This was taken on the 16th street mall in Denver, Colorado. Me and the Mrs were out and about with the twins and we came across this large group of people. Upon closer inspection we found these 'pals'. This was the best angle I could get because of the crowd.
(not in photo: There was actually a smaller rat snuggling with the momma rat but the crowd kept me from that angle. Right after this photo was taken some passer-by put a dollar into a hat near the scene. The dog, mistakingly thinking the man was robbing his human, snapped and almost bit the gentleman.)
