I'm making my own ground mice and I'm curious about the glycerin as I don't have any.. Instead of ordering it and paying the shipping , can I use mineral oil instead ? This I can buy at the feed store . I'm curious as to whether this is an alternative or a train wreck ! Thanks

If you just want a small amount you can buy glycerin at a drug store. There are different kinds of mineral oil. The stuff at the feed store is veterinary grade. Only lowers the freezing point a few degrees lower. Not a real good antifreeze.

Alot of old formulas call for paraffin oil. But as danny said it wont stand up to the cold as well as glycerine

Thanks fellas At least now I know.. Guess I'll be looking for glycerine for my mice..
