Hello,
have you thought about setting up a spread sheet - track your kitty's BG numbers and to enable us to help you interpreting it?
There instructions are
HERE but there are people who are capable of helping you out in a more practical way - my SS was set up by somebody else in the Group and I 've been using it ever since.
I am very sorry but unless I can see the BG numbers in sequence in the Spread Sheet I am not able to offer an opinion...
If I am to answer I'll need to know :
the current insulin type and its dose and how it is administered;
do you test before he eats?
do you test prior to injecting?
are you outside of the US and refer to the BG reading in the World measuring system?
what type of glucometer are you using?
Again, sorry, need to have more info to offer an opinion...
But good luck to you and your kitty!
