I know one of the tricks to scent a rodent for purposes of enticing a non feeder, or a snake that only eat mice to eat rats, or switching from live to frozen thawed etc. is to scent the rodent.

I know one trick is to rub the frozen thawed rodent onto a live rat or the rat bedding. I do not breed or keep rats and am not going to as it seems silly to keep them just for their bedding. I have a friend who does, but he lives far away and it would be a pain in the butt to have him give me bedding each time. He would hate me after 2 weeks. I can ask him for some bedding once but if I keep that sealed in a ziplock, how many times can I use it before I would need new bedding?

It would be far easier if I could try some of the scenting methods that I can get the stuff from a supermarket. I heard of chicken broth and tuna juice. I don't know to do that though if someone can enlighten me. I searched and I just see people say dip it, but you mean you feed that stuff to the snake soaking wet? You should heat up the broth/juice and then dip it?

Also, someone mentioned sodium free chicken broth, not sure here is such a thing, only chicken broth with no extra salt ADDED (still has sodium), and also lots of people talking about using BRINE in tuna cans which is basically SALT WATER. What's the issue with sodium?
