Start getting your kitty ( what is your kitty's name) used to rubbing the ears, then reward him or her with a low carb treat
Try to do it in the same place all the time so he associates that he will be getting a treat, Believe me it will become easier
You can even try filling an empty prescription bottle with warm water and hold it on his ear for awhile, I had seen a member does this
After you draw blood and test get a cotton round and press gently for about 10-20 seconds to stop the bleeding
You can also put a small amount of Neosporin Ointment with pain relief, make sure you buy the Ointment and NOT The Cream if you think his or her ears look really red
