The letter "R" stands for "rescue". R3 is one of the four cats found abandoned near my father's office. I took them in temporarily because the area is not safe, i.e. dogs and cruel passer-by.
R3 is very, very manja. He would roll over and proudly show you his round belly. He easily purrs whenever you came near him or he near you! I do hope R3 gets a good home.
