Mr. Bean & Rocky didn't know what to think of each other the first day they met.  Now after a few days have gone by, they've come to appreciate each other's company.  Mr. Bean took the first move.  I think he decided that either Rocky was going to look at him as beef jerky, or if took a chance a rubbed up against him, he would become his ally...protecting him from every other dog in the neighborhood.  It looks like Rocky's decided that Mr. Bean is a worthy cat.
