New to the world of feline diabetes. I am having difficulty giving insulin injections. My cat is muscular and skin is not very elastic. Any suggestions

Hi Jeanene, I couldn't use the 'tenting' technique with my first diabetic (that was because he was a fidget). So, the technique I used was to grab some skin on the scruff between fingers and thumb of my non-dominant hand, then pull that up and tip it up slightly. Then I'd give the shot almost directly downwards into the skin that I was holding, about mid-way between fingers and thumb. Doing this meant that I could still give the shot even if he moved a bit, as long as I was holding onto that skin. And it also meant that there was no danger of my accidentally pricking his flesh if he suddenly moved, because the depth of skin in my hand was greater than the length of the syringe needle. If that makes sense...?I am having difficulty giving insulin injections.
@Chris & China (GA) has a technique where she rolls some skin on the scruff back, and (I think) gives the shot where the fur naturally parts. I'm pretty sure she has a photo of this... (Is that right, Chris?)
