Here is a shot from this past Tuesday of Sushi refusing the first rat I offered. I had mistakenly ordered weaned rats (was feeding adult mice, avg. 23g) and the smallest one in the package was 35g. So, on top of it being a rat, it may have been a bit big. So, I ordered some rat pups that will be in this Tuesday, and we will try again with a more appropriately sized meal.
On a side note, I apologize for all the typos above. I typed out most of this thread on my phone during an uninteresting meeting at work, and I didn't catch the errors until it was too late to edit them...
