I'm sure the Micro would be fine. Both meters are popular with US members here. (I'm in the UK.)
When beginning to test, having a meter that works with a small blood sample is very helpful because you might only get tiny droplets of blood when you first start testing. (Tip: get some Vaseline or Neosporin ointment and smear a very thin film over the edge of the ear before doing the poke with the lancet. It will help the droplet to bead up instead of wicking into the fur, making it easier to get blood onto the test strip. Also, coarser lancets (e.g. 28 gauge) tend to be better when starting out, too.)
Testing Schedule:
1. Make sure Matty doesn't have any access to food from 2 hours before her next injection is due (unless she's running low, in which case you'd need to feed her to get her numbers up) to make sure that her preshot blood glucose level isn't influenced by food. It is necessary to know the fasting blood glucose level in order to make sure it's safe to give the next dose of insulin. I recognise that this can be a little trickier in a multi-cat household - kittens might be a little miffed at first - but it's important for safety. The two-hour fast may also help Matty's BG levels in the last part of the cycle because that's typically when the Vetsulin dose has more or less petered out.
2. 30 minutes before the dose is due, do a preshot blood test. (AMPS = morning preshot test, PMPS = evening preshot test).
(NB: While you have very little data, the general rule is not to give insulin if the preshot blood test is less than 200 on a human meter. However, for cats with a history of producing ketones or of diabetic ketoacidosis (DKA) more caution is needed since missing an insulin dose is a bigger deal for these kitties. If Matty has a history of ketones/DKA I recommend you post for help here and also speak to your vet if she has a preshot BG of 200 or less.)
3. Make sure that Matty has a good feed before giving her injection to make sure that she has enough food on board for the Vetsulin to 'work on' as soon as it kicks in.
4. Provided it is safe to do so, 20 or so minutes after the meal give the insulin dose.
5. Typically Vetsulin starts exerting its strongest BG-lowering effects any time from +2 hours after the insulin dose was administered. When Saoirse was on Caninsulin (same as Vetsulin) I'd watch to see when she started looking for food in the hours after her injection to get a handle on when the insulin dose was kicking in. In general I'd test at +3 hours after injection time, morning and evening to make sure the dose wasn't likely to take her too low. In the early days of building up your data picture for how the Vetsulin is/isn't working for her it would be great if you could get another test in at +6 or +7 hours after injection time. This will give you an idea of how long in each 12-hour cycle the Vetsulin is lowering her blood glucose (the duration). Most people do the later test during the daytime cycle. (Important Note: Per the hypo guide, if a cat is running in low numbers (close to or below 50 on a human meter) you then test much more frequently until you know that the cat is back in safe numbers and is going to stay there - but that's the exception, not the norm.)
6. For the time being, during the cycle keep to Matty's current feeding schedule as it is (apart from lifting the food 2 hours before each injection) because you know that thus far she has been safe with that routine. When you get more data on her blood glucose levels you may be able to refine her feeding schedule to work better with the insulin (again - might be trickier in a multi-cat household but we can cross that bridge when we come to it).
We have a spreadsheet template that you can use to record Matty's test results. It looks a bit busy at first glance, but essentially it's just a grid in which you fill in her numbers. It's an incredibly helpful tool because it helps you to visualise what's happening - much less 'thinky' than trying to work things out in an already frelled head (I speak from experience!

). Also you can put a shared link into your forum signature so that other members will be able to see how she's running and they'll be better able to help you with suggestions about how to improve Matty's regulation. I'm including a link to the instructions on how to set up a spreadsheet. If the prospect of this is overwhelming to you just give a shout and one of our members will be more than happy to do the initial set-up for you then all you'll have to do is fill in Matty's BG readings as you go along.
FDMB Spreadsheet Instructions
Hope the above helps you. Be sure to ask about anything that's unclear or confusing (I'm very, very tired at the moment). I also hope that, now you've found FDMB, you won't feel quite so isolated or overwhelmed about things feline diabetes. We'll do all we can to help you improve things for both yourself and Matty.
