Perhaps you could point out to your mom that when her blood glucose is running low, she knows what to do. Bay doesn't. The kitty can't adjust his own dose.
We are very sensitive to safety issues and hypoglycemia can be a very real safety issue. Having data will let us know if a dose increase or reduction is needed. If you don't think the vet is up to speed (and you've done your research and know what the answer is to that issue), then you need to have information you can pass along to us so we can help without putting Bay in jeopardy.
