These 20kg cattle salt likes can be bought for less than $5 at most feed stores in the Maritimes. As far as I can find on the internet they contain 99% NaCl ( Sodium Chloride ), Cobalt and Iodine. I was wondering if it would be safe to put these out in the field and let the deer lick them in order to draw them in for pictures, bow hunting and to compliment their diets.
