Hello there and welcome!
This is a great site full of helpful pet parents and lots of great info to help you and your kitty with diabetes management.
You can post medical related questions to the “main health forum” this board is just for general intro.
Also good to set up signature in you profile, that will show your cats details and then people can better help you if they know more such as age, weight, type of insulin, type of food, other health issues, etc. this can always be changed or added to later, see the bottom of people’s posts for example.
If you need help, people are very friendly here and are happy to help. In the meantime, look at some of the “yellow stickies” on the tops of the boards for more info.
