Hi Amy, It looks you Bhooma was able to give you great advice this morning! And it looks like perhaps Tibby is turning the corner on her diabetes. Take a look at Henry's condo and spreadsheet - there's a cat who turned the corner - so you want to be prepared for how to handle those ever lower numbers.

You may want to reach out to Robert and ask him for advice as he's just had a nice opportunity to learn how to handle lower numbers. That's how we all learn - from one another and from the experienced members who've been around for a while.
I hope this is Tibby's time to shine! Enjoy your day!
