Hi! You haven't been on Lantus very long. Sometimes it takes awhile to find the right dose. You're feeding low carb wet, but I seem to remember you have one kitty still on dry? If so, are you sure LB isn't getting any? I found that my Cat was finding pieces that my kibble addicts had spilled even though I thought I had cleaned them all up! Also, when a cat has been in higher numbers for awhile, their body becomes used to it and it takes more insulin to break through the resistance, but then they start to come down. I would give Lantus some more time before considering a change. Having said that, the best insulin is the one that works for your kitty! Perhaps
@Bobbie And Bubba can shed some light, as she's used both insulins.
