Ancient times, when there was no production of insulin people used to collect it from animal pancreas. This pancreas insulin provides them a quick recovery and was very helpful. But nowdays, factory is manufacturing insulin for diabetes prevention
I’m failing at giving my poor cat insulin. Last night I don’t know if he even got it, this morning I poked right through. I try to give it to him while he’s eating but I may have to wait until after. The vet showed me and of course I neauled it on the 1st try but I am not doing so hot on my own 😢
