Welcome Claylady and Jesse James!
What led to Jesse's diagnosis? Was it a routine check-up or did you notice other issues? Lantus is a great insulin for helping our extra sweet Sugar Babies! It is one of the best and many cats (upwards of 86%) achieve remission while on it (i.e. they no longer need insulin). This is based on the Tight Regulation Protocol Sue linked to above, which includes a good insulin, home-testing, and a species-appropriate diet.
You've already got a great insulin. :thumbup
Next step would be to look into
home-testing. Depending on where you live, there are some great, inexpensive glucometers that will help you know how your kitty is doing at any given moment and let you know whether or not it's safe to give a shot or if the dose is too high/too little. In the US, most people prefer the ReliOn brand from Walmart because they're the cheapest around. These are also the same as the Arkray Glucocards available from
ADW if you don't like shopping at Walmart. If you're in Canada, many people there use the Bayer Contour meters.
Finally, once you have the home-testing down, a change to a low carb, high protein diet is recommended. As Sue mentioned, you don't want to make this diet change without home-testing first (or stopping insulin all together) because it can significantly reduce the need of insulin. Some cats have even got OTJ (Off The Juice - not needing insulin) through just a diet change alone.
Catinfo.org is a website on feline nutrition written
by a vet and also contains a
food chart of the nutritional information for most commercial cat foods (you want anything less than 8-10% calories from Carbs, Column C).
And don't hesitate to ask any questions or ask for clarification. We've all been where you were at one point or another.
