
*sigh* and she goes to continuing ed stuff, too. *sigh*
And an observation to test: it seems that if I mix 1 large can (13+oz) of Friskies Turkey and Giblets with 1 regular can (6-ish oz) WalMart Special Kitty Turkey, it doesn't incite a feeding frenzy and is consumed more slowly, resulting in lower glucose levels. Nothing like live experimentation.
