When did you start using Lantus and how long till regulation? June 23, 2005 we started Lantus. We continue to struggle with regulation, however we manage to stay under under 250 most of the time, and sometimes get down around 100. It took 9 units bid to get him into this range (he weighs 23 pounds), we are now giving 7.5 to 8 units bid. 3.) Are you feeding your cat a low-carbohydrate diet? 4.) Has your cat gone off of insulin? No. No way.
