Hi Happycats,
No ketones is always good! YAY!
Please forgive me, but I'm not familiar with what 100 on the urine strip means. What kind of urine strip are you using?
Could you tell us what dose of Lantus you gave him? And, what he eats. And, your general location, in case you need someone to teach you how to hometest? I'm in northern NJ if that helps...
Hugs,
Deb and Nikki -- and Giz, forever whispering in my heart...
