Horse's & Salt Blocks-Waste of your MONEY!

A cows tongue is ruff ,
 making it easy for the cow to lick a salt block and get minerals into him.

A horses tongue is smooth , where it cannot get any salt from a block due to the saliva that makes the salt fall to the ground, 
you as a horse owner  are wasting your money- 
Plus salt blocks are glued together -toxic - Loose Redmond salt is best.
