Try to get spot checks in when you can. Right before you go to bed is an excellent time to get a test in because so often cats' blood sugar will be lowest in the pm cycle (between your night shot and the morning shot.) You'll see that his blood sugar will change a lot.
The
SLGS sticky suggests doing a curve once a week. You can either do every 2 hours for 12 hours, or do every 3 hours for 18 hours. Then you look at the lowest number that you've gotten on that dose and compare it to the chart on the sticky to decide what to do with the dose. With Lantus, you're always looking to answer the question "how low can this dose cause my cat's blood sugar to go?" The higher numbers will typically come down on their own if you get the nadirs (lowest numbers) into the correct range, so your dose decisions are based upon the low numbers. If that isn't clear, please do ask questions. We want you to understand so that you can see the reasons and eventually make decisions for yourself.
Take a look at this sticky "
Basics, New to the Group?" and do start a spreadsheet as soon as you can. The blood sugar tests need to be seen in context of how long it's been since the last shot to have meaning. The spreadsheet is an essential tool that we use - we're not vets here, so we use data to help people learn what's going on with their cat's blood sugar. Anyone giving advice will want to see the spreadsheet so they can look at the past week or so of blood sugar tests. If you have trouble starting a spreadsheet, just ask for help. We have a couple of people who will start it for you and then turn it over to you to maintain. They are very simple to use.
Ask as many questions as you have. We've all been in your shoes and remember how overwhelming starting out can be.
