I can't answer that question but if your choice is a higher BG for a period to clear up a UTI, I think I would take the higher numbers.
I used it for only 4 days on Shadoe and her numbers did not go higher, but I think they were already higher because she was sick.
I did take the rest of the meds back and switched to Zeniquin because whatever was ailing her, clavamox was not helping. The zeniquin is helping.
I hope kitty is better soon
