Melissa, glad you're willing to learn to home test! It will really save you money, plus give you a lot more control. If you're like me at all, you need to have control of everything (my BF says I have control issues ha!).
First things first: meters. You can use a human meter. No need to buy the expensive pet meter vets sell. Many of us use the relion brand from Walmart. I used the relion confirm. Didn't require too much blood and the strips weren't overly expensive. You don't have to use that brand, just a lot of folks do. When you buy the meter you want strips to match it (they should be right there by the meter) and lancets. We suggest getting the lancets for alternate testing sites at first...I think they are like 26 gauge? They should say alternate test site on them. If not, ask the pharmacist for them. You can move to smaller lancets over time, but it's easier to start with the bigger ones. Also, you may want to get some neosporin (gel, not cream) with pain relief. I found it helped the blood drop bead up and I at least comforted myself thinking it was helping stave off infection. Some folks use vaseline. Some use nothing. I think something would be helpful, at least at first.
While you're working on getting your supplies together, I suggest finding a place to test. I had a towel I kept in the kitchen. I put it on the floor by the fridge. Gypsy quickly learned the routine and would go there when she heard the box of lancets rattle. I think it might be easier if they have a "place" they always tests since they know what to expect. Take Goo there a few times a day, rub his ears, pet his head, and then give him a treat. Get him used to having his head touched in this spot and then a treat and that will help.
Does Goo like having his head touched? Gypsy loved it. Most people use something to warm kitties ears to get the blood flowing. I just rubbed her ears, but some people use a pill bottle filled with warm (not hot!) water or a rice sock (baby sock filled with rice) that they warmed in the microwave. Gave them something to hold against the ears to warm up and something to push against for the lancet. I just used a cotton ball or my fingers (it was just easier for me).
I don't want to overwhelm you and that's an awful lot. If you want to watch some videos while getting supplies, I would. Here's one I've watched some of:
It's really not hard. I know it seems it, and the first few times can be tough (tougher on you usually!), but you'll quickly get the hang of it. And it will give you a sense of control, plus allow us to really help. We can definitely help you too! once you gather the supplies, let us know and we can walk you through this.
Please ask any questions you have! I know that was a lot of info at once.
