My cat was diagnosed about two weeks ago. We went back in for one Chuck and she goes back in in a week for her second check where they had upped her dosage of insulin. I am wondering if I’m actually giving her the insulin the needle is so small. I can’t tell if it’s puncturing her skin or not. I’ve seen some improvement as I’m not filling her water bowl as often does anyone else have a sure way of knowing you’ve done the injection? I can’t feel the needle puncture her skin.
