Is there a Mouse in our House?

So I went to get something in the other room and when I came back to the kitchen this is what I found.
Notice the bite marks Mikey works fast!
Can you believe that kiddo! He then had the audacity to take another bite in front of me as if nothing was wrong with this.
It may have been because I was laughing hysterically. I wonder when Mike will notice the bite marks on our block of cheese.
