Hello, new member here. I have a 7 year old cat that was just diagnosed with diabetes. I need tips on the easiest way to check his blood sugar. I am using 28g needle, pricking on the ear, and I can't get enough blood. I feel bad poking him so many times. I don't know what I am doing wrong?! Any tips or tricks would be appreciated. Thank you!
 
Testing tips here: Hometesting Links and Tips

Quick tips: Warm ears bleed best. Link above has info on making a rice sock and other methods to warm ears. Press the lancet device firmly against the ear. Adjust the device depth settings. Try a thicker lancet and a matching device. Lancets are not interchangeable between different brands. If the device has a clear alternative site cap, use that so you can see where you are poking. Try the other ear.
 
I have significantly less experience caring for diabetic kitties than most of the members here, but I thought I’d offer my 2 cents as someone who struggled a LOT with home testing and only recently figured out how to successfully test every time.

I’m actually not joking that we spent multiple weeks with unsuccessful tries that would leave me crying on the floor.

The biggest game changers for me in no particular order:

1) Massaging my cat’s ear and getting it really warm. Moonie hated the warm rice sock, but I learned that she’d happily tolerate ear massages with my hands. So I warm up my hands in hot water almost until it’s so hot that I can’t stand it anymore. And then I gently and slowly massage her ear especially the tips until her ear and my hand are the same temperature.

2) Using 26g lancet. I felt terrible using a bigger lancet at first but I realized what really stressed Moonie wasn’t the prick but me messing with her ear. So it was way less stressful for us for me to use the bigger lancet and get enough blood in one go. I personally had a lot of trouble freehanding, so I bought 26g pressure activated lancets from Amazon. Over time as her ear learns to bleed better I will experiment with 28g, 30g gauges etc (https://www.amazon.com/dp/B081G4RC4P?tag=felinediabetesfdmb-20). Make sure to hold her ear with a cotton pad on the other side or you might poke yourself through her ear and mess up the test (which happened to me multiple times….)

3) Vaseline on Moonie’s ear before I test. Moonie has black ears and I used to never be able to see the blood before it’d get absorbed back into her ear fur. With the Vaseline the blood drop beads up.

4) Using my finger to scoop up the blood drop on her ear. Moonie would absolutely hate it whenever I’d bring the AlphaTrak strip by her ear and this used to be the worst part for us. But I learned she was totally fine with me quickly scooping it onto my finger and testing from there.

5) Lots of singing and treats and praise. The singing helped calm both my and Moonie’s nerves. I make up silly songs about what a beautiful brave girl Moonie is and how much I love her. It settles us both down and makes it an almost fun bonding experience. I save the highest value treats and only give them to her during testing. Now she will come running to the testing room whenever I call her in. During our testing process I would always praise her and give her treats no matter what, even if the tests were all failures. In the beginning I also limited my attempts to 3x, and then if it didn’t work, I’d wait 30-45 mins and try again. It gave me peace of mind (“it’s just three times, we can both handle it”) and I think also didn’t test Moonie’s patience excessively while I was still learning. The most important thing to me was that testing could become a joyful sustainable part of our daily routine, so on net, I preferred to go slow and not traumatize ourselves while keeping Moonie on a dose that was probably too low. Your experience might be different though, as I’d just gotten Moonie from the shelter and didn’t have that bond with her yet.

Keeping my fingers crossed! It’s so stressful and scary at first but I have no doubt that you and your cat will settle into this routine over time. Please give yourself grace and compassion during this learning process - I wasted a lot of time and energy beating myself up every time I failed, and it was just counterproductive in the end especially because Moonie could sense the stress and would get stressed herself.

I don't know if you've seen our information on home testing post. There's lots of information along with videos.

One other option is to use a FreeStyle Libre. This is a continuous glucose monitor (CGM). The sensor is attached to your cat's skin and you can read the blood glucose level on your phone. You don't have to prick your cat's ear for every test. The sensor lasts roughly 2 weeks and then you replace it. You do need to know how to home test in case the CGM fails.
 
One more thing: have patience. Few people get the hang of testing right away. It'll take lots of poking and figuring out what works best for you and your cat. I started with a hot damp washcloth in a baggie long ago as suggested by some members. It didn't work at all because the washcloth would get cold within seconds of being soaked in very hot water for a few minutes and wrung dry and my cat didn't like the sound of the crinkling bag so close to his ear. I switched to a rice sock which worked out so much better. Just take an old small cotton sock. Baby size is all you need but use whatever you have. Fill with about 1/4 cup of uncooked rice or dried beans. Knot the sock close. Heat in microwave until toasty warm but not so hot that you can't comfortably hold it in your hand for a few minutes. Wrap the sock around the edge of the ear and hold firmly for a good minute if you can. Hold the sock under the ear while you press the lancet device on the other side. The sock provides a firm surface to poke against and protects your fingers.
 
Like the other replies are saying, read those links to get a lot of very good info.

I will say that I was also struggling really hard getting enough blood for the test. I remember holding this squirming, uncomfortable cat in my lap as I kept stabbing his ears and nothing was happening. Two things were absolutely gamechangers for me:
  1. 23g safety lancets. I know that might sound really thick but it's what the vet used, my cat doesn't even seem to notice when I poke him, and it works every time. Also before I switched to the 23g I'd shine a flashlight on his ear and the whole thing would be colored red with bruising under the skin because I was poking him so much. Now I only have to poke once, and the flashlight doesn't show any blood in the ear except for at the most recent poke site.
  2. Squeezing around the poke like I'm popping a pimple
