Welcome to the best place you never wanted to be Tommie!! Don't worry....we've got you! Just take one step at a time and soon you'll be doing the sugardance with the best of us!
Here's some information on
How you can help us to help you. Holler if you need some help with any of the technical stuff.
Betty is right. Lantus is a better insulin for most cats than Vetsulin, but we've had some cats do OK on Vetsulin too.
Have you actually started giving insulin yet? Have you changed Stella to a low carb canned or raw diet?
If you haven't already started insulin and Stella had no signs of ketones, there's no rush to start. This is the safest time to change the diet and learn to home test to see what Stella's BG runs at home when she's not stressed at the vet as well as how any diet change is affecting her numbers.
Don't want to overwhelm you all at once so there's some things to get you started!
Remember, big deep breaths....in through the nose, out through the mouth. If you're freaked out, Stella's going to think there's a reason she should be freaked out too which just makes it harder on both of you!
