Hi Kenneth and extra sweet baby! What kind of insulin are you using? 6 units is a LOT of insulin. When you feed, the numbers will go up from the carbs in the food. What are you feeding?
How about posting over in the 'Feline Health' forum giving us that info above as well as a bit about your cat and we'll all see if we can help. The micro is a good meter - it's my favorite of all the meters I've used over the years.
See you there!!!
