Rattus has been sporting this lab coat for a while. It's almost as old as he is. I'm quite proud of it, as I made it myself (I bought the over-sized lab coat itself from a lab supplies speciality store) but I had never showcased it properly in spite of all the compliments it gets at furry cons. I thought it about time to make up for that oversight. You can't see it properly in the photos, but it has lots of little stains which I think makes it look more authentic. And, yes, I enjoy playing with rat stereotypes.
