ok - don't panic
We all had problems at first - the cats ears do not bleed easily to begin with but after a while they develop more capillaries and bleed better.
It does get easier!
My cat wasn't a wild cat but did hate it at first - hid under the bed, I had to pull her out, she hissed/spat etc..
Now when she hears the treat bag, she (and my 2 civies) come running. It will get better!!
Treats - most cats love PureBites Freeze Dried Chicken - Petsmart there should have it and you can by the dog version (same, just bigger pieces that you break up).
Start with giving Squeak a treat while rubbing, holding etc.. his ears - let him realise you're not hurting him and its actually yummy as well.
When both of you are calm - maybe an hour or so later ?? - try to warm his ears. If he doesn't like the rice sock, try an old pill bottle with warm (almost hand hot, but don't burn him) water in it, otherwise, just rubbing his ears for a bit should stimilate the blood flow.
Then if all's going well and both of you are still relaxed, try to poke.
Have everything ready - put a smear vaseline on first to help the blood bead, have the tissue/cotten ball folded ready, have the strip part way in the meter, have more treats out and more you can easily get to...
Then try to poke - if you get blood great, if not try again in the same place - it might stimulate it.
Otherwise, you can try the other ear - give more treats (very small sprinkles/pieces).
If you get blood try to get it on the strip, if not get it on your finger nail and then transfer to the strip afterwards.
No matter what, stroke, talk to Squeak etc.. -
It took me about 2 weeks to be really comfortable - first few days were pretty awful but you just have to keep trying. And, its better that at the vets!
