Frankie and I went for a walk Saturday. We made it to the other side of our next-door neighbor’s house when Frankie spotted a stray.

I have seen this stray many times in the past but not recently. I wasn’t even sure if he or she was still around until my catnip plant was destroyed.
Frankie ran toward the cat but ran out of leash and stopped. That scared the stray who ran to the left toward our house. Soon Frankie lost interest and became interested in a nearby bush. That is when the stray walked by unnoticed.

A little while later we came upon another stray cat that had no fear of Frankie or me being so close.

They howled at each other for a while. I was a little worried a fight might start so I took a step forward and caused the stray to run away. He or she ran under a nearby vehicle and the whole thing started over.
I assume the cat is a female or there would have been fighting sooner, but I don’t know. What do you think?
Update: I was wrong. Frankie did meet strays before. Here are two examples.
