I took Tal out for a potty break this am and Midnight, my cat, came around the corner of the house. Well I thought I am here close and I will see what they do. They have never shown any antagonism toward each other. Well, they were looking right at each other about 2 inches apart nose to nose. What made it so funny is neither would make a move...it was like each was wondering who the other was and trying to decide what they should do next...Man I so wish I had taken my camera...they were so funny just standing there doing nothing..lol
