That number is fine, 178 = 9.9
He doesn't understand that you are trying to help him. Give Diesel a a chin scritch from me.
What part is he hating? Maybe we can help you with ideas for making it better.
1. Have you tried bribes during ear testing? If Diesel is food driven, Diesel may come to associate the treats with the testing process and be more cooperative. Bribes can be brushing, play time (before or after), talking to him, some pats and chin scritches, telling him "what a good boy you are Diesel".
2. Have one spot for testing and say "Diesel, test time and then you will get your treat." Maybe a bit of something like triple antibiotic with pain relief to take the sting out before you test. Not too much, the tiniest bit to numb the ear. Can help to see the blood drop on kitties with black ears and ear edges. Wipe off any excess.
3. Are you aiming for the 'sweet spot' and not the vein?
4. I always thought this
ear testing psychology document was a good explanation of the 'zen' way of testing, a calmer way of approaching the process.
5. Have you tried singing to him or some nonsense talk, say anything, like you would to a baby, doesn't matter what you say. Tell him about your day, but with a smile in your voice. Cats pick up on our stress and that can make it harder.
Some cats are ok with ear testing. It's tough in the beginning to get your cat used to this 'new thing, what the heck are you trying to do to me mom'' Some people use the paws, but the paw pads toughen up and can be harder to get blood from weeks or months down the line. Pros and cons to doing it both ways, paw pads or ears.
