Can anyone answer this question

[DOUGTM1SS]

I have been reading about humulin - N and Humulin - R, I don't see much difference except in the price and the N is used by vets and R is used for humans.
I was reading 1800petmeds since I just got a new dog and wanted to save some money on vet bills for vacinations and I saw humulin-n for cats and dogs, well since some of the sauce we use is for vets, I would ask if anyone
can with any attention to merit answer my question.

What is the difference between humulin - N and humulin - R and could I use either one or do I need to use the one for humans only?

I know it sounds like a dumb question, but the only dumb question is the one that doesn't get asked, right.
