If you use the lancet correctly, and are not poking the actual vein, but are hitting the "sweet spot", it's very hard to tell that your cat is even being BG (blood glucose) tested at home.
Take a lancet or two in, and show the vet, and even more importantly the vet techs, how you do the ear testing. You'd be surprised how this "skill" is not widely known in the vet community. Usually, the vet clinics get the blood from a leg vein. I'm surprised they are using the ear.
Paw pads on a cat are another place that can be poked with a lancet for testing.
Here is the "sweet spot" diagram we use here. Don't know if you can print it out, or copy it to your phone or something, so you can show your vet office.
Testing
We all know the basics:
- Warm the ear with a rice sock or a warm washcloth wrapped in a plastic bag.
- Either freehand or use a lancing device; new members usually start with a larger gauge lancet such as 28g or 29g until the ear learns to bleed; then progress to a 31g or 33g which are finer.
- Be sure to poke in the "sweet spot" and not the major vein that runs along the length of the ear. Poking the vein will not only hurt, but will result in a lot of blood. The sweet spot is on the edge of the ear.
But did you also know there is a particular way for the lancet to be used? It has one side that is beveled so the sharpest part goes in first, if used correctly.
