Well, here's where I was going with that....
I'm thinking that if you get a number that you feel comfortable with for shooting, you could try half that dose. Like instead of 1u in the morning and nothing at night, shoot .5 in the morning, and if needed, .5 at night. The numbers look an awful lot like what I was getting with Bob just before he went OTJ, and I think she could be just about "there". I'm thinking that if you can keep the insulin working through both cycles, that might just be enough to get you numbers below 100, at which point you could stop shooting and see what happens. ECID (every cat is different) so you might not get identical results, but I think it might be an option you could try over the next couple days and see how she reacts. If you do try something like that, a +6 test would be ideal, so you got see how low she goes "at the bottom".
