Cannot take blood from cats ears

Rachels Kiska

Member Since 2026
My kitty Kiska has recently been diagnosed with Diabetes as a result of long term steroids prescribed for allergies. She’s 13 and was diagnosed 4 weeks ago).

She currently has nerve damage in front left paw (knuckling) and suspected nerve damage in back legs (weak and although have mobility suspected sensory damage).

She is on 1.5mmol caninsulin after meals at the moment.

I have a major problem getting blood from Kiska for reading of glucose levels. Her ears just won’t bleed!

I’ve watched dozens of videos, warmed her ears for 5 mins with a wheat bag, pricked her ears a dozen times (bleeding myself a couple of times through her ears!) all around the “sweet spot” and cannot get more than a tiny bead of blood which I’ve achieved only once or twice. Not enough for a reading. Even the vet can’t get blood out of her ears.

She also won’t let me get to her paws, I’ve managed a couple of times but they are also very hard to bleed and she won’t stop fighting despite all cuddles and treats. She’s good natured so not biting of scratching, just insane amounts of wriggling and conscious it’s not a long term solution.

Tried a continuous blood glucose meter but was constantly saying she was over 22.1mmol which she was showing no signs of in behaviour or physically. Obviously you are supposed to check against a blood test which I can’t get from her! Took her to the vets after 24 hours just in case and they said their first reading on her was 8.3mmol before went up to 17.3mmol which would be normal from being at vets and traumatised by being bled (from the vein).

I am not squeamish, I’ve injected myself many times when going through ivf, I just can’t get blood out of my adored but wriggly ear bloodless cat!

I cannot believe I am the only one that’s ever experienced this and just wanted to see if anyone has advice or suggestions on how to cope.

If the lancet is too thin, you won't get blood. Use 26 gauge. You can use any brand of lancet and the matching device.

The sock needs to be really really warm. Try uncooked rice or dried beans instead of wheat. Wrap the sock around the edge of the ear and hold firmly in place. If it's too hot, your cat will flinch and try to move away. Let the sock and ear cool a bit and try again. The vein that runs along the edge of the ear will plump up when it's warmed up well.

Hold the sock under the ear. Press the lancet device firmly against the other side of the ear, using the sock as a surface to press against. Poke. If no blood, adjust the device depth setting higher and try again. It's easy to just miss the ear too so move the device over a bit. If the device has a clear cap, use that so you can see where you are poking.

Some cats have only one ear that will bleed. Try using the other ear.

Have patience. Few newbies are able to get blood right away.

Caninsulin is not a good choice for cats. It's made for dogs. What country are you in?
 
Thanks, I was using the lancet that came with the device there’s about 200 of them and they start thin and get thicker.
I’ve tried varying the depth but when I wasn’t getting any blood to be honest I started just leaving in the deepest setting. And yes I’ve hurt both her poor ears equally!

I’ll try again using your suggestions.

Caninsulin, yes I’ve realised that, I’m in the UK, I’m going to be asking for a different insulin next time I go to the vets!
 
Hi squeem3

Just an update. Had no problem getting blood out of her ears now, it’s suddenly easy peas!

I’m not sure if it’s because the weather is nicer or because her blood sugar is now much more under control but her ears are now lovely and warm without the wheat bag and bleeding just right! She has also started regrowing the fur on her ears so I’m leaning towards the diabetes causing poor circulation to her ears.

Thanks so much for the advice however as it’s really helped when her ears were colder.

Anyone that is having trouble getting the blood from the ears be aware it gets easier as their blood sugar gets under control!
 
the capillary bed develops over time as well, as long as you keep trying. it is said a cat's ears "learn" to bleed.

Great job "sticking" with it :)

personally I thought the whole thing was impossible and I would never get a blood droplet from my cat. Just the idea of it seemed ridiculous to me. I'm living proof that anyone can do it!
