I remember when I was young that my Uncle always liked to tell me and my cousins that they were going to go muskrat hunting (in pretend of course), and it always made me laugh. Also, my last name is Muscat, and it sounds similar. Also, during 5th grade I got a character counts award where my name was spelled on the physical certificate as "Justin Muskrat" (how does the school even do that? I have received awards before with my name correct, and my name must be on a billion other things in their records too! The principal even knew me personally!). The name Muskrat Catcher finally came into existence when I was creating an Xbox Live gamertag, and my username that I had used for everything else up until that point was taken (It was Wjustin up until that point, which stood for "Webkinz Justin". Good thing I finally changed it, lol), and viola! Muskrat Catcher was born! I really like the name, and it is now my username for everywhere that it can fit
