I recently went through some difficulty giving my cat his insulin injections. It seemed to be fine for a few weeks and then he was flinching and running off mid-shot.
These are the things I did which collectively seemed to help (thanks to great suggestions from a lot of members!):
1. Make sure to give it in different locations, rotating sides. I was giving it more towards his shoulders on his sides because that was easiest and I was rotating sides, but I needed to use the mid-flank more because he started developing scar tissue and I could feel that his skin was tough when I was putting the needle in. This can be really painful for them, and also they say the insulin isn’t as well absorbed when injected into scar tissue.
2. Make sure to warm the insulin in the syringe by putting your fingers around the barrel and rubbing. Cold Lantus stings- I am not sure about the other insulin types.
3. I started to sing to him, also, and this calms him down and also calms me down so I’m not too nervous about giving it, which they can sense.
4. I also give while he is eating.
5. I use a headlamp so I can see what I’m doing. Biggie has short hair, but I couldn’t see anything. The headlamp helps tremendously so I don’t feel like I’m shooting blind. The headlamp also helps a lot for the ear tests.
6. I use 31 gauge 5/16” needle, and I think the short needle is less of a poke and more comfortable. The large gauge/skinny needle also helps.
Good luck!
