Collared

Okay, so I have a series of captions loosely based on the idea of a shop somewhere that sells collars which turn people into creature-girls, sometimes with certain personality traits tied to them (anything from as simple as making them feel a little happier or behave a little more cat-like to wanting to act as a bodyguard and protect the one who put the collar on). This challenge is to make a caption that could go in that series, using the following image:




The only real rule to this is that only the person who put the collar on can take it back off; other than that, this concept is meant to allow for a lot of freedom on how these things work. So...have fun with it!
