A better explaination about taming

[Cyberpangolin]

When you want to tame an animal / a npc, you have to give it something.

BUT

there is nothing to tell you what to give.

After discussion with @Darcidride , it could be better that right-clicking on the animal/npc says "Not tamed. Give some XXXXX to tame" instead of the simple and useless "Not Tamed."
