Hi Melanie, I don't know what your vet is waiting for and I think it's marvelous that you like and trust her. That's a real plus. Some vets tell people not to bother, some want people to come into the office for weekly tests which can run into some money. Some vets tell people it hurts the cat, most cats don't like their ears messed with, and have very few nerve endings in the area we use. Some vets tell people it will destroy the bond between pet parent and pet, it doesn't. Many members report that their babies come running so they get their special testing treat. I have read that most vets just aren't educated enough in Feline Diabetes and make recommendations in ignorance, not malice.
I just encourage every new member to home test, because I know it's a very important tool in keeping your kitty safe, as well as knowing how the insulin is affecting the body. We shot blind, like you are doing, and Idjit had a hypo. Others here have done the same thing, and some fur babies have died or ended up at Animal Emergency. Humans test before injecting, so they know if it's safe to do so. You wouldn't inject insulin into a child unless you knew if it was safe, same principle. Many members use the Relion human meter from Walmart, because it's affordable and the testing strips are affordable and in most cases, easily accessible. Some members use a pet meter, like the AlphaTrak2, it is more expensive, the strips are more expensive and you have to order online, and wait for them to arrive. If you go through a lot of strips and run out before you have a new supply on hand, you are out of luck. Some members that use the AlphaTrack2 use FreeStyle Lite strips and that works for them, they order from EBay and get good deals.
My recommendation is start simple, get the Relion Confirm or Micro meter. It takes a very small drop of blood
Relion Confirm or Micro Glucometer from Walmart
100 Test strips
Cotton balls or rounds
Vaseline
28 Gauge lancets (It's up to you if you want to use the lancet device)
Pain Relief Ointment
Test at least before every injection on your 12 hour schedule, and then when you can during the day to see how the insulin is affecting Sam, find what his low point is. Testing at your bedtime is also good, most cats go lower at night.
Another note: it's really important if you are transitioning to low carb wet food to test. This lowers blood sugar, and if you are not testing you may not be able to detect or prevent a hypo. We transitioned Idjit off dry to low carb wet food and his BG went down FAST. Within a month, with the insulin support he was in remission, off the juice, no more insulin. If you aren't going to test until you get home, don't change Sam's food and take a chance. We still test Idjit, every so often, to reassure ourselves that the remission is holding.
I am sorry this is long, I suggest again that you bring these questions and concerns to the Main Forum so that other members can respond. Also, it would be good to know what type of insulin you are giving and the dosage. Just click on this link:

I am also giving you a link by and for other members about home testing, so that you can see how important this issue is:
