Little Fawn's Salt Lick teaches you how to summon a Little Fawn, a Rare Critter battle pet.
This item is obtained when you complete the Lil' Game Hunter achievement. This requires you to have learned 75 different kind of companions.
A Friend to Fawn Over
I understand you've managed to give even that mischievous Stinker a warm and loving home... I was hoping you might consider taking in another wayward orphan?
This little fawn is a shy one, but you'll have no trouble winning her friendship with the enclosed: her favorite salt lick!

- The "Lil' Game Hunter" achievement name is probably a reference to the «Big-game hunter» who is a person who likes hunting large animals for parts as trophies.
