So I was looking at one of my pet's profiles and I saw something that said 'No title'.  I clicked on it to see what it was, and it said 'none'.  So what is a title?

It is like a secondary name almost. All the pets I breed have the title Insane Asylum, as an example. It is a way to organize your pets, or show they are from your breeding lines, just for fun, or other such things. Below is a link of how to make a title if you want do to so.
